Yes, I'd use BNC for audio connectors (something others have done) if I
was going to change connectors (or building something new) and probably
more important, if this pile had included more female connectors.


I've used them for DC power too, sometimes. Given the quality of the pin
surface and material, and a teflon former, this isn't a bad idea, it's likely
to handle surges better, and more safely, than many connectors intended to do
it. You mention a DB25, another favourite for me. So many pins, each can
handle over an amp, some will handle 2A each. For specialised heavy current
situations, (perhaps up to 25 A with the better ones, it can be much cheaper
to do it that way than with dedicated high current connectors, and it's far
more compact too, and the flexibity of the cable is usually better too. (And
tens of yards of that cable got thrown out during various company somputer
refits, more than I ever imagined any use for). When Maplin did a closing
deal on a bunch of metal hoods I bought 40 of them. I doubt I'll ever run out
of those, or have to spend any money on more except on occasional need for
strange angles in tight spaces.
