When the selectivity is way up front, the later stages introduce their 
own broad band noise, all the way to the audio output amp, and digital 
artifacts from DSP contribute a lot to that. Many a receiver can be 
helped by a passive low pass filter on the speaker or headphones. One I 
developed years ago is at: 
http://www.geraldj.networkiowa.com/papers/speakerfilter.pdf It has 
selectable cut off frequencies but it adds virtually no noise in the 
stop band. It improves even the Corsair II.
