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?

Sounds like in this case streaming is for background music and vinyl and cd (also questionable) for serious listening.

overall stubbornness reappears and shuts the gateway of brain.

I thought it shouldn't matter but it did. The $249 is better than the $14 one. I think that has to do with shielding and other types of interference than jitter.

In response, I would say that my ear has caused me to buy very wisely. I can hear things that people at audio stores can't. I don't know why or how, but I have developed a very good ear and I think that beats science any day. What's the point of science if not to point you to good sounding gear?

I happen to be writing about this now and it's a much bigger topic than you might think. At the turn of the 20th century scientists thought they had it all sussed. At the turn of the 21st century scientists are willing to admit that there is more they don't know than they do know. I'd say trust your ear over anything else when it comes to audio.

You're kind of half right. When I write I have to do a lot of thinking about things that come from both my conscious and unconscious. So I often stop,  waiting for something from my unconscious. Then music lubricates the gears or fires up the synapses or however you want to think about it. Also, if I am listening to something i know well, then I don't need to give it my full attention.

In the afternoon when my brain is too tired to write, I often explore new music. Tomorrow when my wife will be gone, I will stream Robyn's new album very loud to feel my three woofers shaking the room. But I've also been exploring recordings of the violinist Patricia Kopatchinskaja and the pianist Fazil Say. I found a recording of them playing together. New recordings are almost all digital so I'll never hear them from an analogue source and my Moon 280D reproduces them quite well.

@audio-b-dog got it. I’m half right. You write when you’re unconscious. MQA is DSD and you have 3 woofers in a stereo setup. 
I’m gonna go have some coffee to stay conscious. Enjoy your weekend!
