Oh yea, I forgot about the 107.7 days of the X. Their lack of sound quality was a major reason I quit listening to any of the stations. I even went so far as to call to complain, talking to an engineer there who told me there was nothing wrong with the way they were sounding; it was "just fine".
I always blamed the poor SQ on low bitrate compressed audio on some music-on-disk system, but when they switched the X to 100.5 they sounded a little bit better.
Was it that, or processing alone, or both? Never been able to figure that one out. (I'm an outsider so I don't know much of what goes on in this technical area.)
