OK, old thread, but I thought I would add my two cents worth. I bought a Durio Sound Pro V5.0 "a while back". Never a complaint, loved the detailed sound. I accidentally dropped it moving equipment, and damaged the DC power jack. Swapped it out with "whatever" I had lying around on the bench. An Asian, unbranded, "ES9018K2M". I had previously upgraded the budget supplied Op-Amp to a OPA1692. Seemed "OK" sounding, nothing great. Vinyl sounded much better than the Asian DAC. Once again re-configuring my system, I saw the the unused Durio Sound Pro, and remembered it could be powered with an AC transformer instead of a DC supply, because it had a high grade power supply circuit built into the Pro version. I outfitted it with a 9 Volt 1.1 Amp AC transformer. I hooked it up again to test, and it "blew my socks off." High Def. Audio Files are so detailed and dynamic, I am once again enjoying critical listening. My guess is the inter-modulation distortion has dropped quite a lot, because all of the instruments are very well defined again. This is not the comparison you asked for, but it is a vote for Durio Sound as a great DAC.
