[Elecraft] High quality stereo cables

Not sure how they stack up on the "quality" scale but I have had good 
luck using 1m stereo cables from RS.  I've not seen RFI sensitivity 
and no failures in continuity.  I recently retired some "cheap" 
computer speakers in favor of West Mountain COMspkr's and needed a 
speaker cable from my KX3 to a four input audio switch which allows 
the speakers to be shared.  I cut off the computer line from the old 
computer speaker and found it was shielded cable.  That's kind of 
interesting since the speakers were susceptible to RFI.  The COMspkr's are not.

I also recently made up a patch cord for my TNC to connect to a "new 
to me" FT-2400 2m radio.  I had to cut up a DB9 cable as I had no 
male DB-male connectors and too cheap to drive 25mi to RS for 
one.  The DB9 was 9-conductor with shield which was a nice 
surprise.  This connected to a peice of cat-5e terminated in RJ45 to 
insert in the Mic and a shielded 2-conductor cable to the speaker 
(mini-phone stereo connector).  No RFI issues seen with this new 
interface cable.

I have had experiences with some of the "commercial" cable makers 
with mixed reviews.  I bought made-up RG-223 cables for repeater 
jumpers which were better than I could assemble.  Duplexers offered 
150 dB isolation so one did not want to destroy that with leaky 
cables.  These were commercial VHF and UHF repeaters, so the firm was 
willing to pay the price for high quality.
