I recently convinced my wife to let me get a new receiver. I bought the vsx-1121k for $400 during black Friday. Its my first real receiver. I'm currently running with monitor 70s, cs2, and some small bookshelf speakers for the surrounds, and a Sony sa-w3000 sub. I've got a bunch of stuff i'm going to be selling so I can spend more money on my system. I do about 60/40 on ht/music. I'm trying to decide whether I should get an amp for the front or new sub. I haven't decided on a final budget but i'm guessing no more than 500 (really wish I could spend more). Any words of wisdom?
