what is the best speaker cable?

Cardas Golden Cross or Golden Reference is my favorite.

Vinnie:

Keep in mind as you are searching for speaker cables that there is NO one best speaker cable. It depends on your system, your musical tastes and how you want your music to sound.

Happy listening,

P.S. However, I have found that the Discovery Signature cables are quite good. . .nicely balanced and not sterile or amusical.

While recommendations from others are a good starting point, shopping by brand or price can result in a big waste of money. I would always try before you buy. The best source I have found for this is The Cable Company (1-800-FAT-WYRE). They rent cables (Speaker/interconnects)for about 10% of the purchase price and all rental fees going towards any purchase you make from them (they also have equipment and accessories). They carry essentially every brand of cable available, so you can try a wide range of brands and prices. Even the outrageously priced exotics (like Nordost Valhallas)! You may find that a brand you hadn't even considered may be best (as I did when buying inexpensive interconnects for a friend. The Wireworlds I tried were far better than anything else in the price range!).

Hope you don't mind my asking, but I also own the Prima, and wonder what the change to the Telefunken tubes gave you in terms of sound quality? Also, where did you buy them?

I know that almost all brands of Monster are the worst.
I use a short 3'runs of isolated speaker wire from VanDenHul(CV-122H model if I will trust my memory). Before I've plugged them instead of my JPS Superconductor cables, I plugged them into AC outlet with 200W bulb for about 2 hours for real break-in. The result is -- I've sold my JPS cables after I've pluged in these magic wires. I've paid just $60 to get this wire, and I use silver-solder covered bare wires to connect to binding posts.

Among brand names there are only few brands to pay attention for VanDenHul, AudioQuest and Cardas(newtral reference).
