I have an ADI-2. I was previously using an M-Audio Flying Cow. I was under the impression that the sound would be greatly improved by using the ADI-2 but that has not been the case.

#1 - if the input level gets too high, the ADI-2 simply shuts down, and then resets itself. Huh? Perhaps I want the sound of overdriven converters. Who decided how high I can go input-wise? This is using the SPDIF out of my HDSP 9652 to lock the box or without using the SPDIF clock. The Flying Cow, OTOH, accepts whatever input level I throw at it.

#2 - I get clicks throughout my mix when I mix through the ADI-2, clocked or not clocked (analog in from an analog mix desk). None with the Cow.

#3 - Where is the great sound? I cannot hear any difference from the Flying Cow. Shouldn't the difference be noticeable? Even the guy who designed the not-so-new anymore Cow told me that the sound would probably be better using the ADI-2.  When I switched from my Delta 1010's the RME HDSP 9652, the difference was noticeable immediately.

Is my ADI-2 in need of repair?
