@audio-b-dog . I never realized that jitter had "a sound" Did you measure the jitter? What was the jitter before you changed cables? After you changed cables?
Thanks,
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?

@grunge1000 Sorry, I can't measure jitter. Maybe it was some other sort of interference with the signal. I'm not a measurement guy. I use my ears. The difference between the 50 ohm analogue interconnect and the 75 ohm Purist Audio Design Genesis Luminist was hard to miss. I don't think you'd need to be an audiophile to hear it. In the reviews I read of the Purist cable, I bought something called the "entrance to the high-end." It was mentioned that the cable I bought errs on the "musical" end of the spectrum. More expensive cables would have a tighter sound and be more "analytical." Anyway, for my test, I'll just have to trust my ears, which is what I always do. This cable will be rarely used when I use my transport to play a CD. I rarely do that. |
Thanks @audio-b-dog |
Why would you use anything but usb if you want the higher sample rates and dsd which sounds better than cd 16/44? Toslink usually has weaker specs than coax and coax has weaker specs than usb and usb is terrible. Ethernet and i2s are better sounding than using usb. The data going into my dac from my streamer is in the form of dsd256 and the better i2s cables make a difference. |
Good question. I use the ethernet port on the Moon 280D streamer to connect it to WIFI. My old CD player (transport) does not have a USB port. So, I can connect the CD transport with an optical port, which I had done, or with a coax port, which I'm now doing. All the information I've heard or read says that coax is better than optical. And that's what I've heard with my own ears. But the Moon 280D's USB port must unfortunately remain unused. Unless I connect the TV to it, which I think I will do. So, now tell me anyone, how expensive a USB cable should I use? |
