Well, my needs have changed. I set up the new flat screen, tried hooking up my existing stereo, and really didn't like the results (layout of the room, speaker placement, messing up my usual routine regarding listening to music, and more). I think instead I'll simply go with a Zvox to place underneath the flat screen - reviews are good, and there's been a large price drop, though some reviewers imply the device is mostly to help the hard of hearing, which gives me pause.
I still want to replace my aging Yamaha integrated amp; am looking at Marantz, Denon, maybe NAD and Onkyo. I want to spend up to $500. Any suggestions would be most welcome.
