Just my opinion here.

I love my 563a....for how much it costs and what it adds to my system, it was a bargain.

BUT, if your receiver/pre-pro can not do bass management on the 5.1 analog interconnects, I really advise against it. On the 563a, when the speakers are set to small, the crossover point for SACD is 120hz, and for DVD-A is an astronomical 200hz!

The reason for this is because the unit was designed for the HTIB market, and the types of systems that we have put them in.
