I did a a/b test including phase comparisons and latency comparison, I recorded few of my synths and the output from my dangerous.
- When I recorded my tr8s the sounds was cleaner and a bit more fat, you only can hear this if you have a good pair of speakers or a good headphones. But Yes, I recorded two takes, one with the UDG and a different one with a standard usb2.0 cable, new I reversed the phase and boom...sound was slightly different.
I didn't trust too much about usb cables (I know audio cables plays a huge roll on the sound quality).
A second Test I did was the Latency between my moog GM and my computer. the standard usb 2.0 cable had a bit more delay. Believe or not, It helps you to get better takes.
I gonna get few more for the studio.
