I take this question in a different way, ErinDillyFan, than you'd probably assume, for two reasons.
One, I'm an audiophile. I find many older recordings, great though the orchestrations and performances and historical value may be, unlistenable to my ears because of the dated production and engineering of the recordings. Which is a shame. But I often listen almost exclusively to revival recordings of classic shows because my ears can better appreciate the crisp, modern (and yes, often pared-down sadly) recordings in a much better aesthetic atmosphere.
Two, I absolutely 100% prefer acting over singing when it comes to musical theatre. Give me a broken note, a pained wail, a 'character' voice to sell a joke over a plainly-sung gorgeous tone and technique every day of the year. I love a good melody. I love a good story more.
Words don't deserve that kind of malarkey. They're innocent, neutral, precise, standing for this, describing that, meaning the other, so if you look after them you can build bridges across incomprehension and chaos. But when they get their corners knocked off, they're no good anymore…I don't think writers are sacred, but words are. They deserve respect. If you get the right ones in the right order, you can nudge the world a little.
