I have been reading the forum as a guest since I got into HT a few months ago. I started with a Denon AVR 1613 and (2) Polk Monitir 70's, (2) Monitor 40's, and a PSW 505 12" sub. I love the system I have, but of course now want more. I plan on staying with a 5.1 setup, but exchanging the Monitor 40's for another set of Monitor 70's and adding another PSW 505. It is my understanding I will need a more powerful receiver to power another two Monitor 70's as I like to listen to my music pretty loud in multi channel stereo. I have been thinking about replacing my 1613 which has a 75w power rating with the Denon AVR 2313 which has a 105W x7 power rating and only using the five channels and two sub outputs. Will this receiver be enough to power the speaker setup I want to run? Thank you guys for your expertise.
