Great Copper Cables?

Please allow me to suggest Audio Note Lexus. They are all copper with a very elaborate topology (same as the AN Sogon, which is all silver and costs several $1000), and they sound great. Best of all they are not that expensive: the ICs are about $175 per meter.

I also love the Nirvana S-L ICs which cost much more, and are a hair warmer.

I found the Atlas Questor to be a terrific budget, quality, high-purity copper interconnect. I use them in my "power" rock/jazz/world music system--Taylo 7U floorstanding two-way speakers, Aragon 8008ST poweramp, Rotel RC 995 preamp, Audio Refinement Complete CDP. Clear, uncolored, very dynamic and speedy. And you can't beat the price--just over $100 for 1m. I get them through my local dealer, Eugene Hi-Fi, whose owners, Chris and Dale, ship internationally. They also sell the entire Atlas line--Navigator All Cu, Titans, etc. But the Questors are great "bang for the buck" cables. www.eugenehifi.com

Encosse Bi-wire speaker cables. Rarely known, priced competitatively, but sound great.
