It's pretty neat to see a couple of guy's still running their older Yammy 659's as I am. What a bargain this unit has been.
Still think this is one "clean" sounding receiver. I have upgraded just about everything else in my set-up, but this unit, and it surely holds it's own.
Have added an external amp to give push to new speakers.
The missing HDMI is fixed with a switch. Only the newer audio codec's are missing, but since I am not moving to 7.1, makes me wonder whether there is any benefit to a new receiver or pre/pro.
The corner trap thing sounds like something I need to investigate myself.
Publicspirit, it sounds like you have got some great advise from extremely knowledgeable people in this thread. Good luck with your upgrades.
