All that is wrong with "HiFi"

[SoundMann]

The discussion was about whether CD could always be classed as lossless, not sure why you're suggesting I was talking about dynamic compression?

All digital recordings up to now contain noticeably less resolution than the original performance, and they also sound distinctly different as well.

Redbook CD is a highly lossy format which discards a rather large amount of "least significant bits".

I have argued for years that PCM digital formats are highly flawed. High levels of destructive noise, distort, non-linearities and overall lack of fine resolution have plagued it from the get-go.

High order DSD holds much greater promise, sounding much closer to the original performance. But it too suffers from the same issues, just to a much lesser extent.

was it not about what is wrong with HIFI?

Yes.

The reason I brought it up was because you wrote it in the first place, and then doubled down.

Discussing if CD (you mean actual CDs, the redbook format?) can be considered lossless is a weird question. It is a format with is own resolution and specs. If it is the result of a down sample from a superior format, it is lossy transfer. If it is an original release, it just is what it is. If you are discussing about general capabilities, I like higher resolution formats much better, for a lot of reasons. All formats are limited. But the recording process is the real issue (by very, very far), not the format.
