i use emotiva products and lonnie at emotiva might be a good source of an accurate answer. i recently switched from kimber to murrow audio cables and wires thruout my system and the improvement in sound is incredible. i also added isonode vibration control pods with great results. my opinion would be to look into emotivas erc1 and new cables if you havn,t already. i have the xpa 2 with erc1 and the usp1 with magnepans and velodyne subs. sounds very nice.
