I've had the 422/S8 system for about 2 years now and have been extremely impressed with the quality of sound for home theater but I'm wanting to use them more for music now and I've always felt the low midrange (80Hz - 150Hz) on this system feels a little empty.  I'm considering upgrading to the 532s on the front cos I'm sure this will ...

Two questions really. First, is this a reasonable combo for a 5.1 system? Im considering using the 422's as my fronts, the 422 C, the 534's as my side surrounds and the S-8. Secondly, could I drive this system with a pioneer 1015tx or the new jvc702? Any suggestions would be greatly appreciated. Thanks!! Julius

I got a 422/S-8 HT compact system recently and paired it with the Onkyo TX-SR602. I notice a hum coming out of the sub when I turn off the receiver. Am I supposed to turn-off the subwoofer power switch at the back everytime I turn-off the receiver?
