Here’s a question. Were any of the DCC pre records remastered and or recorded at 18 bits?
These days old analogue tape masters tend to be copied at 24bits which is I guess a kind of future proofing, but unless the DCC release was a new high bit digital recording, I wonder how the old source material was treated.
My guess is most DCC tapes would have been produced from whatever digital copy the record company made available and that these would have been CD ready but not necessarily DCC ready.
I’d be interested if anyone knows for sure.
