I have not read all of this somewhat overwrought thread, so maybe my analysis is crocked. I am not an apologist for Mobile Fidelity.
In this pictoral the "Ultradisc One-Step Process" (UD1S) shows the Lacquer derived from the Original Master Recording. The latter is depicted by a hard disk. That suggests the OMR is digital doesn't it? Is there a digital feed to the lacquer cutter? (Note the text above the picture refers to original master tapes.) The above email from mofi customer service states "there is no analog to digital conversion in our vinyl cutting process" and " We do not use digital sources except in cases where the title’s original master was digital itself." The picture does not contradict that - maybe UD1S records use digital masters. The marketing focus is on the step reduction not on the creation of the lacquer. The picture may not be plainspoken but are there outright lies?
The Traditional Three-Step Process shows the lacquer derived from what I gather is a representation of tape and labeled 'source material'. I don't know much about MoFi - was there a time they recorded to tape and produced AAA records? If so, could that be the traditional process?
Does this suggest the writers and the pictoralist are not in sync about the UD1S process? Presumably they are both in marketing. If the original master recording is on disc, maybe the marketing writers don't understand what actually happens if they claim the source is tape, but the one making the picture does. Is this a case where ignorance is mistaken for deceit?
That is photoshopped and not the "official" MoFi literature despite what we've learned this week.
