From what I can see of TWL 7+ pictures, the pairs seems just twisted.
Hi Jazz, If you read some of the reviews of the TWL 7+, they discuss how the 7+ PCs are Litz braided. I surmised they are using WE wire based on the comments about the wire in the reviews (see below) and reading the strand counts of their various products on their website. Their cords also have some other things going on such as deep cryo treatment and something they call "
passive ground plane technology." I have no idea what that is but it could be as simple as a shield connected at one end and spiraling the ground wire outside the shield, or maybe something more innovative.
Below is an excerpt from the PFO review of TWL PCs. Does the description of their wire source remind you of any companies being discussed in this thread?
Peter Grzybowski, President of Triode Wire Labs, found a highly annealed, durable wire that sounded extremely musical and better than anything they had experimented with prior. The wire happened to be designed by a corporation that was dedicated to the propagation of sound quality, at one time employing 10,000 scientists and engineers! This corporation held a tremendous amount of innovations in audio equipment and devices, such as triode tubes, recording, and acoustics, including the patent for Oxygen Free Copper. From further research, the wire used in Triode Wire Labs products was specified for use in the construction of theater amplifiers (including the 300B) as well as recording equipment (Westrex), with ties to Ampex and Altec as well.
