How many historical recordings do you listen to? How long have you been listening to historical recordings?
It wasn't until World War II that it was possible to record to tape. The Germans came up with that technology. Reissues of "Historical Material" is, and always has been, all over the map. The odds of getting a decent transfer from 78 source material is much greater with digital formats than with LPs. For example, the most recent CD reissue of Robert Johnson's complete recordings from 2011, "The Centennial Collection", has carefully selected styluses, 24 bit recording and sophisticated digital de-noising. It's the best transfer of this problematic material I've heard, and by a very wide margin. I could point to other digital reissue series, like Warner Classics reissues of Arthur Schnabel or their big box of the Busch Quartet, both featuring the best sound I've heard from recordings that I have listened to many, many times. Knowing how the original 78 sounds like, as I used to collect, them my take is that the kinds of tools we now have for editing, de-noising, adjusting eq make the experience of listening to good digital transfers of historical material better than listening to the originals.
As for transferring recordings from the analog tape from LPs, that usually happens when the original tape (or some sort of a tape) isn't available (or someone is cooking up some sort of illegal bootleg off of commercial discs). Most Digital transfers of LP era titles come from the original analog tapes, some from remixes of the session tapes or stems. As regards the remixes, it's a matter of taste if one finds the results superior to the originals.
