I agree with RGD. They need a TON of power. No integrated (at least in that price range) is gonna' do it. The more power you feed them, the better. I had spectacular results with an Acoustat TNT 200 (200 wpc MOSFET) and a Sonic Frontiers SFL-1 preamp. My recommendation would be to buy some "affordable" brute force, such as a Hafler, Perreaux, old Bryston, maybe even Rotel or Adcom and then buy a decent preamp. It's been my experience that they're not all that picky about the amplification provided that there's plenty of high current.
Down the road, you might want to think about a Sunfire Signature amplifier (600wpc). I know that these are very contoversial, but that's what I heard drive the Solos when I first auditioned them and it was phenomenal. I don't know how the Sunfire sounds on other speakers but I can recommend it for your Solos w/o reservation.
Good luck. You've stumbled across what is probably one of the greatest bargains to be found in the used market.
