Optical cables

[cyclopse]

I have never heard an optical cable that sounds different from another one, tried the Fiscal and it sounded no different from a more expensive Chord Optichord I have.
I tried the Fiscal on my Sonos Connect for a week and it killed the sound, flat, lifeless, boring. Changing back to coax with a 20yr old DPA cable restored the sound to something more acceptable.
Maybe glass optical cables sound better?

I had similar results with a toslink digital connection. Settled for AES/EBU for a much better presentation.

Best digital connection I've heard is a transformer coupled 75 Ohm BNC to 75 Ohm BNC.
By quite a large bit actually.

Did the glass optical thing, even the high end USB thing and I keep coming back to this.
Decided to trust my gut, got the best cable I could afford and have never looked back.
