I have an ultimate receiver and use it to power 3 pairs of speakers that are mounted in the ceilings in my house (Party Mode). The other two pair of in-ceiling speakers (family and living room) I run a pair of M-500ts for off the preamp outputs and and M-400 for a pair of small subwoofers (actually AR-3a 12" woofers).
It should sound like it isn't there!
There is a difference between hearing and listening...
