If you're worried about price, why don't you just buy a Bob Latino M125 monoblock (120 watts each) pair for more than $1500 less than it would cost you for the Mac? And you can save another $700 or so if you buy it in kit form and build it yourself. You can't begin to get that kind of satisfaction from buying any commercial product.
