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?

chatgbt on "New Moon Daughter"

1. The Original Recording (1994–95)

Cassandra Wilson recorded the album for Blue Note in the mid-90s.
Despite the era, it was tracked and mixed to analog tape. Craig Street’s production style leaned warm, spacious, and organic — not early-digital bright.

That woody, shadowy atmosphere you hear? That’s tape.

2. The Pure Pleasure Reissue

Pure Pleasure is known for:

  • Licensing original master tapes

  • Cutting in the UK

  • Avoiding digital steps when possible

For New Moon Daughter, the label indicates mastering from the original analog tapes, making it an AAA chain (analog master → analog cutting → vinyl).

They don’t usually hedge language. If digital were involved, it would be noted.

We did start with a digital cable, but I've started several forums that end abruptly. As long as people are still interested, why not keep going? My feeling is that these forums are for audiophiles to talk to each other. If I'm wrong, I could figure out what we're talking about and start a new thread.

I know what you mean.  I started one about cartridges that is now on its seventh page ... it is hard to know when a new thread would work and be worthwhile

my Meitner DAC upsamples everything to DSD1024 

Which is the right way to go, in my opinion.

The ESS dacs in the Bluesound can natively handle DSD1024 but the unit is restricted to DSD 256.  This is consistent with converting DSD to PCM at 192-kHz and feeding that to the dacs.  Cannot find where I read that they do this ...

With chip DACs your working within the limitations of the chip. There’s a reason why ESS based Bluesound is limited to DSD256. 

I am not a fan of ESS based DACs in general. The sound of these DACs in my experience is direct and leans clinical and analytical. There are exceptions and the final result depends on implementation and analog stage.
Soulnote DAC is ESS based. I heard it at a show and it was very good sounding. Yes super detailed and open sound but managed to not veer into the matter of fact, analytical presentation too much. At the end of the day ESS based Soulnote and Bluesound are completely different animals. Simaudio Moon is ESS based as well if I’m not mistaken. Matter of preference. I wouldn’t trade my Meitner for an ESS DAC.
