Of course it probably is a matter of taste for the most part, and also a matter of just how badly you have treated your ears over the years. On the FM side, I really like the processing that the Wolf does, even if I am not a country fan. The Mountain sounds perfectly neutral, which was great for AAA, but maybe not so much for a putative classic rock station. I really think we have a bunch of stations run by professionals, and most of the processing sounds pretty decent to me. Sandusky is the only chain I have issues with- I hear what Bob hears on 92.5, 98.9 is awfully mushy and lacks much stereo separation, and 106.9 truly sounds the worst (to me) of any legitimate full FM signal in Seattle...it was so bad in my sampling tonight I am not sure whether it was processing or something else in the audio chain...in this day of digital pretty much everything, not sure where old fashioned analog distortion creeps in, but that sure seems to be what I am hearing.
KIRO FM has excellent processing for speech, but nothing can make Dori listenable. Nothing.
101.5 has an interesting approach, with a very light touch, but I guess it is working for them, as their numbers certainly seem pretty decent. I assume it is a conscious decision. And they have a very clean sound.
Of course, this is all immaterial- the question really should be- "Which station really brings out all of the nuances of Kokomo?"
