Bad job Marce, more than 1 page and several 3-syllabic words. His eyes will glaze over before the end of the 1st para. Tsk, tsk 😎

I am sure SY has very acute hearing, no doubt.
"5-6 additional opamp in the chain start to be audible"
So maybe my sonic expectation is too meticulous.

An eye diagram has an opening in the middle, each interface has a certain size this opening can reduce to and still work, if this opening size is not compromised the interface will work correctly....
One thought I did have is that like LPs; CDs are an outdated technology that has been surpassed by holding the data on some form of media storage device, that's what I and many others have done to circumnavigate any perceived problems with CD drives... The only problem with this method as many have said is avoiding hours of scrolling through your music collection and trying to decide what to play... |My way round this now is to put a limited selection of music on a memory stick and use this in my squeezebox.
Wally I use an old Kenwood CD player these days when I do play CD's that I have had for years, I think I got it before my CD63 and Micromega CD player, both of which I sold when I ripped all my CDs.

sadly this is what we are up against Sonore by Simple Design microRendu: An Audiophile Odyssey | AudioStream
The first paragraph is purest FUD.

I wound up with the index on html pages, so can be viewed / controlled from any device, and the index is small images of the covers. I find selecting by cover image much easier / more satisfying! It's not unlike the old way of rifling through album covers...
It would be simple to show the noise with and without this gadget. I wonder why they didn't?
Or maybe I don't wonder.

I just love those audiophile ethernet cables... Fascinating how little about data transfer and networks these "experts" actually understand...
I lose a lot of interest without a physical copy that I have to change . In fact I don't think of be an audiophile without them.

I see we are talking that bit transfer is not the matter here and we agree on that part. Also I set jitter aside ,do I miss something ? seems we are talking same thing here.

let me clarify the second part of my sentence after the coma : for example CM noise radiated/returned from transport via SPDIF cable, in this case as usual connected to a DAC.
Am I missing something else ?

This is a simplification of how complicated it is to just attempt 99.5% bit perfect, and you don't always get that even on brand new discs. Streaming, even with buffering, isn't like reading data. Reading data can infinitely buffer. That's probably why installing from CD's takes longer than USB or such.

Stunning how this folklore persists, even DOS has UNIX like bit by bit comparison utilities. I copy a software install CD at 8x and surprise the software installs and runs perfectly on another computer.
And you can do a checksum and it will agree. Amazing. 
Don't believe it? Testing it yourself isn't difficult. It's worthwhile to test it, if you worry about these things.

Can any of you that have argued the point please give some proof that distributable software is relying on bit perfect copies? Again, my background tells me that can be worked around. For Pete's sake, aren't any of you guys old enough to remember Usenet? You could be missing a significant portion of a file and the elaborate checksum systems would recreate the corrupted/missing portion. So stop gang-regurgitating the same point, and cite some proof.
Why don't you just try it yourself and see? It's not that difficult.
FWIW, I partly agree with you, I don't think that a few bits out of place will keep a piece of software from functioning. That seems like myth, too.

Well, here's a quick one: downloadable software typically publish the md5 quicksum of a file/batch. If that doesn't match then the data doesn't either.
Again, I'm 99% sure we're talking after error correction/parity and resends have been dealt with here (if we must stay in the realm of IT).
Here's the proof: stuff works.
What's your point the result is bit perfect BECAUSE of the embedded error correction, CD's have and need it. You please prove that playing a CD on a decent player results in uncorrected errors and interpolations at more than an infinitesimal level.
I have trouble attributing a "sound" to one or two bad samples on a whole CD, the claims only make sense if there is a continuous stream of uncorrected errors to the point of sillyness.
