Just a quick straw poll...

What are people's opinions of mains filters, upgraded power cables etc?

Have been doing some investigation and there may actually be something
in
this. Not talking Russ Andrews style £250 mains cables here, more like
sticking a plug with a filter onto a standard IEC lead, and possibly
using
one of those Masterplug RFI filtered 4-way blocks.

Has anyone done any serious experimentation on this? I did hear a quite
convincing demonstration at the Sound & Vision show in Bristol a few
years
ago, but the mains there is probably a lot dirtier than your typical
home
installation.

What myself and a few others have figured out is that the level of RFI
introduced onto your ring main by something like the switching PSU in a
typical PC is quite high.

Opinions, people?


Hello Glenn. A couple of days ago, I popped in for 30 secs to
an audio demo at a local dealership to take him some audition
material. He was demonstrating a mains filter unit. He had a
tunable RF gadget with a small inbuilt speaker which he plugged
into a wall socket. Radio transmissions and very loud hash could
clearly be heard. Then he plugged the gadget into one of the
filtered outlets. Silence.

The unit was about 4U in height, and had ten mains outlets
on the rear panel.

I was there for only a few seconds, (car parked on a yellow
line) The dealer has promised me some literature.

Regards to all

Yes please publish it here for all the see, and see also what snake oil
he used to do that with.

Total bollockx!.....

OK Tony and the Gang! For your hedification:

Monster Power type HTS 2600.
This is one of the midprice units at about EUR 400 trade.
and about EUR 590 retail.

I have just spoken with the main dealer. They have no
stock, and demand outstrips supply.

The analyser box to which I referred is not on sale through
retailers, though I have seen them previously.

It is termed "Wide Band Power Analyser" and made in
either the UK or the US by a company called Entec.

I don my flameproof overalls and retire swiftly to
a neutral corner.

Over to you.
