thanks so much. bonus novice q then: why does a Hegel H190 cost so much more than the Yamaha RX-2070? ie their amp power rating is approximately the same (150 vs 140 wpc); but the Yamaha has so many more features. ie at least on paper it appears to be H190 ++++ (more channels, plus video capabilities, multi zone, but also does Direct 2ch, has a DAC etc). Yet the Hegel costs 2x. What's the catch? Does Hegel produce fuller, cleaner or otherwise "better" sound? Similarly Naim, NAD, Parasound et al integrated amps also seem to be so much more expensive than Yamaha-caliber AVRs...
