1st SACD Purchase

Hi,
Glenn Gould- J.S. Bach: Italian Concerto.Partitas 1&2 (single layer)
Vladimir Horowitz-Chopin, Rachmaninoff, Schumann, Liszt (single layer)
Both from Sony Classical, i've listened to them today-really nice

Pat Metheny Group ECM White album, Keith Jarrett Sun Bear Concerts, Jeff Beck Wired, Blow By Blow, Rough & Ready, Orange album, Todd Rundgren A Wizard A True Star, Something Anything, Santana Caravanserai, III, Abraxas

Along with the other suggestions made, in the classical vein I've been very impressed with the recent Reference Recordings(Fresh RR) SACDs with the Pittsburgh Symphony, particularly their Strauss and Shostakovich recordings.  Also, the San Francisco Symphony's Mahler cycle and other recordings are excellent.  And one you might have to look hard to find is a Harmonia Mundi recording of Manuel de Falla's Three-Cornered Hat suites and Nights in the Gardens of Spain (HMC 801606).

I have them both on cd, vinyl, SACD and stream HQ tidal
SACD best for those albums... Been picking up rolling stones sacd from that there auction site... Search for dsd as people sometimes dont list as SACD so less bidders

One thing that I have found vis-a-vis  CD vs SACD vs High-Res (streaming or on Blu-Ray or Audio DVD) is that it's not so much the resolution that determines SQ but rather the care put into the mastering that matters. Here's an example: 
I have the RCA Red Seal  recording of Prokofiev's "Lt. Kiji" with Reiner/Chicago Symphony.  on three formats: vinyl. JVC XRCD (Red Book). and on BMG/RCA SACD. Both the XRCD and the vinyl sound BETTER than BMG's SACD remastering!  In fact it is one of the best sounding reissues I've ever encountered. The BMG version is dual layer and when I compare the CD layer of the BMG with the JVC XRCD, I'm gobsmacked at how much better the XRCD sounds!
