Here is a question for you guys. I have the Denon 2809 and am using it as 5.1 with the extra 2 channels as a Bi-Amp for the RTiA5 front L/R. The wattage per channel is 115. I am asking because I am thinking of buying a Rotel RB-1080 with 200 watts per channelx2 for the fronts and dont know if that will be an upgrade? My A5s are very good, but I feel they are still lacking. Would the upgraded amp help with imaging/sound quality/dynamics, or should I look to the a9 or something else for my speakers ? Do the A5 speakers have it in them to be great ?
