Second the Jena Labs. They're the best cables, period, I've ever heard--copper, silver, palladium, whatever. The upper models are not cheap, but if you've got the system, they're more than worth the price of admission.
Great Copper Cables?
I have a VTL IT-85 (Mullards) with some Thiels and I get some minor excessive brightness....... I'm using PAD Museaus but one time I hooked up my backup bottom scale Audioquests and I lost some resolution but the tone warmed up nicely............ Any way just wondering who makes some of the best copper cables and which models?
