Movies THX Ltd. started as a company with a directive to ensure that upstream quality in cinema audio made it all the way to the audience in the theater. In the movie theater, you need great power in order to get the dynamic range needed for impactful music and action...with a very low noise floor and low amounts of distortion in order to hear crisp dialog and all the detail in the recording.
Measurements Patrick Flanagan at THX is one of those quiet guys who goes about his business with an engineer’s mind and a craftsman’s attention to detail. You may have met him at a Head-Fi meet in California as Jude Mansilla has been able to have him offer some free headphone or IEM measurements to the community on multiple occasions.
We met him at the 2016 SF Head-Fi Meet where he provided us with some measurements of IEMs we were working on:

THX provides development and certification services to ensure that a whole range of audio products meet objective performance and quality metrics from frequency response to low distortion, with the goal of accurate sound reproduction.
New Technology The Massdrop x THX Achromatic Audio Amplifier (THX AAA™) 789 represents the next chapter in THX contribution to the audio world, where THX provides underlying circuit technology in the gear itself. The new design was born of necessity. THX needed amplifiers to power line arrays of speakers in their facility. Class A topology amplifiers run too hot and are inefficient to run for long periods of time. THX needed the cleanest signal possible, low noise, low distortion, cool temperature, and efficient power consumption. These requirements led THX and SVP of Audio R&D Laurie Fincham to revisit negative feedback designs, figure out how to implement feed-forward correction, and create the quietest, lowest distortion amplifiers.
THX Ltd. At-A-Glance: I. Highest quality sound for the utmost in cinematic experience (George Lucas’ original vision) II. Development and certifications for pro audio and audiophile gear (people like Patrick) III. Technological intellectual property in pro and consumer gear (Laurie Fincham’s amplifier design as an example)
A Series of Fortunate Events If we didn’t talk about Patrick, you might not know that THX is working every day behind the scenes to provide information to companies making audio gear…with and without the THX logo. And if we didn’t meet Patrick, this collaboration might not have happened.
Meeting Patrick at the event pictured above led to our visiting THX and seeing some of the measurement labs plus their demo room. (Fun stuff and just happens to be walking distance from our office in San Francisco!)
Visiting their headquarters led to an invitation for a sneak peek of the THX AAA feed-forward topology during the Rocky Mountain Audio Festival in Colorado 2016. We immediately saw the potential of this amplifier technology when we learned about it’s goals. Hearing the prototype- clean, clear, and natural (not sterile)...we knew that our community would like it too.
THX understands Massdrop’s connection with the headphone audiophile community and our drive to create custom-tailored products. THX collaborated with us to develop and bring this linear amplifier technology to you in this particular package, with the flexibility for in-ear monitors to large headphones. Capable for use in professional audio applications or for the audiophile that demands the most transparent upstream gear possible. This amplifier delivers the upstream quality of your music to your own personal headphone theater- in the comfort of your home or on your desk at work.
Massdrop x THX AAA 789 Linear Amplifier At-A-Glance: I. Lowest THD in class – world class transparency II. Extremely low channel crosstalk III. From low to high power – for your IEMs and your hard-to-drive headphones IV. Flexibility – from single-ended input/output to fully balanced throughput V. Form factor and usability - small, cool, efficient energy consumption VI. High value – high power and best performance at a low price point
By the way, we’re lucky to have Andrew Mason as a member here on Massdrop. Andrew is the THX expert in analog & power engineering who helped implement the THX AAA technology into our final product. If you have some technical questions about the amplifier, Andrew may just be around to answer them!

What tool did the team use to measure @143dB down?
BobthedespotHi Bobthedespot, We use the Audio Precision flagship APx555. It's the only audio analyzer on the market capable of measuring distortion this low as it maxes out around -148 to -152 dB. We've developed some special methods over the years and regularly collaborate with AP to squeeze the most out of the instrument. AP is using one of THX's AAA prototypes to demonstrate their 555 performance at various audio shows. Cheers, Andrew

AndrewMasonThank you for the response.
I'm surprised to hear that the APx555 can measure that far down... that's a thousand fold improvement in power sensitivity over the advertised spec, if I'm not mistaken.
BobthedespotIn my experience AP specs a "guaranteed minimum performance spec" that's super-conservative. Their instruments regularly blow it out of the water, especially the 555.

