Steven, if you haven't been driven away screaming, Emotiva has frequent sales. I got my XSP-1 for $769. Just keep that in mind if buying used. The stuff is built like tanks, and very large. It can take some planning to make room for. If you do decide to give this a try, a used USP-1 might be safe. If you don't hear an improvement, you may not want to go beyond that. It just depends on how concerned you are about money. There is a 30 day trial on new gear, but I don't think that gains you much unless it is something you clearly end up not wanting.
