Hello Everyone,
Sorry it took a while, we did hear you.
There have been 6,647 requests for another drop of the Massdrop O2+ODAC DAC/Amp Combo: https://www.massdrop.com/buy/massdrop-o2-odac
We were not able to continue offering that version at the price point that made the product accessible, so we reached out to Grace Design for a new DAC that meets or exceeds all of the ODAC specifications (at a reasonable price).
Please meet the new Massdrop Objective 2 + Grace Design Standard DAC (SDAC) combo.
Designed to measure well, sound transparent, and be affordable.
Michael Grace does a great job of explaining some details about the SDAC here: https://www.massdrop.com/buy/massdrop-x-grace-design-standard-dac/talk/1806625
In addition: Since we have several DAC & Amp products available right now, here’s an overview to help with your options…
DAC & Amp Family UPDATE 9/18/2017: https://www.massdrop.com/talk/2363/audiophile-custom-products-dac-amp-update-9-18-2017
Thank you so much for all of the requests and support!

Thanks a lot for the update. Is it still projected to cost $150?
Thanks for the update. Looking forward to the drop.
Can someone sell me the Purple Heart box sticker with burgundy lettering and white lines?
So, No power supply included with this unit?? maybe I'm not reading it right
doegimedasht
They have the 220V power supply just not the 110V one.
Update on the 110V option.

I picked up a PS from JDLabs and will comment on it when they both arrive. In US ordered the 220V
https://www.jdslabs.com/products/147/15vac-power-adapter/
So annoying that there isn't a 110V option. Tempted just to buy with the 220V and separately get a replacement 110V...

Which model did you get? 12V? Triad WAU12-200
yfactor86
That's the one.
Any ETA on the 110v option? Just got a pair of 650's and am dying to push them!
I live in USA and the 110 is out. Does the 220 works the same in US?
Gingy
No, it does not. It is a type A plug which is what's used in the US, but the vast majority of people in the US don't have access to a 220v type A outlet. You'll only find them with a different plug type for your appliances (washer/dryer/etc.).
Does anyone have an idea how long it will take to ship to Switzerland and what the tax rate is? Thanks in advance.
Just got it. However, I got a 220v adapter with a Type A plug, instead of C or F.
What the hell? Who uses Type A in Europe and what's the point of offering a 220v with a Type A?
Can anyone tell me what kind of a adapter I should be looking for now? The power supply that came has output marked as 12 VAC, but I can only find power supplies locally with 12 VDC, so I am not sure if that the direct over alternating would make a difference.

Never shopped on ebay before, not sure how reliable sellers are in that space.
That's interesting, I don't understand why the power brick change would affect the driver installation...
Just a few minutes ago I got offered a refund for my unit, I guess that's what I'll do.
Can someone help me out ? Is this or the SMSL T1 DAC/Tube Amp better ? I plan to pair it with a HE4XX and (possibly) a Messe 99
Is 220v even viable in US? As far as i know You only have 110? Why in the World is the AC adaptor a US plug...
Waiting on the 110v AC adapter to be back in stock...
Just joined this drop. Kept reading stuff about people getting insufficient power adapters. Should I look at getting a replacement one right now? Or should I wait until I get my dac/amp?
SourKimchi
debating on getting the 220v and just buying a replacement 110V since its out of stock. Hope someone answers this.

I did that and bought a 110 Triad from Mouser for <$20 shipped.
Is there a discreet way to hide/cover the bright red light on the front of the unit?
EDIT: Just figured out I can have the power off and still pass audio through to another amp. That's pretty sweet.
Mark_M
yeh that red light is not subtle. first i thought something was wrong with my unit
But i found that it doesn't distract me like other units with blue or white LEDs
Does anyone know how to use asio output on SDAC?
Load 1 more comment
From what I know there is no ASIO driver for the SDAC.
OpasTanti
So i cant do dsd on this, well , they dont accept returns
Is anyone having the same condition as me? It stops outputting sound every random period around 10-15 minutes, and I have to replug the usb cable to reset it.
GTeee
I only had that issue on the first thing I plugged it into. Plugged it into something else, and haven't had any issues since.
GTeee
I'm having this issue as well... Let me know if you find a resolution.
I wanna participate in this but then they were out with the 110v option. So if I buy the 220v option, will I be fine if I just buy a separate power supply to make it work in the US? Or is there any update with the 110v option being available?

