I want to know the answer to the following question:
What would offer the highest quality transfers of historic interest?
All the background I'm provided with is that "Where old disc recordings are considered to be of artistic or historic interest, from before the era of tape or where no tape master exists, archivists play back the disc on suitable equipment and record the result, typically onto a digital format, which can be copied and manipulated to remove analog flaws without any further damage to the source recording.". Is that enough to answer the question?
Answer: no
