I urge you to try the Triode Wire Labs speaker cables. I've been through many brands (many much more expensive than the TWL cables), most recently the Jena Labs Twin 19s, Kubala Emotions and the Auditorium A23s.
In my setup, none have sounded as good from top to bottom, nor as completely natural and musical as Pete's TWL cables. Many people have tried and enjoy Pete's various outstanding power cables (I have a number of these and love 'em), but I've begun to believe that his speaker cables may be even better!
Plus, Pete is one of the nicest guys in the business!
