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.
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.
