I agree Peter. 

If distortion occurs in front of the filters, there can be horrible 
distortion yet nice narrow bandwidth.

On the opposite side of the coin a signal that sounds very clean on 
the operating frequency can be very wide.

One has nothing to do with the other. How you "sound" on the 
operating frequency doesn't always have anything to do with 
bandwidth. That is why an oscilloscope can't tell you anything 
about bandwidth.
