Several weeks ago I asked if capacitors could make that much
difference

in intelibility and that such a simple question would move me to
complete,
then redesign a project from over 20 years ago.

I found that on weak and noisy signals capacitors can make a world
of
difference. A little scrounging has given me a Pioneer KEHP9500
MOSFET
automitive stereo unit, with very low distortion when operated below
10W
and a set of Minmus 7 speakers. And 10W in 2 speakers is painfully
loud.

I brought the audio straight out from my R2000 and found that by
bypassing
all of the audio chain the audio was much clearer. 2nd best was to
use
the
Rec out. The difference here is slight and I wouldn't swear in court
that
I am positive.

Did you crack open your R2000 to bypass the
audio chain?? Sounds like the Rec out is pretty
much a line out.

I then compared the detector direct signal with different types of
capacitors. And Craig at Kiwa is mostly correct. My only
disagreement
is with the Panasonice bypolar electrolytics. I douldn't hear any
diffrence bewteen
them and "good" single ended caps. Perhaps my samples were bad. And
all
electrolytics sound worse then mylar and related caps.

So you replaced the caps in the audio chain within
the receiver to discover this, or did you use an external
detector at this time??
