Didn't know that about radio stations. But the argument I've always heard for why compression is done is specifically for stuff like radio stations, where you want to make sure everything is loud, and loud as or louder than everything else.

If the PCM signal generated by the redbook audio on the CD is clipped, then it'll try to drive your amp with that signal, causing the amp to clip (not due to hitting the ceiling, so perhaps I should not have used clip), and then possibly damaging your speaker, no?
Yeah, radio stations are more than willing to compress music themselves as it is a very simple process if you aren't worried about introducing other artifacts.

As far as a source clipping and it being transfered through the amp: I don't think this form of digital clipping is harmful to the speaker. From what I understand, and I admit a lack of knowledge in the area of amplification as currently my focus is speakers, these are two different phenomena due to the way an amplifier itself acts when it clips versus the way it acts sending a clipped signal. So a source clipping isn't detrimental to speakers while an amp clipping itself can be, but isn't always. Think about how much trouble most speakers would be in with this current compression trend in the industry if this really did damage them.
