Does High End In Wall Speaker Wire Exist?

If you install a conduit such as Fiber Optic Innerduct in your walls you can run whatever you want point to point as long as you install a large size say 1" or larger. Keep your bends smooth and gradule and you can install or change wire in the future if you wish. If fire codes become a concern you can use PLENUM rated duct allowing any type wire in the duct to pass fire code.

Interesting - so run a conduit that passes fire code and then thread the speaker wires through the conduit. I think I'll look into that - thanks.

Transparent sells lengths of in-wall cable.

Analsys Plus and JPS Labs makes speaker wires for just that application.

I vote Transparent Cable, great match for Wilson speakers. You run lengths of their in wall cable and then it terminates at a wall plate. From there you connect short lengths of speaker cables with the network boxes on that cable to the wall plate and hook it up to your speakers. It's a great upgrade path too. Buy the best cable you can afford for the in wall portion and then upgrade the network boxed portion as funds allow. They have different levels of "tails" just like their normal cable line. Start with Super now and upgrade to Reference later.
