I have just taken delivery of a shiny new avc11sr. It replaces my old Sony 940 and the difference in quality is beond belief. I know it cost a shed load more, but if people are considering this amp then just buy it, its great. My speaker set up is as follows: 775 Fronts 77c1 Centre 773 Rears M52's Rear back REL Q400 Sub Would I be better using the 773 as rear backs and using the m52 as the rears? Any thoughts/suggestions welcome.
