What's the deal with Mobile Fidelity Labs "Original Master Recording" UDCD CDs

I have that CD. It sounds nice, but so did the early CD. It is not compressed like the remaster from 2007. I think the MFSL remastered CD has an edge over the original US CD and is set as my primary version, but unless this is a favorite album and you find faults in the other versions available, it isn’t worth the price it currently fetches.

Some of the MFSL CDs sounds significantly better than an original CD release. Sometimes not. I have been disappointed in quite a few while some are my absolute go-to remasters.
