General Sound Impression:
Got this for about $150 and have this laying around for at least 1 year and 6 month by now, and i only can say that these DAC do sound very nice,
Paired this little guy with a HD650 and i can say that this DAC have some very clear mids, with a nice sound stage and good layering. For me, the only downside from the sound, might be just that the lack of bass impact, but this can be covered by using some amplifier, so the problem is solved,
This Tube modeled DAC, is only about 12 cm long with simple USB input and 1/4 Jack Output, so this could be a very nice transportable DAC, Also this DAC have some quality build, with an almost full alumunium body, make this DAC looks quiet a premium item, it's just this DAC give a lot of heat issue, but this was supposes to be a desktop DAC so this shouldn't be a problem, but this is really worried me sometimes, as a lot of heat might shortened the life span of this item..
