Tim, as long as you listen to the PRO receiver with either phones or
speaker through the crappy internal analog audio system you will not be
getting anywhere near the sound that radio is capable of producing. I have
heard that the PRO II redid the audio output section completely - hope so,
because it needed it!

I suspect that is the source of most of the audio fatigue you are

Any sort of small amp into a 8" speaker or larger in a decent sized
enclosure will show you the difference.

My PRO is far quieter than the analog, non-DSP, crystal filter IC-765, but
that is because of how I handle the output audio, as we have discussed
privately in detail.
