I have a Silver Circle 5.0, and agree with your findings in my system as well. But how could you pick the damn thing up, it weighs more than anything in my system!
I will ask a dumb question on power conditioners
....what is the difference between a power conditioner and a power distribution unit ???? I saw the site for these here on Audiogon and I noticed that there are in fact two types of units being sold. 40 years in this hobby and I understand power conditioners....but what is the difference and what are each used for ????
