So, now that I've got my first real job since leaving college a year ago and a steady income, I've decided to kick the $250 Onkyo HTIB to the curb and upgrade to a decent starter system. I'm really only looking for 5.1 right now since my room is small (looking to move into a townhome in the next 1.5-2 years and these will be coming then). So far, here is what I've purchased: Onkyo TX-SR606 (checked out one in store for heat and humming, didn't notice much of a difference between this and my current receiver). 2x Polk R50s for my L and R speakers 1x Polk CSi25 100' 16 AWP Speaker Wire Currently, I'm having trouble finding either Polk's R15's in Cherry, or the R150's in cherry as I'd like either of those for my surrounds. Worst case scenario, I pick up the R150's in black and that completes the setup for speakers and For my subwoofer, I'm completely stumped. I'd like to get the SVS 20-39 PCi, but is that going to overpower the rest of my setup? Do I need to look into things like pre-amps? Other equipment to help keep things powered smoothly? Primary use is movie watching with Blu-Ray, Sports and Video Gaming. The room is approx. 18'x18' where this is.
