Is upgrading worth it?

I expect the music of an era gets recorded with an eye towards the equipment of an era, which might account for the "vintage effect" described in the OP. I remember being shocked at how "right" Dylan's "Desire" sounded on some old speakers from the 70s, with their huge sloppy woofers.

That said, music played audiophile gear needn't sound like edgy etchings from hell, though it certainly can.

If you're continually upgrading and become less satisfied with the result you need to be "A" doing more research and"B"auditioning,providing of course you are residing in an urban environment.

you could not be MORE CORRECT regarding a LOT of music from past recordings/groups, ESPECIALLY rock albums, but many others as well. some time ago (1970's) i had a Fisher receiver, Fisher speakers, and a Garrard turntable.
the entire system set me back $350 (all the wire was included).
whether it was Gentle Giant, The Who, Simon and Garfunkel, etc. EVERYTHING sounded great. later i upgraded to a Thorens which was a far more elegant machine, but truthfully the Garrard worked fine even with all of the cheap plastic parts.
everything was fine even a couple of changes more down the road, UNTIL-
My "GREAT DOWNFALL" - THIS began with the purchase of B&W 801 speakers. now my classic-rock collection started to sound like the music was pieced together with spit and glue- tonal variations, pauses and timing errors in the mixing process, too much of this and too little of that, etc. started to make me gravitate to classical recordings, blue-note jazz, acoustic folk groups, female vocals, etc. Cream and C,S,N &Y didn't sound so good anymore. my beloved J.Taylor alblum (S.B. James) sounded constricted and artificial.
Anyway, I feel there is a good reason to advance to a certain level of Speaker Resolution and then hold off- AT LEAST until you understand what is certainly going to happen to your ability to relax and enjoy "those recordings i have alluded to". when you get a pair of super-speakers with kevlar, carbon fiber, beryllium, diamonds, and dense HEAVY cabinets, ELLA will send you into rapture, the NY Philharmonic will invite you INTO Lincoln Center for a concert,
T.Monk will save you a seat in a downtown club. but don't expect a sloppy production to sound good as well.

A few thoughts:

Highly produced classic rock of the 70's was engineered to sound GOOD/FUN/PLEASURABLE -- not LIVE -- through the typical home stereo system. The audiophile obsession of the '80's and later was about replicating a live acoustic experience. So, much of the gear ended up sounding etched and analytical in the quest for acoustic detail. This had the effect of snuffing the life out of the musical experience. It was depressing. Of course, the advent of digital and all of the accompanying sins of its youth, did not help matters.

I made a decision about 15 years ago that in all future upgrades, I would forego detail and resolution in the interest of tonal balance, PRaT and general musicality. This decision highly enhanced the simple enjoyment of sitting down and listening to tunes. Every subsequent upgrade has yielded greater detail, more resolution and transparency, but NOT at the expense of tonal balance and musicality.

Interestingly, I now have a system that allows me to listen and ENJOY all the old stuff from my teenage and college years. Classic rock sounds great, but so do symphonies and small jazz ensembles.

Bravo Turboglo.... my thoughts exactly.
