I tried lots of older AQ, both LS and IC, all of them solid core copper. I do not like the LS-cables because they squash dynamics but only went to ~$25 pm, perhaps the more expensive ones are better.
I still use the Coral for my tuner, it tames unruly treble.
Basically all AQ-cables I tried smoothen and slightly roll off treble, make the bass more loose instead of tight, giving a warmer sound at the expense of dynamics.
Important is that solid core copper tends to age rather quick (a few years); appearantly this seems to be caused by microscopic tears in the metal, so don't move them around to much (but don't get overneurotic, and the cables themselves are well made).
I moved on to Kimber for my whole system, since I prefer the more open more extend SQ of these (8TC for LS, Silver streak for IC). Interesting how both brands for me represent the cablecompanies that have the most distict sound signature.