AndrewMasonHello and good day Andrew, could you elaborate and be a little more specific in how the measurements were taken? What FFT measurement bandwidth, bin width, window used, etc? Please be specific and technical; I'm an analog design engineer at a fabless semiconductor design facility that specializes in audio products. I'm quite interested in how these measurements were taken. Thanks, Steve

I would also like to know if I were to use XLR inputs, could I use single ended output and/or RCA output? I know you answered the inverse question yesterday about single ended input with XLR headphone output.
Jimster480Hi @Jimster480 . Yes! Using RCA or XLR-3 inputs will excite all 3 outputs to full power (3.5mm SE, 1/4" SE, XLR-4 balanced). Just search my name and company on linkedin.

AndrewMasonThat is great news, but i was specifically asking about the XLR input with RCA output. So that I can stack this in-line with another amp or speakers. My DX7 can only do RCA OR XLR output, otherwise it causes weird distortion noise and feedback (it warns against this in the manual). So Ideally I'd want to use my DX7->XLR output -> This Amp -> RCA Output -> O2/A30 Amp or my desktop speakers that I haven't gotten around to setting up xD
Jimster480@Jimster480 unfortunately we need a relay network that selects the signal to be amplified based on the front panel "input" switch: either from RCAs, or XLR-3's. There's no connection between XLR-3 inputs and RCA inputs.

lugnutWall-wart power supply doesn't matter. But its actually a floor wart power supply lol. Either way its fine as other power supplies don't really have any sonic differences. you can check the review of the D50 vs the DX7 or DX7s on audioscience review, the D50 got the best score despite having an external wall wart.
Jimster480@lugnut Yep the external in-line power supply causes no sonic degradation vs an internal one, improves reliability, reduces retail cost, and speeds time-to-market. Plus there's additional merit to keeping the stray fields from the AC/DC away from the audio electronics. The other product you refer to also has external AC/DC.

FrostyPNot all distortions are created equal.
Odd-order vs even-order.
Higher-order vs lower-order.

"The results of this study indicated that within the constraints of this simple study that the perception of linear distortion is dependent on the level and the delay time of the linear distortion and the playback level. The first two main effects were known as indicated in the background discussion.. However, while it may seem intuitively obvious, the significant increase in the audibility of linear distortion has not been shown before. Further, that this audibility of linear distortion increase with both playback level and with delay time is extremely important. These results mean that a subjective impression obtained where playback level was not controlled is of questionable validity.
The combined effects of playback level and delay have strong implications to the perceived perception of nonlinear distortion. It is not possible to say, without complicated objective tests, if what is being perceived is a nonlinearity in the system or a nonlinearity in the subjective perception as described in this paper. This has profound implications to the subjective evaluation of nonlinear distortion in audio systems most particularly loudspeakers where the delay factor can be quite strong. Time delayed resonances, nearby cabinet reflections and edge diffraction, waves in horns; all have delay times on the same order as this study. A loudspeaker that is evaluated at 70–80 dB (SPL) may have a very different perception at 90-100 dB even if it is completely linear.
A THD distortion curve will not reveal this effect, nor will a frequency response graph. A careful look at the impulse response might yield the best insight, however this has not been quantified. Methods for measuring the nonlinear effects of our subjective perception are currently under investigation. Another point is that the usefulness of a loudspeaker for audio playback can have a sound power output limit that is independent of its electrical power handling or its nonlinear distortion characteristics. Loudspeaker evaluations that take place at a fixed level, are seriously inadequate at revealing the true quality of these systems."

" ...before making the comment. I agree, discussion should always be allowed. But responding to hyperbolic commentary with hyperbolic commentary isn't really going to advance our conversation on the product or its design. There are, I'm sure, flawed wall-warts in the market place. But the question is, by analogy, whether or not you judge the Ford Mustang by the Ford Pinto, just because they're both Fords.
My issue with some wall-wort designs is based on the fact that it's a pain in the neck to use on a power strip. Floor-wart isn't as bad for me; at least there's room on the strip for more connectors. But then the length of the cable has to be sufficient for me to find somewhere to put the floor wart without just leaving it hanging off a wall or desk or something.

BlueSkiesSimple passthrough of DAC signal- so whatever your DAC outputs (2V?) that is just "passed" through.
Many people in headphone audiophile community like to have both a solid state and a tube amp of some kind to switch back and forth.

