The DAC chip described on the xDuoo TA-01 product page is WM8740 and the description on this drop says the DAC is a WM8470. Is this a typo in the description or is the Massdrop DAC shipped with something else? Is the DAC chip we're getting less than the standard offering? The Astell&Kern AK120 has a Dual Wolfson WM8740 DAC and not a WM8470 DAC.
The Massdrop DAC typo (maybe) in the product description page and the Trojans discovered in the driver download from the xDuoo website have forced me out of this drop. Bummer as I purchased a tube for this device today.

PathworksJust because the company doesn't list out the long brand name, doesn't mean it's different. A lot of people would already recognize WM as Wolfson, PCM being Burr Brown/Texas Ins., AK being Asahi Kasei, etc.
If you're doubting whether it has dual chips or if it's even a WM8740, here is a picture of the internal:

Also, NOD32 and Malwarebytes came out clean on the driver. 446 files scanned with 0 infected objects.

That's a nice stock photo of a card and that does not convince me that it is actually taken of the product shipped on Massdrop. If the ad here was accurate maybe I wouldn't have raised the question about the card (swap). If the card is the 8740 then why does the ad say 8470? It says the same number on the other xDuoo devices advertised on this site.
I use Malwarebytes Pro (paid version) and that has the malicious site blocker code in it.
I scanned the downloaded archive file (.RAR) with McAfee and it popped up with the detected trojans.
I'll definitely buy this if I feel confident that the manufacturer isn't gut swapping to offer their product at a lower price.

PathworksWhat's more likely to you ?
That Massdrop made a typo in the specification.
Or
That WM8470 DACs were built (since they don't currently exist), and put into custom XDuoo TA-01s built just for this drop.

TigoleGood point. But I don't know there aren't any 8470s made by Wolfson. Are you certain they aren't made? If so, great -- then the community knows its a typo.
I'm still concerned that the manufacturer's site is blocked by Malwarebytes and that the .rar download has 2 embedded trojans. Aren't you concerned about that? I don't feel comfortable having to deal with this company if they send me a defective unit.

PathworksHere, let me try to satisfy your tin foil covered mind.
Cirrus Logic owns Wolfson Micro:
http://investor.cirrus.com/news-and-events/media-center/news-details/2014/Cirrus-Logic-Agrees-to-Acquire-Wolfson-Microelectronics/
Now, go to http://www.cirrus.com/en/ and search for 8740 and notice that you'll get results. Now search for 8470 and notice that there are no results.
As for the trojans, note that "Artemis/*" is a generic result from McAfee, for when its heuristic engine detects behavior that might be suspicious. As someone else mentioned, their own antivirus scans showed nothing. I scanned that download myself with MSE, and didn't get anything either.

Tigoletin foil? was that necessary? I'm just reporting what I find that looks suspicious.

PathworksA google image search would've pulled out where I found the internal PCB, but since you went ahead and assumed that it's a stock photo without doing a search yourself (seriously?), here's a direct link to the entire disassembly. http://speaker.yesky.com/pics/162/35267662_16.shtml
As for malicious code on website, Malwarebytes isn't the greatest software you would rely on as a firewall, not even Google Chrome's blocker
And just like McAfee garbage antivirus, it was very likely a false alarm. In case you're going to wonder on what did I base this claim on...below is a link that shows the number of false alarms on the antiviruses out in the market. MS Security Essentials being 0, ESET NOD32 having 1....oh look, McAfee with 10. http://www.av-comparatives.org/wp-content/uploads/2015/04/avc_fps_201503_en.pdf
So yeah, this product has been on Massdrop more than a few times already. I was one of the few to buy this here when they did the first drop and even helped them fix the specs they missed out on (RCA doubles both input and output instead of just input). If the malware was such a serious issue that existed, this would've been picked up ages ago.

the-goldfishThanks for setting me straight. I'm sure if people were having issues they would have said so by now. I've moved on.
