Records are being made. I suggested a 200gram one sided 45 rpm. What would be the method of recording the ultimate LP? What form would it take.? Certainly cost would be o object.
Off the top of my head:
A 180 gram pressing will be better because current presses have trouble with 200 gm and Q/C suffers eg. otherwise MM would have done their BN at 200 grams.
80% of the sound is the choice of recording venue eg. finding something like Kingsway Hall in London for classical recordings would be nice. In other words, getting the sound right before the recording rather than today's correct it after the fact attitude (in large part driven by orchestral costs). For jazz, a small intimate club-preferably a live recording.
Find the optimal miking pattern for that hall. Overall, I prefer Wilkinson's Decca tree configuration (
http://mixonline.com/recording/applications/audio_decca_tree/) for classical. RVG's technique for studio jazz -- but overall prefer live jazz recordings because of the ambience.
D2D might give the best sound but there is the artistic and length of sides consideration.
2 track, one inch tape, 20 ips, Tim's EQ curve. Alternatively, KOJ's special focussed gap machine.
Minimal number of tape generations.
Released on 15 ips reel to reel tape.
180 gram single sided (you know that EMI's test pressings used to be single sided--and they definitely sounded better than the regular double sided issue).
45 rpm (though one might want to experiment with 78 rpm stereo--not such a wild idea)
Limited number of pressings/stamper.