So the 220V power supply will work the same in US?
Gingy
The power supply, no, it won't work per se. But the O2 itself, yes, you only need to find a 110v power supply, or a voltage adapter.
I have the JBL LSR30X, which have an annoying buzzing sound, which apparently can be fixed by using a DAC. I also have a pair of headphones I'd like to use with the AMP. Would it be possible to connect both my headphones and powered speakers to this?

Thank you for answering my question. I have two more quick questions. From what I remember my speakers use RCA (on the speaker end) which terminates to a 1/4 jack, which I use to connect to my computer. If I were to purchase this AMP/DAC and use it in the configuration I initially mentioned then I would have to purchase an RCA to RCA cable, correct? Second question is that if I use the RCA line out to the speakers will the AMP behave as a pre AMP or will the speakers only be influenced by the DAC? Thank you.
Sunreeper
1) Correct if it is exactly as you mentioned, but aren't the inputs on the JBLs XLR and 1/4 TRS; if so you will need either a RCA to XLR(3pin) or a RCA to TRS(1/4)
2) The speakers will only be affected by the DAC
Selling this if anyone wants to avoid a wait. Located in Australia, so shipping to Australia only.

I was using it for the HD6xx and Pinacle Px. Yeah I only used it for my PC. Easy, I’m located in the ACT, so shipping shouldn’t take too long.

simpson.photographics@gmail.com shoot me an email for details man
Are the rear RCA outputs pre or line out?
harrisonjr98
line out straight from the SDAC.
harrisonjr98
They can work as line out from the SDAC, when the USB is connected to any source, or line in for the O2 when there's no USB connected.
Can I run RCA out from this into another amp such as the Aune X7S?

I think I figured this out yesterday after my stand alone SDAC had begun shipping. lol Oh well. Worse case I can sell the O2/SDAC online. I do like that when using just the DAC the red light is off. It's pretty bright. There is a red light on the stand alone SDAC as well but due to it only being USB powered I don't think I can turn that light off. I'd have to find a discreet way to cover it up.
Mark_M
I could buy your O2/SDAC combo, if you're willing to ship it to Spain and we find a deal. Let me know if you're interested ;)
How would this compare to a Schiit Fulla 2?
hazardeus
I think someone asked the same question in a thread a while back: https://www.massdrop.com/buy/massdrop-o2-sdac-dac-amp/talk/2210877
I think he end up buying both and find that O2/SDAC is a noticeable upgrade. So I'd say probably just get this lol.
Does the power plug support 240V/50Hz?
Would I be able to use the SDAC and use a different amp? I wondered before I bought it If i could upgrade to a different amp later on and just use the SDAC on it.
Aloog
Yes this unit has dual input/output RCA jack at the back. So if you have USB port plugged in then the RCA will acts as output from SDAC then you can hook up to your own amp. When the USB port is unplugged then the RCA will acts as input and take signal from other external DAC and then pipe through the O2 amp internally then you can listen through the headphone jack.
Just wondering has anyone tried using O2+SDAC to power IEMs. I have a variety of IEMs and only 2 pairs of open back, so far I been sticking with ibasso's portable AMP/DACs and I would like to try this. but would the lowest gain be too much for IEMs? targeting primarily to K3003, earsonic sm3, er4b, e5c and my ue11. Thank you guys.

thanks man, this helps a lot. and yeah, i do believe that DAC plays a more critical part when powering IEMs. However, i happen to notice that even for IEMs with low impedance and high sensitivity, an amp does make a difference. like for my k3003, there is a pretty noticeable difference when i hook it up with my old voyager from graham slee (a more holistic sound stage and a richer sound in general) than directly from my small ibasso AMP/DAC. I am using a DSD output from my pc to DAC so the output power pretty much all depends on whatever amp I have. so did you hear a background noise at 1x gain with your TF10 at low volume? Thats what i was worried cuz some of the low end amps performs poorly at low gains, like you said that there is a minor channel imbalance. so for what ever volume you are comfortable with regular listening, does the channel imbalance still remains? Thanks for your detailed reply and pardon me with all my questions. haha

