WM - lets hear what the system is so we can discuss this finding properly rather than just stirring the pot. As you havent really answered my question I assume it was not supported on the correct support. Give me the info and I will make a judgement about whether I think there is a possible flaw.  A wow factor for any system isnt just a factor of the source - every link in the chain has to work. So lets get it out in the open.

SM - the lagrange is better than the balance, also you havent actually heard my system... just as you havent heard the S7 and BL on the correct support. Half of it is diy so you have no idea how revealing it is (which it is). Have you heard pmc speakers or bryston amps? In fact if I am correct then you havent actually heard the BL at all - so any of your comments seem to be based on rather scanty evidence. Have you actually heard the sme 30 or yorke? I want to make sure I have understood you correctly. I think if your friend had used the correct support then he would have made a different purchase.

Anyway this is all rather besides the topic of the thread which is about active vibration management.
