I want to upgrade the speakers in my current home theater, and eventually upgrade my reciever. I need to know what speakers would work the best with my current Sony STR-DE875 reciever and also offer expandability for my future 7.1 reciever. I am currently using Sony MF 315s as my mains and the Sony SR 305 center and surrounds, as well as a Sony SA-WM40 subwoofer. I am planning on buying a Yamaha 7.1 reciever within the next year or two.
My room is 14'x15' with 9' ceilings and wall to wall carpeting. I use my system for about 50% music (alternative rock, classical) and 50% movies/tv.
So what speakers would be my best bet? My budget is about $6-700 and I am planning on buying the speakers from a reputable online dealer (whichever one is cheaper). Is my current Sony reciever efficient enough to power decent speakers? Should I also replace my subwoofer? Or should I buy the reciever first and wait to buy speakers when I can afford them?
