Thanks Keith, that's good to know. I only have two other rigs to compare my K2
with and they are older rigs that I bought in the eighties. I believe they are
both single conversion designs and I swear that I can sometimes hear weak
signals better on them than on my K2 but, the K2 has much better filtering.
Maybe my brain does a better job of filtering.

I've done this, or as close to it as I can get. Yes, there is a big
difference.
I hook up 2 rigs to the same antenna and then feed their audio outputs
(speaker outs) into a mixing board. I adjust the audio to give the best
S/N ratio on the rig and then trim each channel on the mixer to get both
rigs at the same level in the headphones. I can then listen to one rig
or the other (or one in each ear) by just sliding volume faders up and
down or hitting a mute button. In this way, I'm using the same antenna,
tuning the same signal at the same time and listening on the same
headphones. The only difference is the rig itself.
I've done this test with various combinations of R4A, 2B, IC-735,
TS-830s, TenTec Omni V, K1 and K2.
What I've found is that the differences between rigs are shown more
clearly with this sort of rapid A/B testing. You can really hear the
differences in AGC action, IF passband width, frequency response,
distortion levels and general grunge or harsh sound. There really is a
difference. No, we are not just chasing numbers.

If a ham were to sit down in front of all the top rigs, blind folded and
not allowed to touch them, would he or she be able to pick out the one
with the best receiver by just using his or her ears?
... is there really a difference in the lab numbers as close as they are
or are we just chasing numbers?
