You are definitely not alone. In fact, welcome to the club!
I'd be willing to bet that Kind of Blue, regardless of the specific release, has led more people to question either their equipment, their hearing, or their sanity than any other jazz recording ever made. People tend to assume that Kind of Blue must have terrific sonics because the recording is so famous; however, it's the performance and the place of that performance in the history of jazz that make Kind of Blue so highly regarded. The sonics of the original recording (and consequently all subsequent releases) leave a lot to be desired. Ironically, Kind of Blue is a perfect example of an 'audiophile gotcha.'
It's one of those recordings that may actually sound better on less revealing, lower end equipment.
