Okay folks, I've had the A30/D30 combo for a couple of months now. I put in the Burson V5i Opamp upgrade. I highly recommend if you're looking for an improvement but not wanting to buy a new amp. I have a question I'm hoping someone can answer. The A30 has a 3 position power switch; off, low, and "hi". I know from the owner's manual that it selects between low and high operating voltage. My question is when would it actually make sense to use one over the other. I've used this amp with HD58x Jubilees, HD6xx's, 32 ohm M&O's (32 ohm), some low impedance Betron IEM's. For the life of me, I can't tell a difference in sound quality or quantity between the 2 settings. The volume level doesn't change as it does when switching between gain stages. I'd like to understand why this option is even offered if it doesn't functionally seem to do anything. Thanks!

These are good for an Beyerdynamic DT770 250ohm?
Man, Massdrop is kind of a joke now, which is pretty sad because they have great stuff all the time. You can buy these on eBay direct from the manufacturer from China for less than they are offering with free shipping and they will even arrive BEFORE these ones when coming from China, these say they ship Jan 15th, the ones from China ship right away and arrive within 5-20 days. I was right on the fence for buying these and saw they were here and was really happy, until I got to check out. Hell, even from Amazon with free 2 day shipping it's only like$20 more. I have seen a lot of "deals" like this recently here and it's pretty darn sad. The RAM deal they have now is the same way, $140 for 16GB RAM, when you can get BETTER RAM on Newegg for less atm.

Yeah, thought the same. If you are from Europe, amazon.co.uk sells it for even cheaper than this.
Is this a good choice for the Massdrop HD650s?
kermiter
Yeah. Both would work well, DAC and Amp. Now, some will say a tube amp would be best, but for the price and ease of this combo, you get one of the best single-ended DACs at the price range and a decent solid state amp.
Unfortunately I can't afford the D30/A30 set this time. Hopefully this drop happens again.

You're in luck
Would somebody be able to tell me if the sound of 320k quality mp3 files would be affected negatively by the D30 Dac? It says support up to 192k but not past that...

Thank you kindly for the knowledge

The 320kbps in the mp3 is the bitrate that the mp3 was encoded at. That's kilobits per second. The 192kHz is the sampling rate that the D30 is able to decode. That's kiloHertz. These are two different quantities. I imagine if you look at the coding details of your mp3 files, you will find that it is encoded at far lower than 192kHz, probably only 44.1kHz.
I'm a little confused with which models I will need if I want to play bookshelf speakers from my PC and also listen to my PC with headphones. Do I need all three? I know at the very least that my speakers will need to be connected to the PA3 Amp. I wish Massdrop would have shown the back of the devices as well.
Thanks for the help!

You need to connect the PA3 to a source, a DAC helps with connecting to a PC source, but other sources may not need the D30. Essentially, if you can connect from a DVD player to the PA3 with cables, you don't need the D30. Most PCs don't have that direct connection with RCA cables, so most times there will be a DAC to convert from USB from the PC to the DAC, then the DAC converts the digital from the USB into analog for the RCA cables for the amp to take and increase the power/sound volume.
Nasp
The D30 moves digital audio to analogue audio. Your PC can give the D30 clean digital audio through USB connection. The A30 amplifies anologue audio for a set of headphones. The PA3 amplifies analogue audio for a set of speakers. They are each boxes specialised to be great at one task. If you choose to go with such a setup, you'd call it a "modular" setup since you can upgrade the box for a particular task one at a time, rather than having one box that does everything.

