I agree, but with one caveat.

Fully analog tube amps do definitely produce a warmer/richer sound with less complicated things to go wrong. Artists like them because they are reliable, generally user serviceable, (usually just need to replace bad/old tubes) and makes each recording sound relatively unique.

The thing is, is that it really only works during production. Unless being cut direct to a master record, the sound will get saved in a digital format to produce the user-facing media, which can include digital-source vinyls.

Those products marketed to audiophiles try to take the digitally recorded/archived products to "try" making it sound like the original.
