Thiel Owners

@tomthiel Alpha-Core on some of their products lays down ribbons of copper and/or silver flat, then puts flat thin ribbons of polyester terephthalate between other flat layers ribbons of copper and/or silver on top of those layers, then twists the assembly and then encases the twisted assembly in a thick wrapping of polyester terephthalate. This keeps one side of the ribbons in constant contact rather than rotated intermittent contact as happens in braiding. Though this purled (twisted) process should have some advantages, many believe that the non-twisted completely flat versions sound better. It has been suggested that this might be due to the thinner outer casing of the flat series. The twisted "purled" versions are said to be much more durable though. I believe Thiel Audio used the "purled" versions for the added durability. The beefier flat MI 2 & 3 and AG 2 & 3 speaker cable versions are separated by Teflon rather than polyester terephthalate.

Wireworld claims their ribbons lay flat but the images suggests this might only be partly the case.

...And foamed teflon had been introduced sometime ago.

Anyone who watched the cable video from Galen Garies..
Does Galen ever mention what happens to the signal in wire when it’s beaten up under the constant pounding and pressure inside a speaker box? The Sonoran Plateau wire I use in my cabinets is the only wire I have seen in a box that makes an attempt to cancel or reduce vibration that attacks the wire while under duress. I would love to hear Galen’s take on signal transfer in such an environment and how it may alter the electro magnetic wave thru the wire. Tom

Tom - can you tell us more about your Sonoran Plateau wire?
For the record, in his final products, Jim threaded the driver lead wires through silicon tubes suspended between the braces. Can anyone tell me if those tubes are affixed to the cabinet walls, or are they stretched in space? My proposed wire augments Jim's 18-2 solid in hard teflon twisted pair with an additional pair of 18-2 stranded in foamed teflon. The 4-wire bundle adds both mechanical and electrical damping for a cleaner signal at the driver. I'm still invistigating flat wire and other ideas. Again Tom, can you talk about Sonoran?

And thinking about what Galen has designed...
Maybe he could take what he has derived from his studies and apply the 
appropriate set of rules to the winding of audio inductors and transformers. I need some new inductors for my new speaker layout and watching his video has helped in the aide of my selection for the two values needed. Tom

The conductor and all its surrounding and wrappings are placed in a clear tube which is then filled with micro bearing steel and sealed at each end except for the required length for proper termination to a terminal lug. The size of the bearing matters because you can over damp the cable if it is run externally ..I know I can hear that..but taking the speaker apart several times to listen and compare bearing size over again that is a real drag but I bet their is a difference there also. I learned much from the video and now I wish I could go back in time because he raised a whole lot of ??s in my brain.
