Hello Bigsam2.
It has been my experience that choice of cables is as serious a decision as choosing components. I receently assembled a system around a BAT VK75 SE (75 wpc) SET amplifier and Wilson Sophia speakers. The Sophias are the least expensive and least efficient speakers in the Wilson line. They are great sounding speakers but they still require careful system matching w/ associated gear, including cables. The Wilson speakers are known for throwing a very sizeable soundstage. I did audition a number of products with these speakers (e.g. Acoustic Zen, Transparent, Synergistic, Analysis Plus, Kubala Sosna,and Nordost). They all had thier sonic merits and deficiencies. I ended up going w/ the Nordost Valkyrjas. Although the Valyrjas were not perfect, they seemed to be one of the only cables that did not compress the size of the sound stage that the Wilsons are capable of delivering. The Transparent audio cables were very detailed as well as very transparent but were among the worst offenders in terms of compressing/shrinking the sound stage when hooked up to the Sophias. Please keep in mind that these were the results heard with my associated equipment. The Nordost Valhalla is a superb and even costlier cable. It definitely allows more of the musical detail to come through than the Valkyrjas, but still there may be trade offs. In my system, the Valhallas seemed to rob the Sophias of some of their bottom end. Higher price does not always translate to the best component for a given sound system. So please keep in mind that sonic results with cables are very system dependent. I believe conventional wisdom would have it that you choose the speakers before you choose the cable. That doesn't necessarily mean the upgrade path you have chosen is unreasonable but the speaker cables you seem to be considering are a costly investment and you need to be careful.
