I was on Pipex 1Mbit (fixed) paying £23.44 - moved to Sky (potentially
up to 16Mbit, but in reality due to line length / noise i'm getting only
4x the speed of my old line, but at only £10 per month instead.

It doesn't beat it in direct terms, but the £/speed ratio is about the
same :-}

Might be because of the price of the scraftsmen - it's a rare trade
although numberous machines are also quite unusual. I suspect the

I notice that you can save £1000 by having a socket put it so you only need
the 1m cord rather than the 2m cord.
I assume the user is just going to get an electrician in and fit a 2.5 mm
spur using £1 worth of T&E rather than the £1000 a meter cable.

I am surprised that this expensive high level kit the users buy has such a
poor design and such cheap components in them that adding a filter to the
mains lead makes any difference at all.
Maybe its to improve the sound from an ASDA midi system?

Good gracious no, one would use the Superior Ring Main cable with 16
Hyper-pure copper conductors insulated with Teflon at only £4,200 for
a 100m drum.

For sockets one would use the SuperSocket, a snip at only £25.95 each
as they are specially treated with DeoxIT™ PowerBooster to maintain
their performance and keep them free of oxidisation. Choosing the
earth terminal option lets you add an additional earth for your
system, improving bass performance and the soundstage.

Obviously one would use a couple of UltraPurifier Platinum Edition
superior passive differential and common mode filters at £450.00
each.

If an extension lead is required the Ultra PurifierBlock-Ag is a
pretty good bargain at a mere £1,185 as it gives you four sockets and
makes your music more rhythmic and musical. It also gives you
clearer, brighter pictures with more saturated colours.

This would easily leave you with enough in the budget to pick up a
couple of 11 ft lengths of speaker cable at a mere £20,640 for two.

(I'm guessing battery, with enough volts to be connected in place of the

There are instances when mains hum does occur due to ground loops. These
can be fixed with sensible audio cabling and on a balanced system you
can lift the screen at the signal source end of a line-level cable. For
completely awkward electronically induced hum and noise (like a laptop
connected to your hi-fi!) you can use a pair of audio isolating
transformers as available form Maplin (Bleurg!) at a modest price. (Go
for the car audio ones where they are paired in a plastic tube with a
pair of phono connectors at each end.

There are some in the professional audio industry who are so utterly
clueless that they actually believe that "lifting the ground" means
cutting the earth wire in the mains plug! This is a great way to kill

Oh dear. There appear to be people still doing it.

So you have equipment with floating mains earths and you have earthed
equipment. A fault occurs, someone bridges the two pieces of equipment
and gets killed.

You NEVER disconnect the mains earth from equipment. It's a very
misguided bit of technical folklore that has already caused several
serious accidents. The correct way to lift ground on a balanced system
is to disconnect the cable screen at the source end of the cable so that
the input device is providing the screen reference.

If you do disconnect equipment earths in the way you've described and
someone does die you will be held accountable for their death and will
face a charge of manslaughter.

No - it earths via the screen on the connecting cable.

Balanced system? With correctly designed balanced connections you won't
get an earth loop, even with separately earthed equipment casings. That's
why it's used on pro equipment. I'm talking about unbalanced domestic.

I can't access that video. However, most of these sort of accidents happen
because the location mains supply is faulty. So the correct approach was
to use *mains* isolating transformers. And always was. Although these days
RCDs take care of the safety angle.

screened TP cable is a good way to get earth problems especially when its
100+m and terminated in different buildings.
once you understand how to deal with that audio stuff over a couple of
meters is easy.
Just keep a soldering iron and some ceramic caps handy.

Most decent workshops should have a mains isolating transformer
available. Mine has. ;-)

I have one

I've still disconnected the scope earth from time to time


Haven't looked recently, but they are similar in looks and price to a
110v site transformer - if you want a portable type.

That's an electrical workshop environment. Besides the correct
procedure is to use a mains isolation transformer where possible. These
days I use a battery powered scope.
