Total placebo effects it's impossible to heard in audio differrence with any Toshlink cables

I suspect any difference you think you might have heard is actually just a placebo effect. Unless a cable is faulty, there shouldn't be any difference in sound between those optical cables. That's because the signal is transferred digitally, not analog. The conversion from sound (digital) to light and back also happens outside of the cable. If you would do a null test, you'd see that there is actually no difference in the received audio from the different cables.

I've experienced this too! Cables 100% change the sound. I prefer mid range over the most expensive.

Phillips cables sounds ok

Some years ago i purchased a qed carbon optical toslink, it made the audio worse compared to my regular existing optical cable, i sent the qed back. I was amazed there would be any different. Since that time i have also discovered coax digital cables can also sound different.

thanks for an interesting and rare review of optical cables, very little information, very good result AudioQuest Diamond glass but it's expensive, спасибо 🙏

placebo only,... you just cant.. its the same data signal... and light dont distort.. (maybe on a damaged fiber you can get some clipping)

Uh oh,here we go....

Nice review! My comparison between QED Quartz Reference and AQ Vodka is slightly different. Vodka indeed sounds more natural and stage is bigger but QED has more details and therefore makes listening experience in a way more interesting compared to Vodka. Also in my setup Vodka is darker cable. So which in better...hard to say. I like them both.

The only way to know if there is any difference is to measure the output and compare. With optical there should be no difference at all if you overlay the waveforms. I

It's about light my brother, and the dac.

Amplifier with Optical output to CD player with optical input = better sounding than RCA TO RCA connection?

Optical cables add nasty jitter and degrade music. A horrible interconnect. Use coax

$400 and you said its natural , good sound stage , detail and whatever,

Only a nutcase would pay those crazy prices for the so called high end cables, any well made optical cable around £7 to £15 is all you need.
