Why spoil your audio system by using iffy phono
plugs.

Is a low-cost plug necessarily "iffy"?

IMO phono plug cost seems almost immaterial to effectivness, some cheap ones
are good, some expensive poor & vice versa.

Phono connection can be pretty variable at the best of times
dependent on the make, manufacturing tolerances etc.

AFAIK the RCA plug/jack was originally used to internally connect a 45 rpm
record player mechanism with a crystal cartridge to a two-tube power
transformerless mono amplifier and 4 inch speaker of such low grade
construction that it is virtually impossible to duplicate today.

That it became the predominate connector for consumer audio is IMO a
miscarriage of justice and technology. The good news is that a proper
audio
system can be constructed today with audio signals passing through exactly
zero of these techno-abortions.

Agreed, but I'm sure the ubiquitious RCA will be with us for a while
yet..mores the pity.

But hey we're
stuck with the phono connection so we'd better make the best of a
'bad' job.

Fact of the matter is that the worst part of the RCA plug/jack design is
the
jack, not the plug. Obsessing over plugs therefore doesn't make a lot of
sense unless it can be shown that a reasonable inexpensive design fails to
pass audio transparently as typically used.

Agreed but trying several different makes of new plug into one jack does
show variability - one new plug I tested dropped out with the jack facing
down! (For test purpose only)

The good thing about RCA plugs is that consumer audio is for most
consumers,
a set and forget thing. As a plug/jack that is mated and unmated a minimal
number of times, as bad as it is, The RCA plug/jack is adequate if
reasonably well-implemented. Since warranty claims are of paramount
importance to reputable manufacturers, the plugs and jacks on most audio
gear in the category we call "mid fi" or better is usually up to the job.

But for high end probably not, because of many physically large heavy
cables...but I'm sure you'll have an opinion on that one :-)

In my time I've manufactured many thousands of phono
cables as a business, in the course of things I've used most of the
more popular makes

Hmmmm.

Meaning I most likely had experience with more phono plug/jack combinations
than the average consumer. Boring but true.

If you want to buy a lot, try Studiospares. They give quantity
discounts.

Thanks, but I already ordered some plugs in bulk from rapid, pretty nice as
far as these things go. I also got a few plastic ones from maplin for about
the same price.

Now I've tried both, as far as I can see/care they are all pretty much the
same. The gold ones were nicer to solder, and could support more weighty
cables, but that's about it.

Has a significent, audiable differences between short phono and XLR

What do you suggest instead? I suppose toslink, or phono used digitally?

Compare and contrast XLR versus RCA

(1) XLR connectors have at least 2 insulated conductors plus ground so they
can be used for balanced I/O. The RCA can't. Advantage - far fewer problems
with hum and noise, particularly in complex setups.

(2) The XLR connector latches in place, so it doesn't fall out of its socket
by accident. The latching mechanism is very robust - you can hang relatively
heavy objects with a good quality XLR cable.

(3) There are no exposed signal-carrying parts with an XLR connectors, so
critical signal-carrying parts are mechanically protected when the plugs are
unmated.

(4) XLR connectors make the ground connection first and break it last. This
reduces noise and transients when you insert or remove them when equipment
is turned on.

(5) XLR connector signal-carrying pins are large and wipe over a long area
when the plug is mated.

(6) XLR connectors are self-centering and self-locating when you mate them.

(7) XLR connectors are very robust - you can step on them, even drive a
truck or run a road roller over them, and they will still work.

(8) Modern XLR connectors incorporate effective cable strain relief and are
easier to assemble than RCA connectors.

(9) Quality XLR connectors are relatively cheap compared to so-called high
quality but poorer performing RCA plugs. You can get a quality XLR connector
from a top manufacturer for under $2 in small quantities.

(10) Quality XLR cables are also relatively cheap compared to so-called high
quality but poorer performing RCA-based interconnects.

What do you suggest instead? I suppose toslink, or phono used digitally?

There's a digital standard that uses XLR plugs. It's called AES/EBU.

Fun disadvantages of XLR in the domestic setting :

(1) When you trip over a lead the equipment comes too.
(2) You need serious back panel real-estate for home cinema.
(3) When plugging blind you need to align it.

Another advantage of XLR (leads):
(1) You can daisychain 'em easily

:-)

For me it tends to be:

1) Due to variations in size, and the design of the inner part of the
'contact' of the female, connections can sometimes be unreliable.

2) The live makes contact before the outer, and is exposed in the male.
This can lead to sudden loud noises if used with equipment on, and can lead
to accidental shorts, etc.

I'm happy enough using them in a domestic context, but given my druthers,
I'd have chosen something else.


Slainte,

Jim
