Really good digital should sound like good analog......
But it rarely does.....
It *is* possible to come very close, but it's a lot more difficult than a lot of us realize...... And a lot more difficult than it should be.......
I believe a major part of this issue is just taking RFI, an artifact of digital audio playback, very seriously. This includes isolation at the AC mains (isolation transformers) and at the DAC (optical cables)..... It's amazing how much digital audio improves with these measures being undertaken. (This is also why I always play vinyl with the CD source powered down.)
the day before I got flooded I decided to plug all my digital gear to a power strip plugged in to an isolation tranny that I put together years ago and sat unused. I also had all the preamp gear plugged into a PS Audio IT, so it was plugged into that. I posted about the result already that I only listened briefly the day before I got flooded but was quite surprised at the improvement which was noticeable immediately. And I am quite familiar with changes that are just noticeable blah blah blah on and on.
Analogue like? I don't bother with the usual audiophile terms so just let me say that it was substantial. The only real absolute is the real thing and I have many real things in the house, and play them regularly. I'm a musician, owned a music store, played many instruments, had wonderful talented teachers including one with a Selmer Mark 6, and have advantages that others here only search and dream about. I also find what you're saying has great validity. Cheers
Define "very close."
I actually no longer believe in an "absolute sound" - It doesn't exist. But Everything is relative to something else.
The major problems I see (have seen) for CD playback are vibration, both internal and external, and scattered background laser light, flowed closely by the fluttering of the disc while playing. All of those things are never addressed by manufacturers.
Many people believe the limit is only 5% away or perhaps 10%, whatever. It's the old cost effectiveness argument, why spend another x dollars just to achieve the last 5% in SQ?

"I actually no longer believe in an 'absolute sound' - It doesn't exist. But Everything is relative to something else."
An "absolute sound" is a hypothetical phenomenon..... Even if it does exist, nobody would know what it actually is..... Or how close we are to it......
It's like nothing being "perfect"..... Or not knowing how close to "perfection" we actually are..... But we still strive to get as close to it as possible.....
I do think that if there is an "absolute sound," a requisite to approaching such ideal is to play recordings that enable realization of such standard...... But I do think most recordings would "fail" in this regard...... Even unadulterated recordings in which, for example, may have been recorded in a venue with poor acoustics..... Or a recording in which the A/D conversion had excessive jitter..... (Such recordings would not be helped with the use of "reclocking" at the playback end.) Or a recording in which asynchronous sample-rate conversions had taken place (Beatles "Box Sets" have this issue)..... Or a recording in which "clipping" had taken place or excessive dynamic limiting/compression had been utilized..... Or a recording in which resolution was lost due to improper dither application (excessive noise, dither applied in which downconversion had *not* taken place, etc.)..... (A lot of recordings are degraded in which the chain of custody from recording session to final production disc was "broken" at some point during the process.) A lot of ways a recording can become degraded to where an "absolute sound," if it were to exist, becomes unattainable.

I would tend to agree if there was a lot of "CD quality" playback of music files that improved upon playback of physical CDs...... But I think good CD playback sounds better than good playback of a numerically identical CD-quality file off a server. (The latter is devoid of the issues you alluded to.)
"Many people believe the limit is only 5% away or perhaps 10%, whatever."
It could be 50 percent away..... Nobody really knows......
