I am currently considering upgrading from Denon 2309 to 3D capable AVRs like Denon 2311/3311 or Pioneer VSX-1020/1120. My dealer has asked me to consider Pioneer VSX-1020 before I finalize Denon '11 series. Online manual of Pioneer VSX-1020 states its power output at 110W x 7 (1kHz, THD 0.05% @ 8 ohms) and 80W + 80W (20Hz - 20kHz, THD 0.08% @ 8 ohms). Whereas Denon website states on 2311, I quote, "The equal power amp design features 7 discrete power amp circuits, and each channel is rated at 105 watts (8 ohms, 20 Hz to 20 kHz, .08% THD)." Unquote, does this mean Pioneer VSX-1020 is 2-channel amp driven at much lower RMS power compared to Denon 2311? Will this have real life issues while playing heavy 5.1/7.1 channels, all driven together? Could anyone kindly recommend an 3D capable amp (with ARC) limted only to Denon, Pioneer, Yamaha brands, that would make my RS6 speakers' really shine to their potential? I would like to limit my budget to GBP 1,300 equivalent. Many thanks for reading and your time.
