"We don't hear radio frequencies. My experience is that typical digital falls short of analog at the very top of the audible spectrum lacking in overtones and the natural sense of space."Don't forget that we are listening to an analog format when we listen to AM/FM and SSB. Technically that Icom radio is an analog radio that processes its functions with a digital process.There are digital formats for radio that transmit the typical 1s and 0s and then it's decoded back to analog so we can hear it and the advantage to that is the signal has a much better chance of making it to the receiving end without getting broken up. As hams we can transmit in digital formats in certain areas of different bands but I have to review the band plans..

Absolutely! Which requires an analog output stage and loudspeaker. The Collins one is tube based while the Icom is most likely op amp based.
Lose the op amps!
I continue to observe you are comparing two different things when you first state that a digitally based receiver cannot match the sound quality of an analog one. You could use a triode based output stage for the digitally based radio and most likely, get similar results.

The Collins in the video of course is 100% solid state but has mechanical filters that Collins is famous for..The premises of my OP was to compare older vintage transceivers and radios to newer technology and in this case as we deal with analog radio formats,multiple use of microprocessors can be a detriment because of the noise it generates.Here is inside of the KWM380 so it also had it share of modern technology for the late 70s and early 80s.
