I listen to mostly jazz, blues and the like also and for what it's worth, I'm currently using the Double Helix cables in a secondary (bedroom) system with my home built Welborne Laurel II X 300B SET monos and vintage Tannoy Monitor Gold 10" drivers in home constructed cabinets and I absolutely love the result. Also, about as high as you can get in terms of their WAF aesthetics...if such means anything to you.
