Can't speak to your current or future thinking Gary, but...
The K3 and K4 [and some other non-Elecraft radios too] are near the physical limits for most of what we consider important today. Not going to get much better because of that, and who's at the top will depend for some part on the quality of the test equipment, the quality of the tester, and the roll of the dice. Cryogenic cooled front ends next? The odds of someone coming up with a dramatically, no fooling, real advancement in ham receiver performance are lowish, at least in my likely lifetime ... and, I live in Nevada and odds are an important part of our state income. [;=) For now, I've decided to keep my K2 and K3, they seem to be about as good as it gets, and I know how to work them.

Reading the Sherwood tests today I noticed the K4D tested ranked below the K and K3s and I started to look at the data published and I am still a little unsure of why it scores lower having assumed it would be significantly better in performance over the K3 and K3s. Perhaps somebody could point out to me if I am not seeing what is important. I believe in if I can hear them, I can work them but like most folk I like a quiet noise floor and a comfy buffer of audio over noise. My current thinking is hold onto my K3 until the K4 is improved as my upgraded #679 has served me so well and is the only transceiver I have ever loved and kept. It's not going anywhere soon hi hi.
