Although most digital protocols do do that, I don't think S/PDIF does? I.e. if there was corrupted dsta, thats what gets played.

Yeah, I forgot that. Was thinking of USB and the like which are bidirectional. As to that thought, never mind.

The test would be to count the corrupted/dropped data packets which may not be readily apparent if the error correction in the DAC can interpolate the lost data.

The USB Audio protocol also does not retransmit on error. There is simply not enough time for that.

Welcome,

No dude - I hear only the voice in my own head. The responses that were given were AI.

I feel sorry for you if you consider what is common knowledge here at ASR as "AI"...

Digital S/PDIF works or doesn't work. Period.

You can also get TOSLINK cables up to 30m, despite the spec limiting them to 10m.

Sure can, but the basic cables are plastic optical fibre, not glass... so those will usually only go up to 5 - 10m for basic or some older ones, 10 - 15m for quality POF cables, but 30m+ for proper TOSLINK optical cables using glass fibre.

is it possible that there is some loss that I am not perceiving, because it is slight - a difference that I might hear if the ability to do a proper A/B test existed?

Think of it like Morse code.

Transmitted over long distance, a message is either fully received, or there were signal dropouts and the received message is obviously wrong/scrambled.

But what cannot happen during the transmission is a subtle change in wording.

It's more about the design of the digital output and input stages than the cable.
Dick Pierce noticed that about 3 decades ago.
Although at over 10 meters, the cable needs to be close to 75 Ohms.

SPDIF is sent within a device usually, transistor to transistor logic. How is the ground developed? , from the chassis?

No, it’s not. From wiki:

S/PDIF (Sony/Philips Digital Interface)[1][2] is a type of digital audio interface used in consumer audio equipment to output audio over relatively short distances. The signal is transmitted over either a coaxial cable using RCA or BNCconnectors, or a fibre-optic cable using TOSLINK connectors.

For transmission on a PCB, usually I2S is used, again from wiki:

Inter-Integrated Circuit Sound (I²S,[a] I2S or IIS) is a serial interface protocol for transmitting two-channel, digital audio as pulse-code modulation (PCM) between integrated circuit(IC) components of an electronic device

I feel sorry for you if you if you didn't see the annoyed sarcasm.

Sorry just saw someone more annoying than annoyed.

Cheers.
