You won't know how beautiful the -receive- audio is on
SSB until you have the FM filter installed listen

Also running CW here with a large speaker the AGC OFF
try it!

Hmmm... Listened to the audio clip, with the K3 apparently being switched back
and forth between the FM filter and the SSB filter... and I personally like
the narrow-band "communications grade" sound better than the wide-band sound,
with all that high-frequency hiss. Matter of preference, I'm sure. :-) Either
way, it sounds great. Should be another month, and I'll have mine, just in
time for 6m Es season, I hope.

Guess I'll just have to continue the wait for my K3
so I can see how great these things all are.  Of course,
I expected that they would be :-)

I agree with you Bill about the noise-- and my hearing drops off lots at
the higher frequencies.

I can't imagine listening to it very long with good hearing.

I have a Timewave DSP-599ZX audio DSP filter here.  The high and low
cuts are independently adjustable.
It has a range from  100Hz to 5KHZ.  The optimum settings I find here
for normal crowded band SSB condx are low cut =300 Hz and high cut
=2200Hz.  (This is an IC-706 with totally unknown audio response
characteristics).    The fact, that the upper cut is well inside the
passband of the SSB filter indicates, the higher freq stuff isn't adding
anything for me.   It also indicates, I won't be unhappy that the K3
currently cuts off at 300Hz.   (Earphones always used here.  Haven't a
clue about these cut points for speakers)   I'll be anxious do the same
playing around with the K3 when it shows.   I've ordered a 1.8KHz
filter.   These results seem to indicate it may not be "too narrow".

Then again, I'm interested in intelligibility, not fidelity (given my
ears of course).

I'm really wondering under what conditions one would want to use such a
wide filter on for SSB.  Perhaps 10M or 6M  or dead band local
communications?  All the adjacent signals would seem to be really
bothersome under normal condx and wipe out any benefits.  Just curious.
Not interested in generating flak. (Perhaps the PSK crowd who are
interested in decoding multiple signals simultaneously would find it
useful.)

I like the  narrower bandwidth too. Much easier on the ears, especially if
listening for a long period of time.

Yes, these Elecraft fellows really have covered all the bases.
