Toslink/optical cable recommendations

xti16, you're welcome.  Cutting ground loops is great but Toslink sometimes is worse than coax.  It is a system thing.  What works for somebody might not work for you.  Optical drivers have slow slew rate (transition time) making transition recognition moment susceptible to internal system noise (producing jitter), but at the same time Toslink is free from transmission line effects, from electromagnetic or capacitive coupling of electrical noise and from ground loops.  Clean power supply (conditioner) could be beneficial  with Toslink.

Mitsubishi eska pof.

meets toslink wavelength and aperture requirements, 0 tolerance.
No fractured glass fiber for 0 induced jitter.

I have both the Unique Products glass toslink and the Wireworld (I think I have the 6) and have done comparisons. While the U.P is an incredible value and produces excellent sound, the Wireworld is superior in terms of sound, materials and construction. The improvement is sound is quite discernible on fine high end equipment but maybe not very discernible on routine equipment.

dne, is the Wireworld cable glass or synthetic fiber?  Just curious.

The Wireworld is glass.
