Hmm, interestin thing about compression. I understand you're not interested
in XM, but I have to "rant." I picked up my XM radio a year or so ago. It
was Alpine's XMA-T200RF unit. It came with an FM modulator to make it
co-exist with stock systems easier. I, too, could hear the compression
artifacts. I believe some stations are dynamically allocated bandwidth and
suffer from compression less.

Anyways, I decided to crack open the XM receiver and tap into the line
outputs (that go to the modulator) and run them to my stereo. It could be a
placebo effect, but it sounded better. Going direct got rid of the FM
bandwidth limitations. Again, this could be purely subjective, but I didn't
notice the compression artifacts as much.

Just my two quid,

Bypassing the FM modulator and plugging direct will restore channel
separation, dynamic range, reduce distortion, reduce noise, and restore
freq. response (as you mentioned). Good move, that.
