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 the Au24 + Au24se. Remarkable clarity and frequency extension; loads of detail in my system, and they seem flat across all frequencies to me - creating a very cohesive experience.
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?
