With the acknowledged failings of current compressed software, what I am suggesting is that some equipment does a subjectively better job of representing the live experience than the simple zero distortion chain.
If there are any failings in the recorded software, then it is an artistic choice. The recording chain is not at fault. Redbook CD is a better technology than any analog master tape (and analog is what you mentioned earlier) that you are likely to encounter - the very best analog tape has 75dB SNR, and CD can do 20dB better than that.
Now, before you mention SACD or DVD-A, let's put some perspective on those formats: DSD came into being because sony wanted to build
cheaper dac's. DVD-A is arguably a better technology (eg. "perfectable" dither). What both formats have going for them is multi-channel which is a step toward a more realistic rendering of the sound of a live event (providing that it is used sensibly and not for putting the lead vocal behind the listener

)
FWIW, I am not advocating heavily distorted loudspeakers. The subject was amplification and source components. We are talking about some equipment whose aestetics leave a great deal to be desired even compared with the Rotels and Yamahas of this world. We can include Michael's home made Dac in a perspex box (c.£100). We can include numerous Chinese made valve amplifiers below £1,000.
But there's little to be gained by adopting 2nd harmonic distortion as a step toward a live event. It's simply the wrong kind of distortion (see below).
The simple question is this. Are those who build a system around measured accuracy any cleverer than those who use live music as a reference?
It is possible to make an accurate system inaccuate, but not vice versa. For instance, I can get a (pair of) guitar effects peddles for example, and use them to generate as much, or as little 2nd harmonic as I like and I don't have to hardwire that sound into my amp. It's not hard to simulate various kinds of distortion digitally, and more importantly as a switchable and
extremely cheap option.
To suggest those in the latter camp are deaf is somewhat insulting, particularly given that they are generally highly experienced music listeners.
If you prefer a system with distortion, then that is your choice. If you were fail to detect the distortion for what it is, then you are deaf.
BTW: Your "highly experienced music listeners" have no better innate hearing ability than everyone else.
In closing, have you ever heard a commercial CD played back through a studio setup? I presume you have - I know I have. can you honestly say that the results get anywhere near experiencing the live session or even the original mastertape? No of course you can't. Once you have heard this demonstration, the idea of subjectively improving on that state of affairs becomes not just attractive, but critical to true musical appreciation IMO.
I'm confused about what you're advocating then. Are you saying that the recording studio should pre-distort the recording to suit your quest, so that you don't need to?
Or, are you advocating greater accuracy in the recording process so that you can take the original and distort it at home to meet your needs?
You seem to want the second of those two options, otherwise you might still not like the results of option 1, where the interpretation of "live" is stamped on the recording during production.
Now, let's turn to the type of distortion your adding. Why are you going down the valves and vinyl road? [It appears to be a fashion thing?

A major factor that distinguishes a "live" event is the room reverberation of the auditorium. This is nothing like 2nd harmonic in structure, so valves will get you nowhere. Why not get a reverb unit or, better yet, why don't you try some of the ambience creation modes in a surround sound processor instead? [Oh wait, no kudos there

]
Seriously, Logic7 from lexicon/Harman Kardon can do a lot of what your asking for with a 7.1 surround sound setup..
