Any idea what the claimed sonic differences the manufacturer states, or what reviewers / users have observed in terms of sonic differences?
From the Devilsound website, concerning the changes from v1 to v2:
◦Increased capacitance on power supply lines, with fast tantalum capacitors and "flip-type" ceramic bypass capacitors.
◦Revamped power implementation of the USB receiving chip (PCM2706) results in additional jitter reduction in the recovered digital audio signal.
◦To accommodate these changes the enclosure is slightly large than the previous version, however, the connecting USB cable is thinner and has strain relief.
◦Enclosure < 2 cubic inches
For v2.1, they just cryo'd it. FWIW, I'm using a v1 in my computer setup, and I think it sounds great, very natural. $165 is a steal. As for sound differences between the old and new ones, I've never seen a comparison.
