I agree with almost everything you've said 
OTOH, I can understand how he comes to the conclusions he
comes to. As someone with 25 years in IT, I have thrown away dozens
of supposedly competently designed SCSI/serial
cables that don't work. SCSI cables in particular are darn
hard to to get right for the newer higher speeds - and it
all seems to come down to how the cable(s) is insulated.
I also agree that this doesn't necessarily have anything to do
with audio transmission. However, IMHO, this business about
insulation continues to bedevil me. Since it does play havoc
with digital signal transmission, it seems to me hard to leap
to an absolute conclusion that it has no effect in the analog
audio world. No hard science on this yet, but it is a very active
field of research...
