You're right indeed!
Now 11 deg N and 100 deg E is a place where the band conditions rarely
exceed those of the 60's so my KWM2A still holds up well most of the
time though I wouldn't use it in a pile up for a new one or a contest,
for sure you then see it fall flat on it's 50's designed faceplate. As
to the filter, again, no good in EU today but in the right environment
it still has a certain something. Hard to put the finger on.
I never liked the look of the Eagle. Great performer though it no doubt
is. Put it in a bigger box with a Collins S line style front panel with
more knobs and I'd probably buy a dozen, heat not required!

As nice as its audio was, the KWM-2 would not be very good with today's
crowded bands.
The famous "Collins mechanical filter" was not really very good by today's
standards.
A 4-pole crystal filter on 455 kHz is as good or better and of course you
can buy 6 or 8 pole filters now.
And the DSP filters on lower frequencies are even better, sharper, and have
steeper skirts.
As long as we're dreaming, I wish I had 1960's band conditions again!
All things considered, it's hard to beat the Corsair with its combination of
good audio and good crystal filters.
Newer radios have better filters but worse audio.
For my money, the best compromise is the Eagle.

I've long liked the analogue radio sound. So far my all time fave, just for
the audio, is a KWM2 with that big 6x4 speaker, something about that warm
sound seems magical. Next up from my current radios would be my Omni V. Not
sure how that might differ from the Corsair but whilst generally pleasant
it's not in the KWM2 league. Then the Orion 565 and Elecraft K3, bit of a
mixed bag these two as they are both very variable but I've not yet been
able to recreate the analogue sound. I might need to experiment with
amplifiers right at the point the signal becomes analogue. A god analogue
audio amp with LTP input and complementary pair output in discrete silicon
feeding a big speaker, might sound very different.
The TS940 had good audio too but for me about the same as the Omni V

I have a Corsair II with the DDS VFO, which works nicely. I think
it's a single conversion though.
Normally it converts to 9MHz, then to 6.3MHz, and then back to 9MHz,
unless you bypass the 6.3MHz PBT i.f. which can be done fairly easily
but you lose PBT and narrow filters and don't gain much.
I agree on the CAT comment. I always dreamed of adding a CAT port to
the DDS cpu firmware.
