glass toslink does work

Agreed. I also tried a glass Toslink awhile back and was really surprised at the improvement. And it wasn't an expensive one, though I'd don't recall offhand the website where I bought it.

Even if you have a brand name Toslink, unless it specifically says it glass, it's almost certainly plastic.

Optical grease? Do tell Elizabeth...

Try the wireworld glass toslink. I put one between a client's Mac mini and his DCS dac. It is killer good

i second thesoundhouse's opinion. i do the same with a wyred 4 sound dac2.

I recently switched to glass (Silflex $60) and made a big difference vs. the $20 'good' quality plastic.

Elizabeth, where do you find this stuff??!!
