What were the LO CUT and HI CUT values that produced this "tinny and hard
sounding" audio?

In both my K3s, the audio sounds great and it sounds identical, whether I
use the 2.8 or the 1.8 kHz crystal filter with the DSP LO CUT = 200 Hz and
HI CUT = 2 kHz.  No way it could be called "tinny" or hard sounding.
