Great Copper Cables?

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.

Only a woman could design cables like Jena's...

Going up in price and quality: Au24, Nirvana SX Ltd, Virtual Dynamics Master and Revelation Series. Can't go wrong with any of these, just depends on your ears and wallet!!

Audience Au24...
and my personal favorite that I've heard but have not yet obtained for my system...
Atlas Navigator All Cu (simply a stunning copper wire that provides the sweetest high end and the most realistic midrange ever!) The atlas cables are hard to find in North America, but are readily available in the UK. It's worth the effort to seek them out in my opinion!

Again, Lesvan there are a lot of choices. Take a look at this review, for what is worth, something affordable and neutral without losing transparency, detail, and dynamic impact. Great "real" soundstage with my tubes and TT.
