I'm looking to upgrade my Dolby PRO Logic receiver (Sony STR-DE345). I just got a new DVD player after spending a few weeks reading reviews (Panasonic RV31). My friend works for Sony, so I'm kind of partial to them since I can get a good deal, but it's not completely necessary. I'm looking to spend around $250. I looked at the STR-DE675, 845 and 945, but the reviews I've seen aren't that encouraging. Any suggestions? Thanks!
