i'm surprised that clayton has discontinued production of these cables. they are -- in a word -- superb.
over the last few weeks i've had a chance to compare them with two other sets: a pair made from duelund wire, and a pair of wireworld mini eclipse 6's. all three sets have had ample break-in time.
i won't say that the quantum cables make a jump-out-of-your-socks difference, but i will say that they *are* audibly superior to the others.
bass is deeper and better-defined, midrange is broader, deeper, and more natural, and the highs are just ... sweet.
