Doug, I've used Kapton for several years on my tape driven turntable. I've tried several different lengths and thicknesses. It is too smooth so it doesn't grip as well as stock Mylar. I don't know where you could obtain this material since I don't believe the company I worked with would sell to the public. I run a machine shop so it's pretty much standard business practice. It's also extremely expensive.
Teres Versus with Galibier/Redpoint?
I'm planning to add another turntable to my system(currently have VPI SSM rim drive/10.5i). Along with the Raven AC, I'm most intrigued by the Galibier Stelvio and Redpoint Model D. Any of these tables would allow the flexibility of Differing/multiple arms and a contrast to the sound of the VPI. One potential advantage to the Galibier and Redpoint might be the ability to position the Teres Versus next to the platter as an alternate drive method. In this way, one might be able to use direct drive and tape drive interchangably. Does anyone have experience trying this or is the tape drive good enough that this would make little difference?
