Ignoring whether one cable sounds
"better" than another, I'm not convinced
that they even sound different. I'd be very interested to see results of a
proper double-blind study on whether there is actually any audible difference
between cables as you state. Aside from ultra-crappy unshielded cables, or
ultra-long cables, I very much doubt that any human can reliably distinguish
any two audio cables.
The problem is, ultra-crappy and ultra-long cables are standard, as they come
with consumer-grade kit. Anybody who gives even the slightest damn about audio
quality should replace them. However, you don't need anything fancy: if you're
paying more than ten quid, they saw you coming.
But they don't sell medium priced cables any more.
They do, but not in the major consumer stores. I?ve seen very civilized cable prices even
for harder stuff like HDMI and fiber, via mail order.
I tend to repurpose the crappy cables for S/PDIF
and composite video, neither
of which need such a wide SNR, just so long as there's not too much attenuation
at a few MHz.
The problem with consumer stuff is you get a new standard every week with a new cable.
I am sure that you had better connector out in the 1950's than the 5 cent RCA stuff,
but it cost a good bit more.
Ben.
But the 5 cent RCA connector does just fine for that. Better conenctor in the 1950s? Not
clear. ?UHF? is mechanically slightly better than RCA but electrically not really. And
by the way, Heathkit used RCA connectors in their transmitters, so they apparently judged
it to be acceptable for 30 MHz, 100 W.
It?s surprising how simplistic a connector you can get away with so long as you?re below
microwave. F connectors aren?t much, either, but they are small enough that they don?t
cause trouble. (Anything that?s no bigger than a few percent of wavelength is just about
invisible electrically.)
