I'd like to add my general agreement with this post, with one exception.
I know the RCA Living Stereo series has been reissued to death; I have almost all the current SACD releases, which almost uniformly sound terrific. BUT . . . the idea of being able to hear these performances, many of which still rank as "best ever" (e.g., Reiner's Strauss; Munch's Ravel, Debussy, etc. - and the Saint-Saens Organ Symphony recording is unbelievable) on a 2d generation 15ips tape . . . well, maybe I wouldn't kill for that, but I might rob a store <grin>. Remember that the reissues of these titles were not done using Tim DP's electronics; even the current SACD releases, which I think sound better than any of the previous tries, were done with a Studer deck using solid-state electronics. Highly modded solid state, to be sure, but still . . .
Given how LP fans start drooling over mint-condition "shaded dogs," I wouldn't discount the audience appeal of having a close dub of the original master (mixed to two-channel, of course) - nor would I discount the market impact of having Stereophile or TAS review such a tape and talk endlessly about how much better they sound than ANY LP or reissue in any format. Which they will!
