I'm one hundred percent confused about RMS watts/channel with Surround recievers ... I have a Yamaha RX V473 which is rated at "105 x 5 channels". I've read other places that when playing through just two channels it is much more. When listening to music I set it to 2 channels only, for movies I like to turn on the center channel so I can hear what characters are saying :-). Is this nonsense or my reciever push much more power to two channels than it would with 5? How does this crap work?! There is so much conflicting info on the net. Is there a good idiot book for this stuff?
I'm driving a pair of Polk TSI-500's with it and although it sounds great when cranked up a it, when played at low volumes softer parts of the music are nearly inaudible (mainly a problem with classical recordings). I did not ever have that issue with my Monitor 5 Jr's - but needless to say the TSI-500's sound a million times better. People say this is because my speakers are "under driven" with this reciever.
If I were to hook up a quality 2 channel amp/preamp to these speakers, with a powerful amp, say 200 watts/channel, what difference would I hear? I don't neccessarily want it louder - the Yamaha can get them VERY loud with no clipping - louder than what I can reasonably play with the other tenant downstairs. I would like in any case a surround system (just for the center channel) if only because I frequently watch TV shows or films on the same setup.