I would not recommend the A30 for those headphones, it has a very high output impedance of 10 which will make it a poor match for your low impedance headphones.
In the 200 or less arena, the Schiit Magni 3 is a good choice if you want a preamp too. The Liquid Spark might be solid as well but no real reviews out about that yet. It certainly looks exciting. Its specs are slightly worse than the Magni 3 though.
Vishmaw
I appreciate the heads up on the impedance matching!
I've heard the Magni 3, and it had a "metalic" or sharp sound signature that I didn't care for. Ideally I'd love to get a Schiit Asgard, or BasX A-100, but it's not in the budget. The Spark just caught my eye as the Cavalli amps always seem to be well regarded.
I love my D30/A30.
To confirm, the A30 will not come with an AU/NZ plug if I choose the 220v option (and I live in NZ)? I presume the switching power supply for the D30 will be easy enough to change, I imagine the power supply has an IEC or similar cable plug that can be swapped out?
Ok this is a realily stupid question but I can’t seem to get a straight answer. So I have a pair of R-15M speakers hooked to a Sony STRDH 190. I don’t really listen with headphones often. Really all I have done with my fairly new setup is stream Spotify from my iPad Pro. However, I have a lot of audio files on a PC that I can’t seem to get to play. Would this DAC help me? In other words, I want a means to connect my PC to my receiver but want to bypass the DAC in the PC. I appreciate any and all insights into this Cadillac problem I am having. Al in Oakland

Wow! You are totally awesome for going above and beyond to help me understand this simple, yet somehow baffling, situation. I'm by no means an audiophile but am beginning to get back into it. I had a brief little swing with B&O in my mid 20's and for unknown reasons or no reason at all the trajectory of my life changed rather dramatically, which included the loss of and consequential disinteret with the brand and its whole aesthetic. So yeah, I have been building up a little system but instead of just throwing money at equipment I neither need nor understand, I have been trying my best to do this slowly and deliberately. Everything you've shared with me here has been really informative and interesting; so much so that I will probably pull the trigger on this one. One of the disadvantages of my receiver is the RCA jacks are in the back, which makes hooking an iPhone or DMP up to it not that easy, especially if you have a bad neck.

" One of the disadvantages of my receiver is the RCA jacks are in the back " mine is like that too, i just use a 3ft RCA to headphone jack and run it under my amp out the front. I just leave it plugged in all the time so i dont have to mess around in back. the jack sticks out enough i can grab it, but i can also slide it under the amp out to be of the way.
you're welcome for the help, i got turned off from the audiophile / vinyl communities in my 20's because it was full of d-bags and elitists. i guess it's always been that way. The mentality that you need to spend thousands of dollars to have a worthwhile setup is just so off putting. keep on trucking, and dont let the pricks keep from listening to good music.
I'm new to Massdrop, so I'm not sure how pricing works. When I select the D30 and the PA3 the price is close to double what it should be. Even when I select a second option, before I select anything, the price jumps. Is that the actual price, or will it be 104?
Is this drop for each individual unit or bundled together at $110?

No worries. In my experience, there's a 50/50 chance Amazon will have a lower(albeit slightly) price and zero wait time for a drop.
It's a complete crapshoot on the value, usually.
Well, the wait time is longer, but the current pricing is $40 less on Massdrop for the A40/D30 combo.
Is it any good for the sennhiser hd650 or hd6xx?
Teslafront
Absolutely. Assuming you're purchasing a dac and amp stack (for best results), this will be more than adequate for your needs.
Again, I highly recommend buying both a dac an amp for the cleanest sound possible. The dac will do the work of converting and polishing the signal so it sounds crisp, clear and noise-free and the amp will of course amplify the signal flowing to and powering the headphones.
I'm trying to run this off a raspberry pi using volumino. Usually I just plug in the dac and off it goes. It is playing pcm fine, but not DSD. Anyone have any answers for me? All my other DSD dac's which I've tried just work... something is getting in the way here and I'm not sure what. I was fairly sure it was capable of direct DSD playback unless I'm wrong?
Can I use the D30 DAC with the O2 Headphone Amplifier I purchased rather than the A30 Headphone Amp?

