As far as original issues some have been mentioned already like Supertramp~CotC, Steely Dan~Aja, PF~DSOtM. My original copy of Marillion~Misplaced Childhood is excellent, also The Cars~Candy-O and Yes~Fragile.
Since pretty much all new recordings are saved as 24bit digital masters now, the downstream processing plays a vital role in a new issue sounding "excellent". Whether the format is CD, digital hi-rez file or vinyl...The CD has easily become the lower SQ of all formats today. I have done countless A/B comparisons with CD and Vinyl in my system and CD loses each time....again on my system, YMMV.
For new vinyl issues I'd suggest:
Peter Gabriel's I-IV, plus So and Us. Absolutely steller productions, remixing and cut as 45RPM...
Steven Wilson's The Raven and Insurgentes, crazy dynamics and resolution.
The reissues of Can's Tago Mago and Ege Bamyasi are magical. The bass notes are deep and clean, nothing muddy about the mix, these are all done from the original tapes.
Porcupine Tree, pretty much all of them......Deadwing is finally getting redone for Feb release as well as In Absentia. I have both on pre-order, I have In Absentia original issue and it is already an excellent one, but has been out of print for awhile. Dot3 is fantastic for testing detail of bass notes on ur system.....
There are many others by Riverside, Haken and Marillion. Brave is magical, out of print though, I could get $300 bucks for it prolly....never sell!
Also it does matter your system whether you will be able to hear these records in all their glory, another subject though.
