Im on the verge of buying a homecinema system, but im still not sure which AVR amp I should buy for the TSi500 speakers. I have some on my list though, like Denon AVR-1610 or Pioneer VSX-819. My living room is 20m2 area. Center speaker will be CS10 and backs TSi100s. I also heard H/K amp on TSi300 but the bass wasnt that good. Any suggestions?
