Does High End In Wall Speaker Wire Exist?


So I'm in the process of reconfiguring my system after a recent move. My plan is to run a 25' pair of speaker wires through the 1st floor joists from my Sophia 3s to an equipment cabinet across the room. I'm trying to achieve a very clean and uncluttered look and avoid having anything between the speakers. With that in mind, I'd like to use in wall speaker wires that will do the Sophia3s justice. Any recommendations? Less than $7k please.

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.
