The way I [and many thousands / millions ?] of other quality audio enthusiast look at it...

As long as the original recording / digital safety copy is preserved and stored for posterity,
we can bugger about as much as we like with editing software, tonal manipulation, special FX, or whatever...

That's all part of the fun of enjoying music and sound...

Remasters, remixes and mashups have become a significant part of modern music culture....

Anybody with a computer or even smartphone can access software to denoise - or add noise - to any track..

Nothing is absolutely sacrosanct..

But just as long as the original remains securely undiluted, unabused, and accessable in safe storage..
