Analog compared with Digital

PRaT is definitely the difference between not ideal digital and good analog for me. I used to think PRaT was group delusion like stuff.

At an open house for a local audio shop years ago, a guest brought a couple of CDs. She played one as background music and things kept going on as if nothing changed. She played the other and all conversation stopped as people listened. They were bit identical but she had used an option that “lowers the jitter” when burning the 2nd CD. I have no idea what that option actually did, but it very clearly worked.

I do think that jitter is often a culprit with digital, but also HF noise from the digital affecting the rest of analog systems is often a big problem too.
