I don't think your requirements is a difficult list to fill at all. The answer is a REL T-1 available for $499 brand new, comes in a cherry finish and has a reputation of being more of a musical sub than HT. Plus, REL recommends the high level hook up from your amps speaker terminals to the sub. They even provide the speakon neutrik cable that makes integration a snap. If you check Ebay you can readily find sellers at this price.
I have a Rel T-1 hooked up to my Vienna Bach Grands in this manner and am extremely pleased. Bass is fast and tight easily keeping up with musical content. Hope this helps.
