DIY Interconnect questions
as for rca's check out either the wbt-0101's or 0108's
and the eichman bullet plug.

Oh yes, more cable questions! Let the flaming begin!
Seriously folks, I've been planning on making some more cables (have done
so
in the past), and was wondering about the relative technical merits of
shielded
two-conductor cables vs. shielded single conductor (esp. coax), for
unbalanced
runs. What I did in the past (with Belden 8761, I vaguely recall) was run
signal and ground along the two conductors, and connect the (foil) shield
to
the ground at one end only. This 'shield-attached' end was plugged into
the
(integrated) amplifier for all components.
Now I'm thinking here that I've got a twisted pair for induced-noise
cancellation plus a 100% coverage foil shield, and a fairly low
capacitance
value (something like 25pF/m). Should be pretty good, right? However, am I
in any danger of causing problems by having both centre conductor and
shield
tied to ground? I _think_ that having all of the shield-attached ends on
the
same component should avoid ground loops, but I can't quite puzzle it out
in
my head. One question that comes to mind is why do almost all except the
most
extreme (weird) high-end commercial interconnects use either coax or at
least
single-conductor-with-shield geometries? Another one is am I mucking up
the
low impedance factor by wiring it up this way?
ON a related question, does anyone have opinions about good RCA
connectors?
Ideally I'd like a split pin, a locking ground cuff, and HEAVY gold
plating
or maybe rhodium. As far as I can see though, Cardas is the only company
that makes rhodium plated plugs, and they have neither the split pin or
the
locking collars.
Thanks,
Colin
