I've been meaning to comment on a few of the posts in this thread for a few days.
Stevie Wonder SACD's:
I bought Innervisions and Talking Book on SACD. Songs in the Key I bought on BR-A. IMHO, they all sound as good as I've heard them sound.
Innervisons I've owned on LP, CD, MoFi Gold CD & Japan SHM-SACD. The Gold CD was head & shoulders above the previous versions. SACD was markedly better than the Gold CD.
Talking Book I've owned on cassette, LP, CD & Japan SHM-SACD.
Songs in the Key I've owned on 2 LP (w/45), 2 CD & BR-A.
I highly doubt that Music of My Mind (w/Superwoman) will be out anytime soon on SACD. In 2010, AF released a Gold CD. A few months ago, I bought a sealed Gold CD for $19.99. Perhaps it was from Music Direct. Obviously, it wasn't a huge seller on regular LP, CD or Gold CD. It is wonderful and I strongly recommend it for the best sounding version to date. I've played the Gold CD at least a dozen times and a/b'ed it to Motown's original CD release. I've owned this on LP (x2), CD & Gold CD. This was the album released just before Talking Book. It is ALL Stevie, except for a guest musician on two tracks. The music is great and moves into the direction of what came after.
Love Haviing You Around:
Regarding Jefferson Airplane:
I bought the SACD of Volunteers and it is the best fidelity of any version so far. Still, I prefer to listen on the CD-4 LP I received a promo of back in the day. I've owned Volunteers on CD-4 LP, CD, Expanded CD, MoFi Gold CD and CD (no bonus tracks) in 10-CD Columbia Woodstock Experience box. Gold CD comes closest to SACD in sound quality.
The Woodstock Experience box includes each act's complete live set from Woodstock plus 1969 studio albums from JA, Santana, Sly, Johnny Winter & Janis Joplin. Each was also sold as a 2 CD individual version.
Surrealistic Pillow is a great album, perhaps JA's best. I've owned it on LP, German CD, expanded CD & RCA Gold CD (includes 2ch & mono mixes). I've been debating for months about buying the mono SACD. The Gold CD sounds pretty damn good and includes the 2ch version, which I prefer to listen to.
SP was recorded in '66 by a band that did one great album (Takes Off) that sold marginally, at best. After that, Signe Anderson, the girl singer and Skip Spence, drummer left. Signe to have a baby and Skip to start Moby Grape. Sometime around then, Matthew Katz their manager left, as well. Although SP is recorded pretty well for its' time, RCA was not going to devote the maximum tracks which their studios could record on something that might not sell by a group of five people.
I'd love to see ALL the JA & Jefferson Starship Quads re-released on multi-channel SACD's. I'd be first in line for those and the solo Quads, including Hot Tuna.
