Way under your $400 budget, if you can find one. The only downside is if you use an external amp, you can't use the "Pure Direct" button (not sure that's the exact name). I had that hooked up to a pair of Paradigm Studio 20's V3 in our bedroom and it was fantastic. Unfortunately, the wife isn't a fan of "ugly electronic junk" and it now sits in my garage
