Nonsense.

If it costs the earth it must be better...

Why else would they produce oxygen free signal aligned kettle cables for one's hi-fi...

Because some gullible twat will pay for it?

Here's a good cut and paste on this subject from http://en.wikipedia.org/wiki/HDMI:
"Cable price gouging

Opportunistic cable manufacturers have marketed electrically identical 6-foot cables for as little as 10 dollars, all the way up to 200 dollars. Because the digital datastream is less susceptible to interference than its analog equivalent, the picture quality is similar on properly functioning cables, regardless of price, especially for short cables."

I've heard that gold pressed latinum has even higher sonic qualities but you primitive hu-mans haven't discovered it yet...

Do you want me to tickle your ears?

[TimberWolf]

Yellow paint maybe?

Yeah, that could work. Supercooled yellow paint.

[AtW]

Sceptical about 22 caret gold plating? Me too, surely 9 caret would suffice?

And their optical cables are cut out of real diamodns for better light passing...

The Maplim HDMI cable connectors are 22 ct gold plated for better conductivity .. that is why they are so expensive.

Gas tube arrestors let in spikes of 100's of volts for a few microseconds. Enough to fry modern equipment but save a 1930's phone from fire.

didn't realise we had a load of ex GPO engineers posting on this site???

Anyone else had ADSL filters die on them? I have had 2 go completely dead ... can't work out why a solid state bit of kit should have a life expectancy - both supplied by BT and last just over the year!

I was getting a kind of intermittent white noise on the phone. I thought it was either my knackered old phone, or the dodgy extension wiring, but I noticed the other day when the ADSL was trying to connect the noise started at the same time the ADSL would being it's retry.

So the answer to that is yes. Not completely die, but it's obviously not filtering correctly if you can hear the ADSL signal on the phone. I'd had that one 3 years; new one and no more noise.

To go further off topic a minute: the reason I was fiddling was because I'd had enough of WiFi and bought a couple of Netgear powerline connectors. One end of it is a combined ethernet link and power supply for a Netgear router (so you don't need an extra plug), but with that powering my Netgear ADSL router the ADSL refused to connect. With the old power supply it would work fine. I'm guessing it must be a noisy power supply and that kills ADSL even though the router itself was working fine.

Spikes on the line? Lightning?

aren't broadband phone lines 18v? be interesting to know what the spikes are up to... can't correlate death of ADSL filter to lightening strikes - but annoyingly it wasn't at the same time or on the same socket.... is there a bit of kit to smooth out the electrickery gubbins coming in through the BT line?

Mine came from Demon and died after a few weeks. I put it down to silent, invisible lightning occurring twice on different days (it was either that or the little goblins coming back and I promised I wouldn't see them again).

You just answered your own question.

I went to the local Maplin store to buy an ADSL filter the other day. They were £1 something off the likes of e-buyer, and £8 from the shop.
