Jason, that's an interesting idea. John, if I use a 600 with a 400, can I get the tightness from a 400 and the depth, power and transparency from the 600? And I have a Sony too so maybe I can use that as well.

One other question. In your experience, how many subs are daisy-chainable from the sub output of a receiver?
