Hi all. Just joining, have been going over this site and find a lot of useful information which is very helpful. I have recently just gone from 5.1 channel to 2.1, my main listening is music. My equipment consists of Anthem mrx 700 for t.v and movies, bryston bp25 preamp, anthem and rotel amplifiers to power Klipsch rf7ii, paradigm sub15, Klipsch rc64ii, rs52ii with the mrx for t.v and movies.
