It must have been the clicks and pops that confused her. Who could have known that you could get $2500 for a power cord that makes your system noisy....

I can't see a "UL" approved on it. I wonder if that's an extra charge?

Every power cord in my house is gold plated. I have a gold plated plug on my soldering iron as it helps it get hotter. My 'scope seems far better at measuring since I fitted it with a gold plated power plug. My broadband modem goes faster now I have plugged its wallwart power supply into a gold plated noise filter extension cord. I have endless examples of the wonderful effects of gold plated power plugs. Could you possibly be suggesting that I and others have been duped by unscrupulous manufacturers that are just out to relieve us of our hardearned ? Shame on you, disbeliever !! :-)

Every so often a discussion of surge protectors pops on the technical mailing lists I'm on. I am against MOV type units because IMHO they provide little protection, stop protecting without warning and can catch fire. I'm not joking, there are several documented cases of them making a loud noise and the plastic case they are in burning here.
The next step up are the ones made by Trip-Lite and sold under the brand name ISO-BAR. They sell for around $50-$60 from mail order discounters and retailers in the U.S. The patents on them have expired and instead of cheap knock-off's showing up, a company has made a unit with the same technology targeted to the audiophile and large screen TV market.
Their unit is well over $300, sold mail order.

Ahbutah.. is it oxygen free gold?
I once upgraded a girlfriends jewellery from plain silver to gold and instantly discovered an improvement in her performance

I recall reading, quite some years back, that MOVs have two behavioral characteristics which tend to cause these problems:
- When they're forced into conduction by a voltage spike which exceeds their standoff voltage, the varistor structure is usually changed in a way which reduces its ability to stand off subsequent spikes. In other words, their standoff voltage is permanently reduced.
- After multiple conduction events, a MOV will tend to fail into a "shorted" state - its standoff voltage drops below the line voltage. I haven't found a manufacturer's data sheet which explicitly confirms what I read, but anecdotal reports seem to suggest that it's correct. When MOVs are used, I think they should *always* be placed behind a relatively fast-acting fuse or circuit breaker, so that when they do fail (and short out) the fuse will blow quickly. Putting them directly across the line, with no fuse/breaker protection, tends to lead to the sort of !BANG! and puff of foul smoke you have experienced.
Some power strips just use a small fuse in series with the MOV itself... which means that the power strip will cease to protect (either silently, or with an LED that then goes out) if the MOV shorts and blows the fuse.
At least these use metal cases! They still seem to use MOVs, and Tripp-Lite's FAQ admits that they can lose their spike-protective properties over time.
I seem to recall that some company (and I *thought* it was Tripp-Lite) had a spike/surge suppressor which used across-the-line SCRs or triacs, with a specialized gate-trigger circuit rather than MOVs. Such a device, built with hefty-enough thyristors, wouldn't be subject to the sort of per-spike degradation that MOVs seem to suffer. Expensive, though!

Wimp - I have solid silver cable throughout the house and had special cable laid in all the way from the power station. Can't understand why DAB still doesn't sound like a CD.

To e-mail, change noise into sound.
AFAIK they work by using an inductor and capacitor network to slow down the pulse enough to allow more robust, but slower devices to work.
Trans-Tector uses avalance diodes. They are extremely expensive, and market their devices as power and communication line and antenna "protectors" to places that are exposed to lightening but must continue to operate such as airports, etc.

No question about it.
Failure to do this would fail IEC safety regs.

That sounds scarily like what a believer in gobal warming would say if you suggested the whole thing was a crock of shit !

I suggest exactly that on a daily basis, and you know what ? I reckon a few former believers are just beginning to listen, and perhaps changing their views just a leedle on eco-bollocks ...

They go to $99
Remember these things ??
Like a Cd? Where are your standards? You're supposed to be improving it to the point where it sounds like an LP.
Snap, crackle, pop...

No, that's CE.
