In your review you said you preferred your new USB Dac when it was feed by a Trends UD-10.1 RATHER then when you let the DAC act as the sound card.This puzzles me. The UD-10 is a very low dollar device with a $2 chip that is actually intended to be used as a super inexpensive DAC. The Trends just uses this cheap dac chip (the PCM 2704) to take the USB input and convert it to S/PDIF.
So, you are saying that this $2 device does a better job of processing USB than the AQVOX?
Again... that really puzzles me.
I had a UD-10 connected to a MF X-Dac and replaced it with a Benchmark DAC 1 USB. Just for "fun" I tried the UD-10 with the Benchmark and compared the two unit's ability to act as a sound card and the improvement between those two devices was pretty clear cut to me. (Yes, I did have an outboard power supply on the Trends)
One more thing... the Trends outputs 16 bit/48K sample rate. Certainly the AQVOX, like the Benchmark does a much better sample rate conversion to 24 bit /192K sample rate.
