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
