Recommend toslink cable for 24/192

[Aldoszx]

As the title says, I need a toslink cable to care 24/192 from my PC to the Topping D50s DAC.
I have a couple of toslink cables, but none of them can be usable.
All of them are good for 24/96 but not for 24/192.
Do you have experience with some toslink cables I can use?
Thank you !

How did you figure out that your current cables will not carry 24-bit/192k audio?

 

[Aldoszx]

@twsecrest, I have just tried them !
One of my cables gives no sound with 24/192 signal.
The others, have a lot of gaps, pops and cracks when playing 24/192.
If I set max rezolution at 24/96, all of them can handle it.

For Toslink cables, I usually use buy whatever Monoprice has.

If you connect using USB, does it work better?

Toslink is capable of 92kHz 24 bit: https://thewelltemperedcomputer.com/KB/Toslink.htm
That article has a broken link to glass toslink cables. Most are plastic.
The company appears to be still alive: http://www.lifatec.com/products.html
The article does say modern hardware may outperform the spec. Probably not to 192kHz though.

OP, are you sure it's the cable and not the chip sending the signal? Very few Toslink outputs will work at 192/24. This includes most of the popular Realtek chips found on motherboards.

USB is usually better, why use S/PDIF toslink optical?

If you’re in Europe, the KableDirekt toslink cables work all the way to 24/192. I’ve used about half a dozen of them up to and including a 5m version. All have worked flawlessly. They’re cheap to, available on Amazon.

USB is usually better, why use S/PDIF toslink optical?

Avoiding ground-related noise issues when using single ended interconnects is one common reason.

 

[wwenze]

Avoiding stuttering is another. When recording with my Elgato I have to switch back to Intel HDA instead of using my USB DAC.

It's the TOSLINK receiver that is the limiting factor.
Not the cable nor the transmitter.
These all can go much higher.
Some receivers can actually do 24/192 but it is right at its edge of performance.

 

[Jimbob54]

An amazon basics toslink cable will happily do 24/192. The sending or receiving device may not.

Edit @solderdude beat me to it

I am a Roon user, with Raspberry Pi endpoints.
So, my D50s is connected via USB to RPi.
I have to use PCs optical connection for Amazon Music.

Hm, I am gonna try to connect same cable to another DAC. Maybe this is the problem.
Maybe JohnYang could tell us if D50s support 24/192 via Toslink.

ALL of my motherboards work fine at 24/192 with these cables, and ALL of the use Realtec chips

Thanks, but I coul not find Monoprice products here.
I am in Europe.

Toslink cables are NOT the limiters.

TOSLINK receivers are designed up to 5Mbs some up to 8Mbs.
It is a technical limit because these receivers are intended for Asynchronous transmission.
There are also newer receivers that can reach 16Mbs (Asynchronous) with receivers all the way up to 155Mbs (synchronous)

44.1kHz/16-bit: 44,100 x 16 x2 = 1,411,200 (1.4Mbps)
96kHz/24bit: 96,000 X 24 X 2 = 5,308,000 bits per second (5.3Mbps)
192kHz/24bit: 192,000 X 24 X 2 = 9,216,000 bits per second (9.2Mbps)

 

[Aldoszx]

I understood.
On Topping site it states for D50s that could handle 24/192 on digital input (SPDIF and optical).
And, like I said before, one of my cables could not handle at all 24/192 (no sound) and others plays but with interruptions.
That's why I think the cable is the problem.

 

[Bullwinkle J Moose]

If your operating system cannot handle 24/192, then the receiver is irrelevant

Some operating systems create gaps, pops and cracks even at 88.2, such as Windows 8.1 (with certain hardware options) or NO option for 88.2 with other hardware, yet Windows 10 and even Windows XP handle 192 just fine

It is not just the cable, not just the receiver and not just the O.S. that you need to look at

It is the combination!

I have latest version of W10, and Realtek ALC1150 audio codec on the motherboard.
