Hi, just to try and keep this a bit less cryptic:
note:
"pre-echo associated with conventional lacquer mastering are eliminated and transient response is greatly improved. DMM record pressing sound brighter, cleaner, more detailed, with 15% more playing time than with lacquer technology. Stampers are plated directly from the DMM Copper Master, eliminating two of the three plating steps required for lacquers."
AND
"direct metal mastering (DMM) : A system for cutting a metal mother on a record mastering lathe, eliminating the lacquer master and metal master steps. Release pressings made from a stamper are thus only two stems from the DMM and thus have less noise and distortion than those made by the older, five-step process. The DMM process is also used in CD mastering."
Also:
"DMM is a modern process, developed by Teldec in Germany. Rather than cutting a lacquer, then plating, then creating a mother then stampers, you use the DMM cut disc as the mother and create stampers directly from that. Hence 2 steps saved. So, the theory is the steps saved lead to fewer "generations" in the record-making process, hence better sound."
No misinformation this far as i can see.
My own information is derived from the current (non-metal master) of the Pallas press-plant from an article in Image HiFi some time past.
I think the mis-information is about 'metal-masters' (i.e. not master*ing*?) of the pre-tape , so:

will provide some, if not most of those pre-tape aera answers.
Greetings,
