Rodney,I performed these measurements myself. They were published in Popular Electronics, Nov. 1980 issue, "Phonograph Playback: It's better than you think!" p.48 and on.
I have absolutely no doubt of the numbers, or their validity, as I took numerous measurements with many different set-ups.
I think you 12 bits is way to pessimistic, and if we want to talk about the average TT system, or what is possible becomes the issue. My current home playback is capable of more than 12 bits of dynamic range. This implies that any record could be successfully recorde with even the cheapest sound card out there, as almost all "16 bit" sound cards are capable of 12 bits of resolution OR GREATER. Most Sound Blaster 16 series cards are capable of about 14 1/2 bits of actual resolution, which is not really adequate to fully capture metal cassette tape using HX Pro and Dolby B. The cassette tape sounds better than the digital copy, and it is not hard to hear either.
I have an Event Electronics Darla, a "20 bit" home studio grade sound card capable of a real 17 bits of resolution, and it can not capture even most of my commercial albums, much less the direct to disc albums.
Keep in mind that until very recently, most studios only had 16 bits to record with, the actual dynamic range on the commercial CD AFTER limited bit length digital proccessing, AFTER going through a couple of sets of A to D's, and D to A's is no longer a true 16 bit resolution signal any more. Hence the huge popularity and drive to get more than 16 bits of clean recording into the studio.
Now if you have not heard vinyl done right, on a rumble free turntable, on a properly set-up arm, using a wideband MC cartridge, and premium vinyl, then you may not appreciate the full potential that vinyl offered. It is easier with CD to get to the 95% point, vinyl takes a lot more investment of time and set-up and tweaking and just plain understanding what to do, and what not to do.
Half the battle is a good place to set the turntable. I started out m taking my lab measurements with the TT on the rack with the analyzer, I ended up with a concrete re-inforced base next to the rack, and a 50 pound TT base.
