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.

Clear Day Cables - find them neutral , no harshness, good balance across spectrum
Kimber Select KS-6065 would be nice. I use the older KS-3035. Both are a copper/silver hybrid. In my system: very nice extension, detail, tone, and harmonic balance.
I've found the Merrill speaker cables to be very good and not just for their modest price (at least by audiophile standards). Merrill has great customer service and I'm sure has a trial period.
Thanks Facten, Reynolds853 & Wcheng2...all suggestions are very helpful.

I had a reply from Alex at WyWires who said any slight harshness I'm experiencing is the characteristic of the Tannoys...I have to say that is not the case.
The Audience's Au 24 and Au 24e are smooth and transparent. And it's remarkable the way they lower the noise floor.
Plus the prices have come down since the introduction of the Audience Au-24 SE.