Mar 5, 2018
CEE_TEEOK thanks CT. And to clarify.. is the SE PASS pass-through at a fixed and constant level, or is the SE PASS level controllable?
CEE_TEE
3480
Mar 5, 2018
BlueSkiesIt is not fixed and also not controllable by the amp. Volume control will not have any impact and there is no gain or attenuation placed on the signal. Signal goes in the RCA inputs goes out the SE PASS as if there was a revolving door. Whatever comes out of your DAC or other source will simply come out of the SE PASS RCA jacks. This is just to give you ability to chain a source "to and through" the THX amp...

CEE_TEEThanks. Will the unit then turn back on with an input signal?
posposHi @pospos . To turn back on requires pushing the Power button. We decided to not have "auto-on" feature since to do so without impacting fidelity, it would have required more relays and circuitry, driving the cost too high. Of course if you prefer, set the switch to "bypass" mode and the amp will remain on forever.

Mar 7, 2018
CEE_TEEok, lot of questions. haha.

The power, distortion, etc specs say they are tested with 0db of gain, but the balanced output is not capable of even selecting that gain, its lowest is +6db gain. So are the specs listed under the balanced output measured at +6 or +0db? Also, are the gains different for SE and Balanced simply because of how the balanced signal works? Or are they running through seperate circuits with different gains?
What is the voltage swing of the amp? I like seeing the power specs, but it is nice to know what the voltage is so I can judge how much current it also has behind that signal to be pulled when needed
Lastly, since testing was done with 300ohm load, does that mean this amp is "best suited" for that load? I see you mentioned 12 ohm load as a minimum is fine, is that the amps actual recommended safe minimum?
EniGmA1987Hi @EniGmA1987. Specs are listed for unbal output and bal output both at min gain setting. I.e. 0 dB and +6dB respectively. Bal out gain is always 6dB higher to avoid necessity for a bunch of additional relays inside to swap gains around i.e. we wanted 3 configurations, not 6, with minimal gain/attenuation stages in the signal path. You can compute the voltage swing vs load by using P=V^2/R. Peak current limit is around 0.8-0.9 Apk. This amp is best suited for all headphones because: 1) Insane SNR, high Iout, and low Zout means excellent for IEMs. 2) Large Vswing means excellent for high impedance headphones. 3) High Iout, large Vswing, and low Zout means excellent for planar magnetics.
SpeakFriendHi SpeakFriend. Not yet. I'll add that to the backlog.

AndrewMasonHi Andrew,
The specs are really fantastic, but I am suspicious about whether these are measurements of the underlying topology, or measurements of this specific Massdrop implementation . The single voltage DC-in implies the use of a rail splitter, and those kinds of measurements are pretty unheard-of with such a power supply implementation.
I'd love to hear your comments about that, and apologies if my assumptions are off.
Best, Daniel.

TheSl0thHi TheSI0th, We have two units out for independent measurement and verification. Not just modules but the graphs from THX are measured from our amp samples. Jude at Head-Fi.org has a sample and we hope for measurements from his APx555 soon. The other is with Marv at SuperBestAudioFriends.com. I believe AtomicBob may be able to measure soon.
TheSl0thHi Daniel, The specs are for the entire Massdrop 789 product. The AAA core amplifier on its own performs even better, but it's nice to have all the little features like selectable gain, volume control, ESD protection, DC protection, etc. etc. And yes, we're using a THX-designed linear rail splitter to permit unipolar SMPS. Due to its feed forward error correction, AAA has nice side benefit of incredibly high PSRR to reject the small amount of ripple that escapes the splitter. Cheers, Andrew
BlueSkiesSE PASS RCAs are literally pass-through wires from one RCA pair to the other pair.
baiyy1986

Mar 9, 2018
AndrewMasonif the power is off, the se pass will not work, is that correct? so if I line up other amps with 789, I have to keep it on and then pass throw the signal? Thanks
baiyy1986@baiyy1986 the 789 pass works regardless of power on or off. RCA input and RCA pass are always connected to each other. But critically, the input relay isolates the RCAs from the AMP and ESD clamp networks when power is off. So there's nothing in-circuit to clamp your RCA signals.

