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.
I have a Objective 2 + Objective DAC combo for sale. The Amplifier + DAC combo is made by Mayflowers Inc. A 110V US wall adapter is included. It has the following configuration: - gain 1x & 3.3x. - uses 6.35mm headphone jack instead of the default 3.5mm - comes with a DAC RCA line output  - power jack located at the rear panel instead of the front panel  - comes with aluminum volume knob instead of the default rubber one I will sell for $190 + shipping.

I will be selling my O2 + SDAC if anyone is interested.
Anyone know how to connect the google chromecast audio to o2 sdac combo,i would like to use the dac portion(by massdrop) then to the massdrop jbl lsr 30x speakers? Any help would be deeply appreciated! Example any type of wires and how to connect them?
I was excited to test mine out immediately but when I plugged it into my laptop, I found out I couldn't hear some channels. Is anyone else experiencing this problem? https://www.youtube.com/watch?v=UOxkGD8qRB4 Can't hear the rap parts. https://www.youtube.com/watch?v=VHrLPs3_1Fs Vocals sound so far away. This happens whether I use it as a DAC or just as an amp.
Anyone have any recommendations for a replacement power supply? Mine has started to hum and is getting progressively louder and louder. Thanks.
What does the power button do in the "on" state with the red light? Does it mean the amp is on? Is the DAC always active?
Nicholastran213
The red LED lights up when amp section is turned on, as for the DAC section there are no indicators. The power adapter is only for the amp section, the SDAC is USB powered.
OpasTanti
Thanks for the clarification!
Hi, has anyone experienced the dac suddenly doesn't function? Very intermittently problem. I'm not sure is it because of windows 10 or hardware problem.

Yes it happens often. If you find a solution let me know.
LFRuiz
This is probably the best solution after trying everything 1. Make sure USB is not suspended. 2. Turn of power management for USB 3. If all else fails, stick it into another port. It will register as 2-DAC. So far it has been working well.
Anyone else buy with a Oct 22 ship date? Mine still hasn't shipped

They ran out of stock. Contact support and ask for refund. This sucks bc I ordered a new Power Supply from JLabs and it's useless for me now. I wish they'd stop the drop when they sell out of an item not after.

Whatttt. I also bought a 110V power adapter. This is unacceptable, they should not have accepted the order if they did not have stock.
Can someone sell me the Purple Heart box sticker with burgundy lettering and white lines?
BigSome
Both will work just fine, but if your mains gets low(under 230VAC) then the 15VAC might be the better option.
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.

Could you explain how to "uninstall power management usb system"? I'm on a mac
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.

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 ;)
