I've had numerous K2s and K1s over the years. Other than tiring audio (to my ears) at times they have been amazing.
And now I have a brand new KX3 on the desk. Wow! My only antenna at the moment is a 17m doublet tacked to the ceiling .... and the KXAT3 tunes it up on 40-10 without straining. Great receive audio.
Now I need to get the CW and Data working.
And get that 160m antenna back up.
And maybe a loop for 40-10 somewhere.
And ... operate this thing. :-)
Have a great day all.
