Addendum: I just learned that when Bernie Grundman did the speed-corrected new mix and remaster of Kind Of Blue for Classic Records in 1997, he ran the 3-track 1/2" master tape right into the mastering console, bypassing the normal step of mixing the multi-track master and making a new 2-track production master, which is then send to the mastering console. That’s one reason why the ’97 Classic Records pressing of Kind Of Blue sounds as good as it does.
Add to that the fact that the upcoming Analogue Productions LP’s is being pressed with Clarity vinyl, and done at QRP---which produces LP’s superior to those made at RTI (where the Classic Records KOB was pressed), and there will soon be a new standard in KOB sound quality.
By the way: For those who always make the argument that an LP now pressed from a 60 year old tape cannot possibly sound as good as an original pressing made when the tape was new, know this: during the round table chat on YouTube, Grundman explains that most multi-track masters---including those of Kind Of Blue---have been run only once since the time they were recorded, and that was when they were played during the mixing of the 3 (or more) tracks onto a 2-track production master. After that, master tapes are stored and never again touched, the 2-track production master being used forever more for all purposes.
Grundman then goes on to explain that master tapes, stored properly (as Columbia Records and now Sony have)---do NOT deteriorate from the mere passage of time. Please re-read that sentence; the common wisdom that magnetic tape deteriorates with the passage of time is a MYTH! The only thing that causes magnetic tape deterioration, said Grundman, is replaying it on a tape machine. The KOB 3-track master tapes have sat untouched and unused their entire life, with the exception of when Sony brought the tapes to Grundman in ’97, when he did the mixing and mastering for the Classic Records reissue. There is no reason the upcoming Analogue Productions reissue of Kind Of Blue will not easily surpass not only all previous reissues, but also Mint original pressings.
If you don’t think an individually-handmade LP, mastered and plated by masters of the art and science, and manufactured out of Clarity vinyl pressed on a machine which has been lovingly optimized for ultimate sound quality, and separated from the Earth on vibration isolation products (discussed and explained in the video), if you don’t think such an LP can and most likely will sound better than a mass-produced LP, made out of garden-variety vinyl in a facility optimized for units-per-hour yield, then perhaps this LP is not for you.
