[Elecraft] K3S audio board for K3 upgrade?

[Charlie T, K3ICH]

Using a couple old Radio Shack "Minimus"
speakers, I find the K3s to be the best sounding
and easiest to listen to radio I have ever had.
I agree, the TS-2000 as well as the TS-480, while
an excellent mobile rig, does in fact roll off the
higher frequencies too much for my antique ears.  
This started to happen around the time Kenwood
went to digital demodulation instead of analog
circuitry.

I was on one of the nets the other day using my
K3s and noticed the net control  station was
particularly hard to understand.   I thought my
hearing had gone or maybe I had set some parameter
incorrectly. Then I looked at the panadapter
display.  There was a very pronounced peak in his
audio around 300 hz and practically no energy past
about 800Hz. No distortion, just a widely skewed
audio passband.  It was a boatanchor radio, so
there was something obviously wrong somewhere as
everyone else sounded great.

My gut feel is that the K3s IS an improvement over
the K3 in regard to the recovered audio.

I had a 480 and did not care for the sort of
pinched up audio compared to say the 850. 
I am using a couple of 6 by 9 speakers in
enclosures on the K3, one on each side of the
stereo and the sound is just fine. As they say,
opinions vary and have so many variables like
speakers, what/how/where you operate, physical
hearing anomalies, etc. that audio reviews are
just about useless.
