Thanks for the suggestion, but no, that is not at all what I meant by 
"muddy." I know a 60 Hz hum from wall wiring, and this is not that 
at all. When the music pauses or there is a rest the stereo 
becomes totally silent. Totally. No hum at all.

What I am trying to describe is what your speakers would sound 
like if you stuffed pillows into them -- muffled, high tones clipped, 
inadequate definition, no brightness, horns sounding like they were 
in the basement.

I think it's some kind of a mismatch. I know if you plug a 4-ohm 
headset into an iPod that expects a 32-ohm headset the fidelity will 
suffer. This is sort of what I am thinking might be causing the 
problem. But I don't know enough about how these things work.
