...have become more knowledgable about quality sound reproduction? Mine certainly have. I grew up in the Sixties and like most kids of that era, lived and breathed rock 'n' roll: the Beatles, the Stones, et al. That's the music I grew up with and that's what primarily appeals to me. Unfortunately, as I've become interested in "audiophile" sound reproduction and have assembled a decent sound system, the inherent flaws of the classic rock and pop recordings which I treasure now stand out in bold relief. More and more, I find myself unable to listen for extended periods to my favorite recordings and am gravitating to genres which, for a variety of reasons, tend to have been recorded (or mastered) "better." For example, one of the best sounding CDs I own is the Mo-Fi UDII of Getz/Gilberto. A jazz recording which crossed over and achieved huge success as a "popular" album in 1963, this would not have been something that appealed to me before I became interested in quality sound. Now, it's one of my favorite albums. I actually *enjoy* the music itself and not solely because it "sounds good." While I lament the fact that I listen to my old favorites less and less, I realize that expanding my musical horizons is a positive consequence of my increasingly critical ear. I'd be interested in hearing others' views of this phenomenon.
