Bruce, Stuart, Mark,
Great replies. I've been a bit lazy, and haven't used my RS soundmeter yet I merely used the Denon microphone to calibrate the receiver. I really need to purchase either the Avia or Digital Sound Essentials DVDs and calibrate the receiver through the DVD player (and adjust the center channel maybe).

Mark, you are the man! I have an understanding of the underlying concept behind this issue now.

Thanks again guys.
