I saw there was another thread, so I posted there as well but...

@ProtegeManiac makes an excellent point, a USB Sound Card implements DSP into it's digital output that is then fed into a DAC, having this unit function as both a digital source and DAC seems to limit some of that functionality. I frankly, like that it's able to fit into a PC case, makes for a much cleaner implementation into a system, but the inclusion of Analog outputs on the rear side with the USB Input means if I drop it into my Case, I can't quite use those outputs any more. Would make more logical sense to include ALL analog out's on the front facing side, so when I install it into my PC I have access to everything. Thankfully you guys are preferring that we loaner recipients use it stand alone so that won't be an issue to us...
The lack of SPDIF is also an interesting choice, but given the $299 price tag it makes sense. This is an all in one unit with a mixture of functionality and a changeable tone or frequency response via the Op Amp rolling, so to use a compromised digital input in exchange for an adjustable frequency response at this price point... is ok imo!
Another competitor in this price range is JDS Labs The Element, that all in one unit is also missing SPDIF in, but their stand alone dac the EL Dac does have SPIDF in and it's $250 by it self vs The Element at $350! For $100 more I lose SPDIF input but gain an amp, again for an all in one unit in this price bracket that seems like a fair trade off.
It's obvious that the target audience here is not us as audiophiles, but rather audio quality conscious gamer's and streamers. An thankfully, there are many of us who fall into both camps. Lovers of audio and active gamers/streamers. Though how/if it'll work with existing DOLBY DSP viz the USB In is pretty important, hopefully the drivers will allow for that compatibility.
