MOBILE FIDELITY ONE STEP VINYL

Amazing. I just came from Better Records web site. Did you know that none of us are decent listeners because we have not spent "10 years listening 40 hours a week"??? These people will not be in business long. In doctor speak they are totally FOS. IMHO anybody spending more than $35 for an albums worth of music is being sucker punched. Yes, there are great pressings and lousy ones. Good mixes and bad ones. But you can get the best mixes and pressings for as little as $20. You buy records to listen to the music you like. To have a large satisfying collection. They are a terrible investment and I have no interest in "original" copies. I also have amazing music that is on a terrible pressing or has a bad mix and I enjoy listening to it just as much. Just maybe someone will reissue it in better quality for a decent price. 
It is all just profiteering. Also whenever you see "guaranteed" your BS antenna should go up.     

I view the hot stamper thing as an exercise in statistics with of course many variables...
so finding the white hot perfect sounding both sides pressing out of possible millions is mostly an exercise in futility.

you can of course narrow the search by making some assumptions about mastering engineer, pressing plant, made on a Monday or a Friday, etc....

part of that last bit was a trick question 

Back when I was working, this would have made a nice homework assignment for somebody wanting to get a six sigma black belt.... or not.....

now that I am retired, I think about two minutes about the math and just laugh....

But IF you want a single variable experiment on pressing # SQ, look no further than MoFi..... of course the range is limited, on purpose 

I just came home to an order from Elusive Disc. Paul Revere and the Raiders Spirit of 67. Friday Music. Great mix, almost perfect vinyl, $30.
Andrew Hill, Black Fire. Blue Note. Classic mix (piano to far in the rear)
Perfect vinyl. $35. Brahms Symphony #1 George Szell, Stereorama
Knock out recording. Perfect vinyl $35. Four great records for the price of one One Step. My kind of deal.