CEE_TEELooks really good. One thing that would make it even better for my purposes is a 2.5mm TRRS balanced headphone jack. While I could convert the XLR to a 2.5mm TRRS balanced with an adapter, it would be more elegant and handy to have a 2.5mm TRRS jack right on the amplifier. (The reason why I prefer the 2.5mm TRRS connector is because that is what my Onkyo DP-S1 Rubato portable DAP uses for it's balanced headphone jack, and it is a common jack on portable players from other companies as well such as Astell&Kern, Pioneer, etc. and at this point I've invested only in balanced headphone cables that terminate in 2.5mm TRRS.)

Kr8nuxNot at the moment- we're getting the Balanced SDAC up and running first. With all of the inputs and outputs on the Balanced SDAC in such a compact size, we think the community will be impressed and able to enjoy the SDAC-B in many combinations. Especially with the Massdrop x THX AAA 789!
EniGmA1987
607
Dec 27, 2018
CEE_TEEI know Massdrop loves the SDAC they helped create (probably cause its your only DAC right now?), but it really doesnt have the truly impressive SINAD specs to go with this THX amp. The SDAC really only measures just a bit better than a basic JDS Labs ODAC. Couldnt you get a project going with the specific goal of making a balanced DAC that sounds just as exceptional as this amp and has the THD%+N specs to match with this? Currently the closest thing (and it does come very close) to match with this THX amp in a similar price range would be this DAC: https://www.massdrop.com/buy/smsl-su-8-dac Edit for Jan 2020: As of now, the best DAC to pair with this would probably be the Topping D90. It measures as one of the best DAC on the market and has balanced outputs. The D90 measured specs match this THX AAA 789 very well.

Dec 28, 2018
EniGmA1987That was my reaction as well, the THX 789 deserves a better than a good budget DAC. I'm using a Mimby with it ATM and would be interested in an upgrade later this year (it has to be later this year since buying the Elex and THX in the last month). Possibly the best match from MD would be the the Airist R-2R both in quality, price, and the added advantage of perfect stacking. My guess would be that this DAC is likely to drop again in the next few months, unless there is some problem with the IP issue, which probably also held sales down when it dropped earlier this year. I know the R-2R is not balanced (at least not yet) but it appears that a balanced DAC does not add that much to the THX given its topology. Another interesting possible upgrade would be the Topping D70, a fully balanced DAC with a ton of features that is expected to be released sometime in the next few months at $600.

AndrewSimI saw this at 11pm(Singapore time), when the drop was available. Unfortunately I was in bed and thought I’ll book it the next morning when I wake up. If I knew it was limited, would have sprung into action. Its kind of unfair. I hope I’d be able to get one the next time.

LuckyEightsIf this drop was for preorder and these 500 units take 2-3 months to be manufactured, it means we ll have to wait till May for the next preorder-drop and we are lucky if we get our unit by the end of the year.. I didnt know that the manufacturing process takes so much time... Hopefully something else appears meanwhile coz i m fed up waiting for this. I 'd go for the Jds Atom also but it s not balanced

AndrewMasonAndrew, what do you mean? Even if you are only using RCA inputs, if you hook up balanced headphones you will get the power benefits but not the "extra" balanced clarity?
pantagYes regardless of RCA or XLR input, all amp output are driven to full power (including the balanced output). The "extra balanced clarity" people talk about might be due to reduced crosstalk, reduced hum, or high voltage swing inherent to bal-in/bal-out systems. With RCA in / bal out to the 789, you still retain the crosstalk reduction and high voltage swing.

AndrewMasonThanks! Two questions. Where can I find the online manual for the AAA 789? Why a preamp was not included? It would be especially useful, as most of us run powered monitor speakers where we could control with the volume knob. of the AAA 789. Now, we have to connect the speakers to the DAC, hoping its volume implementation is not cumbersome or use an external passive knob to control volume, since RCA outs are full power line level. It just seems like a big miss on this end...

pantagHey pantag, There are a few reasons for not including a pre-amp out function on this amp. Would require additional switching on front panel or an auto-switching feature. Would require more outputs on the back panel and close to the power input circuitry which can get tricky with noise. We wanted to make the amp as flexible as possible for all headphone/IEM/driver tech/impedance listening use cases while also friendly to newer users: passthrough of the DAC will be at fixed line level and not blow out someone's new active monitors, easier to use/connect, lower cost of entry...but we hear you on pre-amp usefulness. Will bake it in where possible. Thanks for the input! Er, output. :)