Does the length of cable influence EMI?
Noon6
The idea is that you can make a free, essentially "powerless" radio by hanging a long copper wire (inside most cables), grounding one end and the other goes to a DIY radio with simple parts and you can pick up a few radio stations. The wire length determines how strong the sound is, so the longer the cable, in theory the more possible EMI is and how loud it can be. Typically you need 20+ feet for efficient IEMs for any respectable volume for such a radio, so your typical 3-10 ft shouldn't be too bad.
Is there an option to get all three - the DAC, head amp, and stereo amp? How about just the head amp and stereo amp? I don't really need another DAC.
yogiwp
I clicked "join drop" and I was able to select quantity and model I want. Then below that I could "add another order" with the same prompts as the start allowing me to choose a new model and quantity. You can see for yourself. Just be careful not to keep hitting join drop once you've selected the model and quantity because I think after that screen the order gets placed.
Michael-Q
Thanks. Looks like now it works--it wasn't shown like this a couple of days ago.
When they include a AU power plug i will purchase. (or free adaptor)
Load 1 more comment
tl:dr no, it doesnt include one (or the option for one)
DamienR
Sounds like no, but all you need is an adapter to fit the plug since it has the correct voltage. I remember frying some of my stuff because I had an adapter but not a transformer to switch from US 120 to EU 240, luckily it was the power plug and not the unit/phone I was trying to use.
What power supply does the PA3 amp comes with. The standard or high power version?
search
Ok, any help on this decision? I'm running HD 6XX & the new HD 58X as well as pc37x (50 ohm) once in a while. I would also like to be able to add a pair of bookshelf speakers and a sub eventually, but that is lower priority at the moment.
This (D30 + A30) or the Aune X1s (10th anniversary edition) that is available right now?
OR... spring for the extra $100 bill (roughly) and get the D30 and the Aune X7s?
With the X7s, I know it is a serious piece of gear, but I'm a bit unsure about going class A and having to fiddle around for the on/off toggle all the time to keep it from heating up my office more than my personal PC and work laptop already do. Also, I don't have any balanced cables yet and not sure I'd see much benefit on the SE out of the X7s vs the X1s 10th anni. That is easily rectified though of course, down the road, with a bit more of the green stuff to buy a balanced cable.

Thanks for the reply. How has it worked out? Any complaints on the D30 + X7s combo? Any pics of the resulting "stack"?
JeremyP
I just joined the drops now. So I can't really tell, but by the reviews X7S is a beast of an amp and the D30 measures very well, and they say it is very natural. I don't know if the A30 is any good, but going separate dac and amp enables you to upgrade in the future, I know that hd650/600/6xx looove tube amp, my plan is to get tube amp in the future. I wasn't sure about the X1S I don't know if it's better then the topping stack.
Would this recognise and play music via Samsung S8?
I am looking for a dedicated phone only DAC/Pre to link to my larger amp.
Will this DAC play SACD's through it???? Please help!!!

I believe there is no such thing as dsd out from a SACD player. So no DAC will help you with that
Bob3600
I read somewhere else that it only works through USB or via Toslink......I tried hooking up my SACD player but only have a coaxial output so it doesn't work but CD's do work. A little PO'd.
Is there a way I can order A30 with both 110v and 230v power suppliers? Thanks much.
This is a great DAC/amp but this price is normal. Do not join this drop.
FuckHead-Fi
Indeed I've been looking online and its almost the exact price as what is found on Amazon. Why is this do you think?
What is supposed to make me think that these would actually ship out this time around?
Hi. I have a question about the line out on the amp A30. Is it fixed volume output or variable? Can I control the volume of my powered speakers directly from the amp?
already the same price everywhere, why are you waiting. NO ADVANTAGE

That might be because of it's power. Since bass is harder to drive, unless an amp is altered to unnaturally change the sound, a more powerful amp is going to make headphones bassier and warmer. If you don't like that, maybe look for a more bass light headphone, or use a little bit of EQ to bring it back down. Don't blame the amplifier though, it's just doing it's job.
EnsisTheSlayer
Yep, you are right~ The power of Magni 3 made my darker headphones like 650 and fidelio x1 sound better, tighter in bass. But my favorite 63 ohms light-bass CD900st sounded blurred in mids and lows. I don't think EQ will help, everything sounded smoothed, "richer" with less details, I don't know why, maybe the power of Magni, My previous DAC "only" has around 700mw into 32ohms.
Brand new Topping D30 DAC, I noticed it connects fine to my Macbook Pro via USB but is only recognized as a device on the Mac if the Macbook is on battery power. As soon as I plug the Mac in, red light on the DAC starts blinking and the DAC disappears from the device list on the Mac and connection is lost. Is this a common problem? Tried multiple USB ports on the Macbook, but same behavior on all.
