I heard a sound difference between different optical cables! 

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.

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

Thank you for being brave and making this video even that everybody's going to say we are cuckoo for Cocoa Puffs

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. The only way in which these cables will really differ is in build quality, so I definitely wouldn't waste any money on super expensive optical cables.

Excellent, subscribed.

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.

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

wow, for the first time I see such a short pinkie

the mental gymnastics never ends 😅

Phillips cables sounds ok Monster cables THX certified sounds bassy but lacks details Pearl AQ sounds crispy, clean and the dialogues perfect and very detailed, even some 3d details but lacks some bass. Thats all folks!

If you understand fibre optic transmission you know this is nonsense. I worked in telecommunications with fibre, fibre is impervious to any issues related to copper cables. The only issue would be if damaged or connection is poor either end. It either works or does not work. Considering the ridiculously short fibre for a interconnect issues such as vibration are again nonsense.

It's about light my brother, and the dac. The digital to analog conversion is not produced by a cable. External diameter is only coating that offers you some extra strenght, to not ruin with 90 degrees path.

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

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

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

My boss system came with the cable you call cheap worked fine

Uh oh,here we go....

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

$400 and you said its natural , good sound stage , detail and whatever, Its garbage bro, imho You need at least a $20000 cable to translate the file into and acurate signal

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

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.
