An older Krell, like a KSA-250 would sound great. However, you have to be a bit careful when buying these used, as they are getting to the stage where they will need their caps replaced soon, if they haven't been replaced already. This will probably set you back $1000-$1500. If you can find one that has had it's caps replaced within the last few years, jump on it.
