If you are looking for multi channel amps, maybe you can find a Sherbourn PA-7/350 for sale. They offer 350 watts per channel for seven channels which should be plenty to drive any speaker. I own eight Sherbourn amps currently and they are built like tanks, and very reliable.
if looking strictly for stereo, I currently run Emotiva XPA-1 monoblocks with 500 watts each into my KLF-30's. If you can find those you would be fine, however they are only single channel amps
