Glass v.s. Plastic Toslink

only applies to digital coax, not optical cable.

To me, plastic sounds the best. I have tried many times multi-strands glass, and and the plastic always comes right back in my system because it sounds more coeherent, more balanced without edgy trebles.
Keep in mind that Toslink connections were conceived with a plastic monofilament of a certain aperture.
Glass never matches perfectly the correct aperture and the light gets bounced and reflected throughout the multi-strands for more jitter.
multi-strands glass in not used in medical equipment because the light in not precisely conducted..

Another vote for Silflex glass optical cables.

Hi chrisr,
Your conclusions are opposite most everything I've read. Glass optical cables came from the medical field. The company I chose, Silfatec, does mainly medical.
I have tried a few plastic, even one more expensive from Chord, and they seemed great for the money, but these glass ones bettered all of them, at my house, with my listening panel. Not the least bit edgy, or sheeny as some of the plastic ones.
Everybody's different :)

Yes - I know... glass I have tried were the sonicwave and another one... ihave got to try the silflex then someday.
