I have recently re-cabled my system w/ Tellurium Q Ultra Black speaker cables, and Black balanced interconnects. I upgraded from some XLO speaker cables, and BetterCables Silver Serpent balanced interconnects. No comparison, the Tellurium's were far superior. In fact, I've compared the Tellurium's vs Cardas Clear, and I liked the Tellurium Q's better, better bass, mids, and smoother (though still very detailed) highs. Well worth a listen. BTW, the rest of my system is Ayre DX-5, K-5xeMP, VX-5e and Wilson Sophia 3's.
