A couple of thoughts:
1. This is about misleading marketing practices...not which one sounds the best. A One Step could be made from an 8-track tape dub and may be the best sounding ever. However, the box needs to say the source and signal chain for such expensive pressings.
2. Analog vs Digital. My guess with today's digital converters one would need to hear the original master tape and then a flat transfer(DSD) from that tape. Any sound quality differences at the consumer level probably has more to do with the mastering tweaks and/or format (LP, etc) and it's inherited sound charactoristics.
