A.J. van den Hul: Going Dutch Page 4  My best wire, MC Silver,
has three different layers of Teflon film around the wire and
runs flat up to 22GHz! And it's just a multi-strand wire with a
single line in the center in a braiding. People working with
this wire have said this is the very best they have ever
auditioned. This is a new standard in audio. It is very
expensive to make but on the other hand I am quite sure that
when you get this wire, in 10 years you will not have a better
wire. It will keep its quality over all that time.  One of the
things I think associated with good quality is to use a
balanced, rather than a coaxial, line. Cheap wires are always
coaxial and we learn to live with it, but coax has one negative
aspect: the signal-up line is different from the signal-down
line, which has two functions: shielding and transport. And
signal transport and shielding should be kept separate. If you
want to do two jobs with one thing, one is always not done very
well. Coax may be a simple way of connecting
