Killer used integrated for

I have a Mcintosh MA7900 that is another one to look at but they're not cheap.  

+1 another vote for the Marantz PM Intergrated line. I sold my brother my older PM 8005 when I moved up to the Krell K300i and he loves it with his Klipsch speakers and SVS subwoofer. 

only one person mentioned Rotel. so, here is another vote for it. I prefer it over all other amps I had (Nad, Marantz). 

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.
