Speaker cable suggestions


I'm currently using the latest version of Townshend Audio EDCT Isolda but feel it's slightly restricting the performance of my Gamut M250i mono blocks.
I have a shortlist but would be interested to hear your experiences with speaker cables that you have found exceptional.

Thanks.

I'll second (or third) ClearDay Cables. They replaced far more expensive wires in my system (I realize this means little to you, but I see this mentioned often, so there ya go). Additionally, Paul is truly one of the good guys. He's an absolute pleasure to work with and will send you a pair to try in your system with no commitment to purchase.
Thanks for the continued suggestions guys.

Srosenberg, which cables did you replace?
@ Infection: Acoustic Zen Satori... I prefer the ClearDay cables to the AZ's by a considerable margin. In fact, I prefer them to all the cables I've tried previously. Of course YMMV!