CEE_TEEThanks for Awesome product. Was hunting last 5 months. Finally got it (even ordered two). So, the next small request is to make a good balanced DAC in the same form factor, so a lot of people who bought AAA 786, Cavali and Liquid Carbon will buy it to match the stack setup. This market gap is still open and will be on high demand if you will make it as good as AAA-789. Regards, Kim

CEE_TEEI'd like some obvious indicators on the knobs. I don't have great lighting in my room, and I basically have to return the knob to 0 before listening to figure out what the volume should be when I switch headphones. Maybe a second 1/4" jack to run a second pair of headphones, like Lake People often include. I want to side-by-side t50 mods but can't
JJayJJ

Apr 5, 2019
CEE_TEEWonderful as it is now, maybe an indicators on the knobs so low-light isn't a guesswork? The only other thing would be, seeing as how efficient the unit is from a heat perspective. Perhaps a design with an internal power supply? Or perhaps not incase it goes bust down the line, I suppose replacing a power cord with a brick is a far better solution as you currently have going. Just please.. for the sake of everyone's sanity, could you comment on availability or anything pertaining to future timelines?

JJayJJ

Apr 5, 2019
jm090That would be a totally different device. Also it would be nicer if this version can stay as is, andnthey build a DAC separately. The time it would take to redesign this to have a DAC portion would take who knows how long. Also since you say internal powesupplies can cause interference, but a whole DAC unit has far more potential to delay designs if the amp portion suffers as a result of having a Frankenstein implementation for an amp that wouldn’t meant to be modular in that sense (power supplies can cause distortion, but when properly handled, this isn’t an issue, and as I said in my first post, I don’t think it’s a good idea when I thought about it, it would just add unneeded cost and complexity and size to the unit). But the biggest problem, is cost. This unit would not cost the same. So would be better if they just made a separate DAC entirely and let users mix/match.

jm090

Apr 5, 2019
JJayJJdo you consider the CTH + SDAC or LCX + SDAC a completely different device from the the CTH or LCX? I would prefer a standalone dac option that is in a matching shell but that was not @CEE_TEE 's question. on to his actual question though, i think another good idea would be to build an SE version of this amp that is slightly more premium then the Atom or Magni, yet more affordable then the full THX 789 for more mid-fi level users that havent started with balanced cables.
jm090Massdrop did make a DAC in a matching case, it was the Airist R2R, also the SMSL options matched but not quite in the same way the Airist does. The THX AAA 789 is mid-fi. Look at it like this, if you have no balanced cables etc yet, it can be used “low-fi” SE like the magni/atoms you mention with a much higher buy in price but also offers future upgrade ability to go balanced.

jm090The first part of the post I don't know because I don't know anything about those devices. As for your next suggestion, the buy-in price is perfectly fine and it offers SE anyway. Reasons being: 1) It measures the best out of almost any amp, and certainly the best at the price, this is regardless of features, or inputs. 2) Since it does measure the best and is in a nice package, making a "SE" version is going to do nothing aside from warrant a whole new schematic where the cost savings wouldn't be as much as you'd imagine. The future upgradability for anyone who ever considered this device is a massive selling point. Again I iterate, buying a AMPDAC is just going to raise the price, and do away with mixing/matching at the price level, then the second portion about making an "SE" version doesn't make sense as it now argues the opposite of your first suggestion (a pricer and more complex version, along with now the SE version which would be slightly cheaper, but now with no DAC as you wanted before, and pointlessly trying to shave off a few dollars for what is essentially the most desired amp in the industry right now at the price bracket, aka demand for a product people will actually pay for, unlike multi-thousand dollar amps that are great, but no serious demand of this number exists for). By that, I just have to say, what you proposed as suggestions are pretty undesirable and don't make much sense to invest in. I'd argue especially the last point, the fact that the 789 measures so well, and has S-E AND Balanced is what allows it to retain it's desirability and value from entry "hi-fi'ers" and people willing to pony up more for balanced. When you split this product into a version will SE, I have a strong feeling it wouldn't have the same pedigree this does with respect to value retention. Unless of course you're here arguing that chopping the Balanced feature will somehow result in a 50% price decrease or something of that nature.

