Being as how conditioners have already been brought up;here is my nickel's worth. I owned the CJ Prem 5 monos. Had them a year before I tried the Audio Magic conditioner--This is both amps into one A M unit-- It was like my amps were on steroids. (Read,more dynamic etc.)More recently I bought the DeHavilland Aeries g. monos. I listened for 3/4 weeks before trying a conditioner--(a no,no,says the factory) I swear it was like I had just upgraded to twice as good a pre,or something similar. This was now an Adept Response conditioner. When I talked to my dealer and Kara--they hated me.This was a difference Hellen Keller could have heard.(Sorry, I have to give an "over the top" reference.)to make my point.
