I bought a Toshiba 57" WS HDTV (57HX81) about six months ago and I haven't purchased a surround sound system for it yet. I've been looking into getting one, but I don't really know that much about them. Anyway, after lots and lots of research, I have narrowed my receiver search down to these three: Sony STR-DA4ES Harman Kardon AVR-525 Onkyo TX-SR800 I would like to hear everyone's opinions on these receivers and which one they think is the best. Right now I am kind of leaning towards the HK receiver, because of all the good things I've heard about their receivers. Their wattage ratings are supposed to be super conservative and their receivers give out twice as much power as similar competing receivers. I know you probably want to know about the speakers that I'll be hooking up to the receiver, but I have not decided on that yet either. I think I'll be getting JBL's or Polk's though. I'll start a new thread on this later.
