To which I would add...while we believe we can get the best from any
original, I always keep originals simply because I believe there is
always
the possibility that technology will give us better capture in the
future.
I would hate to think of some lacquer discs being tossed after transfer
considering some of the possible use of the imaging technology for
capture
becoming economically viable in the not too distant future. Perhaps we
could have, or perhaps there is, some technology to capture, without
direct
contact to a playback head, audio from magnetic tape.
As for what you keep, versus your available space...that is a rough
question at any time...
