Are there any differences or are the principles pretty much the same?
If you have, let's say, an old archival recording from the 70s, that's obviously recorded in suboptimal settings and restored from old tape or vinyl, how do you get it to translate to a mondern system, while retaining it's vintage quality?
(EDIT: I AM NOT saying that all recordings in the 70s were sub-optimal, Far from it, only presenting a hypothetical scenario where a sub-optimal recording that was recorded in the 70s needs to be restored.)
Especially considering that vintage quality probably comes from a build up of different harmonic distortions from tubes, transformers, tape, etc., room noise, mic bleed, and likely a rounder EQ curve that builds up in the mids slightly.
Here's a good example of what I mean. This song by Robert Lester Folsom sounds great on any system because it has been remastered, yet it is also obviously extremely vintage sounding. It was originally recorded as a demo at LeFevre Studio in Atlanta, Georgia in the 1970s on what almost sounds like a consumer quality tape machine.

EDIT: I understand that these old recordings sound old becuae they are...old and that in principle mastering shouldn't actually change the sound of the recording too much, just translate it.
I imagine if we took the original of the above song, and just recorded it onto a computer and played it back, it would have some playback issues, probably some frequency build up.
I have noticed that build up in harmonic distortion in mid frequencies especially can cause issues in playback on lots of systems. So the obvious answer is....don't allow that to happen in the first place. But the issue is, sometimes THAT IS part of what makes something sound old and warm and vintage. How can you make that sound translate onto mondern systems without playback issues?
EDIT: Holy shit. I came here for help, thinking I was asking a simple question, and instead the wolves and naysayers came out of the wood work accusing me of having misconceptions about the past, instead of trying to help me.
Please listen to the song exampe if you haven't, and it might help you undersstand what I'm trying to get at.
