used McIntosh should definately be considered. I like the Blue Circle too although it can sound a little thin. Like-wise for Bryston. McIntoshes can be had for a good deal on ebay since there are many of them around (50 years you know...). I just love all of mine - the recent ones having the most imaging and 3D effects I have ever heard and superb controlled bass with a real goose-bump-inducing midrange. A little Classe would be nice too - there is CA100 on ebay right now. I used to own Krell but not anymore! Good luck
