Just want to say that these are great. As much as some people may say I'm full of it, I have actually noticed a difference between optical cables, particularly one on Amazon which accentuated treble a bit. I went in expecting cables to make zero difference, but my experience over the years has proven that wrong.

i've both wireworld supernova 5+ cable and the lifatec Glass toslink cable.
Lifatec is superior.Especially on high frequencies where their reproduction is more clear and natural.
The cymbals or the hi-hat of the drums on well recorded songs sound real.

So if you want to get the best optical glass toslink cable get the Lifatec!

I used a number of other optical cables until I recently gave the Lifatec another try with my newly acquired Gustard U18. I think Lifatec sounds much better than the others I have tried with my ROHM chip SMSL D300. .
