So on the MoFi website, it seems as though the one steps are the records affected by the digital process. They discuss the ultradisc Gain 2 process and there is no mention of digital DSD, only on the One Steps. They use a Studer tape machine Etc. So those are probably all analogue. They do say super analog.
MoFi controversy
I see this hasn't been mentioned here yet, so I thought I'd put this out here. Let me just say that I haven't yet joined the analog world, so I don't have a dog in this fight.
It was recently revealed that Mobile Fidelity Sound Labs one step LPs are being cut from digital masters (DSD) rather than being straight analog throughout the chain.
Here is one of the many Youtube videos that discusses it
To me, it seems that if MOFI is guilty of anything, it's "deception by omission." That is, they were never open about the process and the use of digital in the chain.
One thing to mention is that hardly anyone is criticizing the sound quality of these LPs, even after this revelation. Me personally, I wouldn't spend over one hundred dollars for any recording regardless of the format.
