I replaced my Kimber 8TC with JPS's entry level Ultraconductor and found the improvement noticeable - a greater sense of openness on all music, along with very well defined bass, involving midrange and clear but refined highs. The music seems to emerge effortlessly. I like the sound much better than the Kimbers and still use the Ultra in my 2nd system with no impulse to change; they are very satisfying. I believe the Qs are a level up from what I have.
BTW I am also using the Superconductor Petite biwires on my main system and love them; they reveal every upstream upgrade I make.
