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:

selectable cut off frequencies but it adds virtually no noise in the
stop band. It improves even the Corsair II.
