I have the Miles Davis Kind of Blue 45rpm recordings from Classic Records and agree the sound is excellent, especially compared to the 33rpm version. I will have to look into more of these recordings in the future.
As for vinyl versus CD/SACD. I recently upgraded my digital front end with TRL modifications (Transport/DAC). I will say that some of the digital recordings now sound very close to analog and have a tendency to exhibit more detail. However, I still prefer vinyl overall, or for that matter 2-track reel-to-reel or DAT masters. There is an ambience that digital just does not quite capture.
