Jools, tis cool, you could ask Henry about the Au24, he's been trying some out over the last 2 or weeks

Well, blind is fine, I would like to come down and have a play, if you so wish, The Lavvy is a good amp, and responds to various stimulii   

If we make no difference, then cool, least you've had a bit fun trying

The size of the cables doesn't neccessarly matter, the AU 24 is amere 4mm thick, (example).

How far apart are you Speakers?, are they on concrete/granite plinths? how many I/c's do you use? p/leads etc? Wm