CEE_TEEWell, knowing I would never get a chance to have and own my dream 789 AAA amplifier, I was hoping would there be another ones at least make up for it. If possible, a better version meaning improvement of lower distortion and improve audio quality which am not sure if its possible because the current 789 is perfect from what I heard. Also, I would like you to have add a bass boost and other features. Having more features is nice giving us more decision to choose from to add the extra immersion. If we dont like it, we can always not use bass boost either way. Maybe increase built quality and the satisfying click knob ? Which is already good. Would appreciate it if the next batch would have bass boost. Games and movies would sound good.

CEE_TEEI already have two of these amps from the first drop, but here is what would make me instantly sell them and buy another pair:
  • Replace the stateless push button with a real on/off button, so that the amp can be made to automatically turn on when main power is turned on when the button if left in "on" position
  • Alternatively to the above, add an "auto on" feature to complete the "auto off" one
  • raise the max current limit a bit, maybe adding internal heatsinks where needed
Other than that I find that amp perfect! Kudos to @AndrewMason and massdrop, once again :)

  1. Better volume knob indicator
  2. Instead of power button, put in one of the airplane style toggle switches (OMFG Please) or you can use that for the gain settings, and the gain knob for power because that knob is amazing.

Or at least make it with cable replace e t, you know.. 8) THX, take in considerations all the points, you are nailing it.

ImNotAnAudiophileYeah separate power supply is great, i want SMSL D1.. Why you disagree on powah?
Viper_NecklampyI mean there is no reason not to have it first of all, if you can get this much power and be clean as the 789 why not, and some headphones need the power, like my Modhouse Argon's. My Cayin IHA-6 delivers 7 WATTS at 32 ohm and is fully balanced lol. Also, I got the SMSL D1 here on Massdrop for $900, good deal. I believe the D2 is coming out soon this year too.

ImNotAnAudiophileOh do you think SMSL D2 could come this year? Damn, what more they could improve, apart some units that broke after few days.. If that's so maybe i should stay away and wait, with Topping D50 and Jds atom is not that bad. Actually i don't get the point why people tells an amp is 'underpowering that headphone', could you explain how the sound feel 'underpowered'? I have an atom, in low gain in normal content easily with Audeze El8 Titanium and even more when i'll have Lcd-x
jm090

Apr 17, 2019
Viper_NecklampyThe atom delivers almost 1w to 50ohm, there are very few scenarios you would be "limited" on power. There is differing philosophies on the benefits of amplification vs being loud enough, but I firmly believe that even headphones like the hd598 benefit from a bit of amplification to open up the range a bit, it's also why I hate when people compare hd598s to the hd600 range off of motherboard sound. Off a Mobo the 598 is 90% to full potential, but there hd600/650 are at maybe 60%.

Viper_NecklampyDon't listen to some of these folks. An Atom + D50 is more than enough power to drive virtually every headphone. Not only that, but you're essentially at the cutting edge of performance with respect distortion/noise metrics. And certainly at the price points those two are offered at. If you have the D50 and Atom, you have nothing to worry or want in terms of performance for quite a while. Unless of course you're looking for features (like wireless streaming point, or things of that nature), there is no reason to move up from an Atom to anything else amp-wise if all you're using is headphones.
Viper_Necklampy

Apr 24, 2019
JJayJJBut i think no one would argue that Smsl d1+ thx aaa 789 vs Atom+D50 would be better in sound quality overall, i mean, even Zeos Pantera says he can hear the difference with THEESE gear 😂 , and he is cable and filters skeptical etc.. So, i would think that d50 and Atom is more than enough, sure, but something like SMSL d1 or D2 + Thx 789 is marginally/considerabily better, i mean, in terms of soundstage, cleanliness, Power, DYNAMIC RANGE, crosstalk, and god, that dac... Anyway, if you use headphones on low gain, the ''underpowered'' thing is still real if you near-to-max the low gain?

