This morning I have tried A/B testing the Aqvox versus my old switch, using AIR 3.0.4. I had two reasons for doing this, firstly some previous posters where asking about the potential for the Aqvox to improve sound quality with AIR. (@brit / David, as I recall, there may have been others) The second reason was that I figured that I am using the switch in front of a microRendu and Mutec MC3+USB. This is a combination that should provide isolation and re-clocking, so perhaps any short comings in the old switch were somehow being masked by the good work of the Mutec. So in other words, I was expecting it to be easier to discern the good work of the Aqvox via AIR. I had intended this to be a fairly quick and straightforward test, but I ended up spending more time on it than I had expected, with a lot of rapid A/B swaps on particular sections of music. The reason I did this was because on a couple of occasions I felt that the old cheap TP Link switch was best! There was still a very vague feeling that the sound stage was a little better with the Aqvox, but I really cannot be sure. I have to be blunt here, in my view the Aqvox would be a complete waist of money to use with AIR, spend it somewhere else!
