Oh, and by the way, I did listen to Atom Heart Mother in SQ. It performed quite nicely. Better than Audionics? Not sure, I'm judging from memory, but definitely as good as. But you have to remember, that SQ is the Audionic's fort'e. But the surround Master has the added extra of a center and subwoofer channel. I like that because my center channel speaker is the same as the others. Not a cut down version designed to fit under the TV monitor. However, last night it was amazing in QS mode with Spirit's "Twelve Dreams of Dr Sardonicus" I also played Deep Purple's "Fireball". That was a good listen as well, but not quite like TDODS.
