I have the Bill Evans box set of 45rpm pressings from Analogue Productions. It is a treasure trove of jazz, and it even includes the Cannonball Adderley "Know What I Mean" album with Bill Evans (probably my favorite of all the wonderful albums in this box).
I've only compared a couple of the albums to their 33rpm equivalents, and I think the 45rpm versions give it that extra layer of realism.
Ditto here. After hearing a few superb 33 rpm Bill Evans reissues on Riverside, I was quite skeptical about the 45 rpm reissues, but I am a convert after acquiring a 45 rpm copy of "Sunday at the Village Vanguard." The sound has more weight as compared to the 33 rpm pressing, which certainly contributes to that extra layer of realism you perceived. The air, detail, subtlety, it's all there, but the 45 rpm has that feeling of closeness that 33 rpm lacks. Highly recommended.
