[QUOTE="JimJ, post: 3729146, member: 555251"] I don't get what you're saying...lively and laid-back? Most FM processing involves compressing the signal, so they can maximize modulation into the transmitter and seem as "loud" as the next station, and limiting the peak level so they don't overdrive the transmitter input and introduce distortion. Also, because of the way FM stereo multiplexing works, there's a 19.5KHz carrier signal that your receiver needs to seperate the left/right signals - so FM stations have a very steep low pass filter in order to make sure that they don't have audio going up that high, or you get a "chirping" of the stereo signal. The end result of all this is that most FM broadcasts are loud, but lack dynamics and the full spectrum of sound...much like a bad quality MP3 that's been boosted or cut to equalize an entire album, to put it in that context. What kind of references do you have for what's "good sound" to you? [/QUOTE]
