I have been looking to replace my old two channel Onkyo receiver with a new HT one. I live in a 655 SF condo with paper thin walls. Power is not a big concern of mine. Sound quality is. The manufactures I've been pulling my hair out over is: Marantz (SR5200/SR6200), Outlaw 1050, Onkyo (686), Pioneer Elite (33/35), Yamaha (1200). All of which I have found on the internet in the $500 price range. The receiver will be used for a home theater system as well as to power speakers in my bathroom and patio. For these speaker I will purchase a quality speaker selector. Even with the high end speaker selector I know from experience that a high quality amplifier will be needed. Also, do I need DPII? FYI, The speakers in the main listening area will be Definitive's (2006).
