Do I need an expensive digital cable?

I have been using a fairly inexpensive optical cable to connect my CD transport to my Moon 280D streamer. I was told that an SPDIFcoax cable would sound better. For an experiment I purchased an inexpensive Pangea coax cable. It didn't sound at all because its terminator ends did not fit snugly in my equipment. I consulted chatgbt who often gives me audio advice. It advised that for the short run of 1 meter, an RCA interconnect would work. It did. And sounded much better than the optical. Chatgbt said that RCA interconnect was good enough.

Now, there is a twist to this story that might make those doubters think twice. A digital cable carries packets of information that are rechecked to assure that the streamer is recieving correct information. There is the timing concern, though. But my Moon 280D has an asynchronous DAC with a clock as part of the DAC. Any information sent by my transport, whether it is clocked by the transport or not, will go through the Moon's asynchronous DAC's clock. So ;there shouldn't be a timing problem. Should there?

Can anyone make a case that I should buy a "better" coax cable?

BTW, I have tested cables before and can hear the differeence, although it can take very serious listening and a long time. Perhaps days. But I can hear the difference.

The thing about cable is will I hear the difference when I leave the room for a while and come back? Will I know if I'm listening to a mid-tier or high-tier? Focusing on differences is very different than listening to your stereo for pleasure. I am fairly sure that if I went from my mid-tier cable to Nordost's most expensive cable that I would probably know, after leaving my listening room for an hour or a night, that the uber-expensive cable was in the system. But it would probably be $20,000 plus, and for that I could buy a really good streamer.

+1 on Soix regarding even a modestly upgraded cable.  I upgraded from  generic cable to connect my CD player (used as a transport) to my DAC to a DHLabs RCA coax, and the resulting improvement was quite noticeable.  Cost was $230 but they offer a 10% discount to first time purchasers at their website.  Both the USB and Ethernet cable connecting my streamer also are DH Labs.

Get this audioquest cinnamon digital coax, it’s around a 100 bucks, all you ever needed. 99.5% of guys can’t reliably tell sht past that in 99.5% of rigs when the blindfold comes on....

Send the $14 one back. 

I think the above information from Simaudio suggests that the quality of the cable running from the CD transport should not matter at all. My $14 one (on the way) should work as well as a $4,000 one. Anyway, I will test it against the RCA analogue interconnect that does seem to work quite well.

I can recommend the fairly priced SPDIF cable from Cullen Cable. I’ve been using it for a few years from streamer to Pontus DAC and am very pleased.

I am sure all the cables you are mentioning are excellent, including the DH Labs, which I looked at, but for 1 meter it was $280 plus tax, etc. Over my budget, especially since I do not know what will happen with this asynchronous DAC.
