I'm using the Symphony speaker cables in a vertical-biamp configuration with Jena's Dreamdancer cables, and I have to second the opinions of Bob and Tireguy. They are indeed great cables. What has impressed me most about them is their background silence and effortless way with macro- and microdynamics. Jena's premium stuff is top-flight all the way, but the Symphony may be their biggest bang for the buck. In the right system it's magical.
