[Elecraft] K3:New APF what happened?

[Larry - K2GN]

Let me state right up front that my CW is bad, mostly because of an ear
problem.
But my decoder software allows me to operate CW fairly well.

With that said --
Unfortunately, I stayed away from the previous beta version and sat back to
wait for this new version. Now, I don't have a comparison.
I was expecting something more than I got.
I have yet to find a signal that really "pops" out at me.
Yes, it helps on some signals but not on others.
In fact, due to the "ringing" or hollow sound, the weak signal is better
copy with normal operations. If have I/II so I can switch back and forth
quickly.
I use the 400 narrow filter.  NR,NB, etc off.
Anybody have any suggestions that can bring this station up to what others
are reporting that they experience?
