Oh... They did state that the K3 would not support CESSB; however, I have
not seen a retraction of the below note.

It should be possible for us to add CESSB to the KX2 and KX2 with only a
firmware change. We're looking into that, though I can't put a date on it
just yet.

In theory it would make your 10 W sound more like 40 W.