Marginally better: Probabaly Soundstage: This isn't actually a measurable thing, soundstage mostly has to do with channel panning, reverb, and source of the recorded material. I have never heard an excellent headphone (with respect to distortion and such) that had "bad soundstage". So no, I don't think this could give more or less soundstage, and I'd wager literally any money, that not a single person on this planet can blind test "soundstage" between DAC's/AMP's if they had decent power to drive the headphones being used. Cleanliness: Probably, but this is literally splitting hairs, the Atom and 789 are neck and neck with this respect in terms of SINAD, but that doesn't tell the whole story, so I will agree the cleanliness is probably better with the 789. As for the D1 vs D50, I agree it should be a tad better if no anomalies exist like they mostly do with inter-modulation issues of ESS DAC chips used in many higher end DACs lately. Power: I agree with you here, there is more power. But you will never use it, if you manage to use it with respect to headphones, you'll be deaf soon enough. Dynamic Range: I agree with you here, but this needs to be confirmed with measurements (it's easily measurable). For the DAC's there might be a difference, but for the two AMPs we're talking about, the dynamic range is basically identical. Crosstalk: No idea >_< God that DAC: It does look nice I do admit ;P

Apr 24, 2019
Viper_NecklampyYes, if you're maxing out the volume knob, I guess you could say it's low powered (or you might be suffering hearing loss). But that's why Medium, or High gain exist. In good AMPs, this will not create some sort of awful distortions just because you use a higher gain. Though some AMPs do have worse performance in some metrics when you go full High gain.
Viper_Necklampy

Apr 25, 2019
JJayJJThanks for your time, really :) Well sometimes i find with EL8 titaniums and Atom to have the volume near max on 'low' 1x gain, while on thx 789 balanced on low 0,33gain would have even more power than low gain on atom, i think.. if not, medium gain 1x would be even more 'ok' Well crosstalk is the separation of the drivers, in atom is -90dB, it's very good and kinda enough if you don't want perfect separation, but Thx789 is - 127dB, more than enough, some would argue that on speakers crosstalk is more natural but, i'm an headphone guy and i like the way they are.. Dynamic range, Atom have outstanding around117dB dynamic range, but Topping d50 Dynamic range isn't measures by Amirm, even if i asked him, so i might think is not that good, so the Atom range would be cut to around 103/110dB, still nice, i heard somewhere that 120dB+ is required, i don't remember the why unfortunately.. Thx789 is 127dB, and D1 too, so Dynamic range would be outstanding for sure, anyway, i even heard by Dyiaudioheaven site owner that dynamic range is not that required, i still think dynamic range play a very important role.. So crosstalk, dynamic range, power, trasparency, are way more than enough than you would ever need, on that.. But d1+789 are 1600€, vs 350€ of atom and d50, 5x the price, for marginally better performance and 10x size lol For what? I still don't know why, until i hear, but i think they will better, marginally or more, depending on your earing xD As for soundstage, i know what i will say will not be liked by most but, you can pass this or don't judge me :) : until contrary prove, my two cheap cables of 10+10€ (Optical and RCA) on atom and D50.. Bought 160€ used cables total and i find soundstage better, and with that, fraction of imaging.. So soundstage is better on my EL8 Titanium, and i find sound overall better with that, not by a slight margin, i would say 2-5% better, not the first time that i could pick difference on cables.. that's why i will spend a very good amount on full silver cables for my d1/D2 and thx789, and maybe Audeze lcdX :) Cable skepticals, delete in your mind on what you just Read ahahah i know what ya thinking xD So yeah +++ €$ spent for a little more performance, just buy 'cheap' 300$ stuff and be totally happy.. Anyway if you'd like i will tell you when i'll have all the gears what i will think about of Thx789, D1/D2 and LcdX, hopefully in next 6 months Max The only thing that could fear me, is that i hear thx789 after 1000hours start to degrate sound, and after 5000hours could be even worse if not stop.. Hope that is not real, i will ask more..

Having bass boost is just an option, dont use it then", which I read as you basically acting as if I don't understand people want things and a snarky considering I was discussing adding digital filters to an analog circuit. sorry, timing of the responses made it look different. On the monoprice 788... You may have to be patient with that one as I understand the firmware on it is still a little "buggy".

lugnutI know this is an old thread; my musical fidelity X1 and nakamichi soundspace want to have a word with you.... (both are audio kit with massive improvements given due to ‘outboard’ power supplies) I’d definately consider items individually and not write off every future part (even by other manufacturers) due to one bad experience. having been a couple of years, hope ye have healed over this. To other readers; I’ve been gaming since the 70’s. It’s generally the ‘cheaper’ gaming consoles that included the power supply inside. When the playstation launched, it required being turned off at the wall due to ‘internal heat’. The first xbox, power unit was internal, the x360 and it went outboard.... high quality outboard is ‘alright by me’....
