Reading an interview with Ed Meitner, he stated that Sony and others are archiving their master tapes to DSD format(SACD). If you wait a little while, the pro digital recording equipment for DSD recording will be somewhat affordable for a serious person wanting to archive an extensive LP collection for posterity. SADIE(a pro rec.equip.mfr.) currently has a system out for $28000. I know that's alot but look at what always happens when new technology comes out - prices soon drop. I think that if Sony and others are using this DSD to archive their billions of $$ worth of master tapes, then it's probably good enough for us too.
