Can't answer your second question about the fans, but I initially
thought that my K2 "just sounded 'nicer'" than my K3. It's not a huge
difference, and I'm fairly deaf anyway, so I don't have a definitive,
iron-clad answer but:
1. I usually use lightweight headphones [single narrow metal band] with
the small foam covered phones on my K2 and a Heil Proset I got from
Elecraft on my K3. When I finally tried the lightweight ones on the K3,
the sound improved. I tried a very old Sony headset [1960's from a
reel-to-reel recorder] and it too improved the sound, at least
subjectively. The K2 sounded about the same with it. I've concluded
that the radio-headphones are a system and the components work together.
2. Jim, K9YC, gave me some advice on the RXEQ, the most important of
which was ... "go very slowly while adjusting it." Make a change, and
then use it for awhile. That stopped my flailing around with it, and I
found I could improve the audio quality noticeably. My current
settings, which I haven't messed with in several years sort of roughly
mirror the response of a couple of "programs" in my hearing aids. The
differential gain achievable in the K3 RXEQ is much less than my hearing
aids, but somehow, it smooths out the sound. [That's a technical term
used by someone who doesn't really know what's happening. :-)]
My observations are mainly for narrow BW CW, I've listened some on
sideband, but not enough to figure anything out. My K2 does not have
DSP, and I've wondered if the less-square response of the crystal filter
isn't part of the equation too. The K3 DSP seems like a brick wall at
times. Maybe someone with a DSP K2 and a K3 has some observations.

My guess is that the K2’s curve is skewed toward the
lower ranges. 2. I have never set the RX EQ in the K3 – it’s
still on what it was when I bought it. Has anyone tried to make a K3
sound more like a K2? If so, what settings do the best?
