Well, I've been busy experimenting and my new findings are still not carved in stone but here goes: The RR treatment seems excellent for large orchestral works such as RCA shaded dogs with Reiner and the Chicago Philharmonics. There is not only a noticeable difference in width and depth of soundstage between treated and untreated sides of the same LP, but the overall sound seems richer and more lush. Strings and horns especially just seem to have more bloom. A contrary experience was with an old Verve Stereo with Ella Fitzgerald, "Clap hands here comes Charlie", which I had newly bought and where my findings were quite similar to the old Satchmo LP I had written about before. The one side, which I had treated, sounded fine, but there was no real definition of the soundspace of the accompanying instruments. Ella's voice and the rest of the band seemed to be on just one horizontal plane. There was no depth to write home about. The untreated side, though generally more dry in its rendering, showed definite layering of the different instruments, with Ella firmly placed in her own soundspace. The rendering was less lush, but in a sense more realistic with the various instruments playing around her. Also her voice was better definied, much like Armstrongs'voice seemed better to me untreated. So I am still puzzled and will keep on trying to find out if its all in the mind or if there is a reasonable basis to my findings.
Cheers to all,
