every brand of amp and wire have different advantages and disadvantages, need to match.
By the way, I used AV Amp to listen to CD before, I thought its OK already. However, after I changed to 2 CH. amp for music, totally 2 worlds! If you wanna listen to music, just try 2 CH. amp. You know, the Video part of AV Amp really affects the pure sound quality. 2 CH. amp is not very expensive if you choose a not-so-high-grade one.
