Cables for high efficiency speakers?

Thanks all!

It is my intention to try what I have, as I've had them for fifteen years. I won't be on a never-ending quest. I'm asking the Forum, in order to avoid the hype of manufacturers and discover any recommendations from people with real experiences.

If I'm fortunate and see a pattern in the responses, I may choose and borrow a cable product to compare. Right now, I have nothing to compare or even a starting point. For me, this is a main reason to join a Forum.

Zu audio or Kimber Cable works great with high efficiency speakers. Cable with high efficiency speakers is not too much of an issue. I would not use a thick guage wire because a high efficiency speaker will react adversely to with skin effect. My friend uses Zu cables on both of his high efficiency systems. Ons system has a pair of highly modified Klipsch heresys and the other has a set of Zu Superflys. Both systems are killer and the Zu speaker wire made a noticeable difference in both systems.

OCOS and Supra Ply 3/4 are two that I would recommend. I use a 5.5m run with both 92db and 95 db speakers that have a smooth impedance curve. These cables work fine and won't break the bank.

I use Coincident TRS extremes in my system. This company specializes in high efficency speakers, amps, and cables. They are reasonably priced

Thank you for the recommendations. Stan makes a good point about silver. For example, the Horning speakers I'm considering are internally wired with copper. However, the Stealth cables that are usually recommended for them are silver. What's up with that?
