[sdiy] why not to use rca connectors

[Fdi]

The RCA do not short terminals. You can't have normalization but otherwise
they are fine in my opinion. They are very reliable. I'm even planing to use
them.
BNC are a nightmare, personally, I avoid them anywhere. In a modular you
would have one cable failure every two days or so. The conector is fine but
the way the cable is crimped or soldered is very poor. On a modular it would
be a suicide.
1/8'' should be fine if QUALITY male and female would exist, but this is not
the case.
1/4'': there are quality male and females but they are heavy and too big in
my opinion for a modular, and they short terminals when inserted.
XLR are great but obviously too big and bulky.
Another possibility are the so-called mini-XLR form Switchcraft, the real
name is Tiny Q-G you have them in 3, 4 and 5 poles. I think I will use them
for sending power to external modules like joystick, etc. The chasis-female
is a bit bigger in diameter than the RCA.
I'd love to use banana conectors, but I'm worry about not using a shield.
They heve the advantage of, after a huge planetary disaster or the like you
will be able to use your sinth , just plugging any conductive stick on to
it.  =:)
But still fear of no-shield.
I insist, I do not see any problem for the RCA. The are shielded, good
quality available, reliable, easy to clean... just that they have not a
switching circuit
