Thanks for the kind comments everyone... system sounds nice 75% of the time. I do like the BR2s don't get me wrong but they are now the weakest link.. I feel they don't quite have the refinement to tame the (foward and detailed) cyrus sound.. the system can edge into brightness with some recordings. At any rate the BR2's are "borrowed" from my BR AV system downstairs (BR2's, BR1's, BR CENTRE, BR SUB) so I won't be selling them.
Also on the lookout for a second-hand pre-vs2, having heard that a dedicated preamp sounds a fair bit better than using the 6vs2 as pre. Also I'll be able to sell the integrated at that point to recoup most of the cost.
Will definitely try plugging the 6 power straight into the wall (although it's over 4 metres, so the cable will have to be a cheapy)... have heard about conditioners "strangling" the power sections before... although the system is definitely not short on dynamics or punch.
