Replacing the caps might give better audio, if the caps are causing a
noticable percentage of the distortion. Capacitors aren't perfectly
linear
and those nonlineararities will cause distortion. Steve Bench has
posted
tests of several caps:

However, the Kiwa article doesn't mention detector distortion, which
can be
a significant source of distortion, at least with diode detectors. The
subject of detector distortion has been beaten to death here and on
other
forums. One post I seem to recall involved some simple mods to a
common
diode detector which significantly reduced distortion but also reduced
output by about 3db.

The Kiwa article doesn't mention detector distortion but it does say:

"High definition speaker wire and gold plated connectors are
recommended for any remote speaker connection"

Thanks for the link showing capacitor distortion.
And I was wondering about detector distortion, and
the distortion caused by crappy audio power ICs.

I will have to wade through ancinet post looking for teh
thread on reducing detector distorion. That strikes me as
a good first step.

The one thing that made me ask quetions was the "high diffiniton...)
comment. That stuff has always reminded me of snake oil.
