The 7700 had no thumping and was pretty good.  (Quiet Band)  So,  I began to experiment to try and understand what was happening with the K3,  and think when the sidetone monitor is set at a certain level,  the thumping is covered up and will not be heard.  But,  then the monitor is reduced below a certain level the thumping will appear.

Here's a "please don't" reply.  I've used a rig that had the sidetone 
track the audio gain and found it very unpleasant at times.  I like the 
current implementation.
