Used Which amp for B&W 802 Matrix series 3 around or under 1000?

I just bought these 2 speakers and I am looking for decent used amplifier (audiophile if possible) for them under or around $500 - $1000. I know they need power. I like pop and classical music. I have an Infinity subwoofer. I don't want surround sound, only a decent stereo amp.
I have my old Onkyo Tx SV444 and I would like to upgrade.
Thanks so much!


Exposure 2010 S2 frequently comes up used below $1K. 

Or you might luck upon a Roksan Caspian M2. 

You are the best guys! Any more recommendation? I mainly looking on ebay. Is there any other reliable place look for a good amplifier?

Go to hifishark — they list used equipment from all major sites including A’gon.  A further benefit is you can see what past equipment sold for so you can get a good idea of a fair price range for any product.  Happy hunting!
