Brian,
 
My HRO-16 (and the HB companion HBT-90 transmitter) are my main CW  rig.  
The HBR-16 has W3NQN passive audio filter that does an outstanding  job 
narrowing the passband without any ringing.  I highly recommend  it.  Ed also has 
a SSB version of the filter, but I can't speak to its  effectiveness.

If I  remember him rightly, Carl KM1H, said that selectivity gotten with
tuned  circuits, I.F. strips, not crystal filters or Q multipliers, leaves
the  signal sounding better. Certainly the high Q devices like crystals tend
to  "ring" a lot at narrow selectivity settings. Any  opinions?

Cheers,
Brian
