Killer used integrated for

A used Yamaha A-S501 or 701 could be found used. I have the A-S701 and believe it to be great at it's price point ($750 new).

OP here, went with the open box Marantz pm6006. Price was great, easy breezy purchase from Music Direct. Received in 1 day. We'll see how it performs in my second system which uses my vintage ADS L710's (for now) and Sony BluRay/CD/Sacd player.. Thanks to all who shared their opinions. 

Look on ebay and craigs for older Peachtree and Rotel.   Like this

Hope you enjoy the marantz; they really play well and they have gobs of power.

mcondo, I'll add one thing. My son bought that same integrated. The way he talked, it was pretty sterile sounding out of the box. Sound improved the longer it was run. Take care
