Theoretically the best sound at 78 would be with a microgroove size groove since it would be capable of higher frequency response then a wide groove, or a microgroove at slower speeds. There was a label in the 50s called Audiophile which produced red vinyl microgroove 78s. When the Soviets started doing LPs in 1953 they issued some at 33 and others at 78. I have about 30 of the 78s. Unfortunately the vinyl used at that time was very noisy. Later on they used clear red vinyl for high quality export copies of widegroove 78s in the early 70s that were sold in the U.S. by Victor Kamkin's. I got copies of them in the 90s. The Soviets released 78s until around 1956 and their shellac was much quieter than the vinyl they used for LPs of that era.

I think but am not positive (and I'm sure someone on this list will jump right in and clarify this) that the Bell Labs 45-45 2-channel format invented in the 30's was for standard wide-groove and 78RPM. I dunno if a modern stereo cartridge fitted with a 78 stylus would read that groove just fine, or if there's some technical difficulty with that. But, more importantly, would you cut this modern 12" wide-groove 78RPM record with the RIAA curve? Is that optimum for that format or are there physical reasons you'd want to use another curve? Being realistic, as far as what's a viable niche market, I think 45RPM microgroove LP is about as far as vinyl is going to go in modern times. It is becoming the preferred reissue format. I have to say, $50 for the typical 2-disk reissue is above my indulgence budget. -- Tom Fine ----- Original Message ----- From: "Aaron Levinson" <[log in to unmask]> To: <[log in to unmask]> Sent: Tuesday, October 06, 2009 1:51 PM Subject: Re: [ARSCLIST] late date 78 > Bob Olhsson wrote: >>> -----Original Message----- >>> From Clark Johnsen: Last time I dared to compare, the Presley 78s (and the Bill Haley, and >>> others) sounded better than any LP issue. >> >> I cut a half-speed 78 acetate as an experiment while I was a mastering >> engineer at Motown and the results were scary good. >> >> Bob Olhsson Audio Mastery, Nashville TN >> Mastering, Audio for Picture, Mix Evaluation and Quality Control >> Over 40 years making people sound better than they ever imagined! >> 615.385.8051 http://www.hyperback.com http://www.thewombforums.com >> >> > The near holographic realism of a mint and noiseless 78 is truly something to behold.
