The sounds being described are probably not just related to frequency
response, but to any type of harmonic, intermod or digital distortion, or
noise that is created in the final IF and analog audio stages of the radio.
This was referenced by Rob Sherwood in an early review of the K3 and
demonstrated with an audio spectrum analyzer. A CW tone with these
characteristics might be described as "raspy", "brassy", "busy", or with
some other term audiophiles like to use, and in any case, would likely lead
to fatigue.
If this is the case, equalization may mask it but won't fix it, and could
make the problem worse.

Subject: Re: [Elecraft] K3S audio board for K3 upgrade?
My TS-480 also sounds better than my K3. My K3 was sent back to factory to
see if there was an audio issue with my particular K3. They compared mine
to a factory unit, using an audio spectrum analyzer and noted that my K3 and
a new factory K3 were "the same".
The TS-480 just sounds better to these ears.
Oh, and it is magic........
