I also have a Cambridge cd4se (w/Cambridge C500 preamp, Belles 150A Hot Rod, & Magnepan 1.6qrs.) Recently, I purchased the Aurex mat and cannot say that I'm all that impressed with it. On SOME discs, I could hear a slight improvement, on most, no difference. The mat is very thin and flexible and assumes a definite warp as it gets warm inside the player. I've had it get stuck inside the player when the drawer opened and then had to fish it out with tweezers. Because of that, I'm reluctant to continue using it.