1. I did not notice any whitenoise at 1x gain from silent all the way up to comfortably loud level (knob going from 7 o'clock at mute to 9 o'clock) with both Triple Fi and ATH E40 2. I did notice the imbalance at very lowest to around 8 o'clock in volume knob, present at both TF and E40 but right after that point I had no issues with imbalance.
I did have to slightly lower the input level to have my softest comfortable level past that 8 o'clock (currently it's around 9 to 11 o'clock for softest comfortable to loudest) and didn't have any imbalance since. I tend to listen to music at softer level than many others so over-amplification at the quietest level was my initial concern. Thank goodness this is 1x/3.3x not the normal gain.
I hope my two cents can provide better judgement in your purchasing decision.... To bias you even more with my opinion I really like how mine sound :P
Can anyone tell me if this is an upgrade over using my existing Asus Essense STX soundcard? Using to drive my Sennheiser 6XX and 58x jubilee's. If this is not much of an upgrade I was considering spending the extra for a Jotunheim or a Cambridge DacMagic Plus. Please excuse my ignorance as a noob. Trying to research to get a better understanding of what would best fit my needs. I am just looking for something better than my existing Asus Essense STX as I find it underwhelming. Using my headphones for both gaming and music and I sometimes still like to use my desktop Logitech Z-5500 speakers. I would appreciate any feedback or guidance.

Hey no worries. The Origen G2 is the current gen model. The G2 and the + have different DACs.
Canuckz
Xonar Essense STX? It might only grab off of +12V power supply. (O2 has +/-15V for reference - 30V swing rail to rail). So yeah, you'd get access to higher voltage potentials with O2 (which can add clarity even if you're not even close to using it). The tech in the card it self is pretty good but since it's inside your case it might be audibly affected (is it near a powerful graphics card?)
I wish i could test a sound card like that just to see how they actually fair vs the negative hype they get. I have audio boost 2.0 on my mother board which was pretty good but was at it's limits with 6xx. An amp helped with allowing for heavy use of a digital EQ (-9'ish dB pre-out). A DAC cleared up the faint hiss I could hear. I'd expect Xonar is better than this but maybe not.
I have read a lot of different things. Does someone have a definitive list of changes and/or differences between nwavguys o2 design and the mass drop variant? I believe at least one of the differences that I read were the caps. Is the gain issue fixed in this batch?
I have the HD58x headphones and would like to try a DAC/Amp with them. I had previously started focusing on the FiiO E10K but this O2 SDAC sounds like a better product. I would like to use this mostly at my desk but with an iPhone XS as the music source most of the time. I use my PC for Skype business phone purposes and may want to keep these sources separated. Can anyone tell me what cord I would need to use this with my iPhone? Some background: I am just entering the world of higher quality listening with the addition of the HD58x headphones. I am particular and have a number or other Sennheiser headphones of good quality but the 58x step is big for me. My music is ripped at 320kbps mostly and I am now re-ripping as lossless. Thanks In advance!

Thanks for the reply Eli35. I went ahead and purchased this DAC/Amp already. I'm sure it will be so much better than the on board sound of my PC. And now that I know what cable to get I'll give it a try with my iPhone as well. Also, thanks for the insight on 320kbps ripping. I will move any files I have below 320kbps up to FLAC or 320 depending on the songs value to me. But to save space I will continue to 320 for much of my music. I'm happy with the HD58x headphones and think that they sound better and better. And am getting more comfortable with these over the ear type headphones. Prior to these my favorites were the Sennheiser PX 100-II which are so light and comfortable And they sound very good too!
NicJohn
I'm glad to hear, good luck entering the audiophile world! BTW one of my favorite headphones are the Massdrop x Hifiman HE4XX, you could drive them with your new O2/SDAC without issues and they should sound pretty good. HE4XX are quite different from your HE58X, from driver technology (planars sound AMAZING, the speed of the driver gives much better texture to some instruments, you have to try it) to ergonomics (these are quite heavy and round-shaped, senns are light and oval, headbands are quite different too...), so they could be a nice second pair for your collection.
Too bad the RCA isn't preout.
