John,
You said it is there with and without the KPA100. Have you physically
removed the KPA100 and tried it with just the base K2?
If not, please try that. Should the base K2 be clean, re-install the
KPA100, but after it is installed, remove the right side panel and
fold/tuck the ribbon cable and the speaker cable into the area near
where the ribbon cable attaches to the control board.
Often such a watery sound is caused by coupling from the ribbon or
speaker back into the KSB2 board - dressing the ribbon and speaker
cables away from the KSB2 fixes it.
That is at least a starting point.

There has always been some watery distortion on my SSB signal from my
K2/100.
It is there with or without the KPA100.
It is there with three different mikes.
It is there with two different KSB2 modules.
It is there on both upper and lower sideband.
The CW signal sounds pretty good, no obvious problem.
The SSB distortion is not real bad, but noticeable.
