Curiousgeorge, the Odyssey Stratos (truly an overachiever at its modest price) would be a good choice, I have used one with horn speakers with great results. The other recommendation for a Mcintosh should also be considered as it tends to lean more towards a warmer sound. Right now I'm using an Onix integrated amp and I like its warm but detailed sound.
