Fantastic!  This info is great for me right now since I just started doing
my own wiring on my home-brew signal procesors.  Thanks alot!

For single-ended line-level connections (phone and RCA jacks), a very good
and possibly cheap solution is CAT5 computer network cable.  If you work
around someplace with a computer network, you'll find they often throw
used lengths of the stuff out that are yards long.  It has 8 high-grade
copper wires inside, in twisted pairs.  Don't separate the pairs.

Speaking of RCA jacks, avoid them like the plague!  If you have some in
your system, convert to a decent termination mechanism as soon as you can.
The misanthrope who perpetrated standardizing the RCA connector on the
audio equipment of decent human beings should be tortured, forced to
listen to Barry Manilow, and tortured again.

If your equipment supports it, use balanced connectors.  XLR or 1/4" phone
jacks both work fine.  The whole point of balanced lines is hum and noise
rejection, and they work very well.  If you must use single-ended
connectors, use 1/4" phone jacks, or better yet BNC.  Pro video equipment
uses BNC for sound connections.  It's a solid, constant-tension, low-force
connection designed to be connected and disconnected often.  Moreover, BNC
is so widely used in computer networks that you don't have to pay
audio-industry markup for it.  It's easier to use, cheaper, and provides a
better connection than phone jacks (much less RCA, which is useless if you
actually connect and disconnect regularly).

Audio-grade wire is usually a ripoff.  You're paying for packaging and
advertising, not quality.  Find some well-made satellite dish coax with
and all-copper (not copper plated!) conductor and copper foil shield.
Stranded is more flexible if you need that, but solid-core sounds better.
Wire size isn't NEARLY as much of an issue as Monster Cable would have you
believe.  Wire quality and decent insulation are, though, and there's more
to quality wire than "OFC".

I build homebrew tube audio equipment.  For internal signal wiring, the
best cheap wire i've found is Radio Shack 32ga wire-wrap wire!  It's so
small that it's a pain to work with, and it's impractical for the home
studio.  But it's silver-plated OFC with excellent Teflon insulation
(speaking of silver, use silver plated connectors rather than gold if you
can.  Gold conducts better, but the crap they have to put under it to get
it to stick to base metal does not.  Silver will plate directly to copper.
Again, what looks good and what sounds good are different things)

Don't knock crimping - IF you use proper crimping tools.  A properly
crimped connection forms a "cold weld" where the metals are bonded
together.  But this only works well with high-quality crimping tools and
practice.  You won't get a decent crimp with a pair of pliers, so you may
as well solder.  For soldering, try spending an extra buck or two on
decent solder.  Radio Shack sells fine gauge silver-bearing solder for
little more than the cheap stuff.  Get that, and a tube of rosin flux, and
i *guarantee* you will get better connections!  And learn to solder
right... heat the joint, not the solder.  A bad solder joint will crack
and fail, and can even generate RF noise.

I'm sure it did!
