I also have a full loom of FMS cables, they replaced high end MIT and Purist Audio, and made a significant improvement. Their unique geometry and construction using thin copper wires with great insulation provided an improvement in high end detail, without being 'etched', or harsh, and their low end grip on the bass is outstanding. They are very quiet, and provide a nice overall balance to my system. They don't advertise, or get into the newest hype, but they just sound very good. Several of the reviewers, including Oster use the FMS cables in their systems as well. They rarely show up used, since their market share is small.
