>>>   ?Now, what about a good cheap supplier?

The problem with many so-called "CAT5 installers" is that there
are a lot of
cheap ones out there who will not fully obey the specifications (which
include things like minumum bend radius on "behind the wall"
wiring.) As
such, a lot of "so-called" CAT5 installations will work fine for
things like
10Mb/sec data, but fall over a year down the line when you try to run
100Mb/sec over them.

I'm not sure what level of sophistication you actually need for balanced
audio though - does anyone have any experience?

The other thing to be careful of is "CAT5 UTP" vs. "CAT5
STP" - the U and S
stand for "Unshielded" and "Shielded" respectively. My
personal opinion
would be to use UTP unless you have a really nasty emf situation (this
like a blast furnace, not like a mains supply), and then use optical fibre
instead. UTP is much cheaper, but still a lot more expensive than

I must confess that my home system installation still has trailing flyleads
taped to the skirting boards - not exactly wife-friendly for most people,
but fortunately, I married a VB developer ;-)
