True indeed, so far most of the measured testing done
at the ARRL and their peers is focused on the RF
signal handling traits of a radio, little or no
testing is done with overall RX system distortion of
complex (voice type) audio signals. Nor is there any
meaningful measurements done to determine the overall
contributed noise of the RX's RF/IF and AF stages. The
tests they do are very valuable, but they only tell
half the story of how a particular RX really performs.
That unfortunately leaves some very measurable
parameters up to subjective interpretation.

I would love to have all of the current radios on my
desk to play with and compare. Maybe when I'm rich :).
My experiences with the Pegasus have been similar; it
is clearly the best sounding and least fatiguing radio
to listen to in my shack. It's too bad that I can only
offer my own subjective view of the Pegasus RX audio
quality and not any hard numbers to support it.

True as well. Again part of the issue is that
parameters are being left to subjective
interpretation, things that can and should be being
measured. In reality the only things that should be
left to subjective analysis are items like cosmetics
and many of the ergonomic considerations.
