Got a mains cable, don't judge me before you hear what I have to say

RE: don't judge me before you hear what I have to say

Think you demanded an excuse as to why someone's nephew says the word Dude.

Can it stop? This has gone ridulously off topic.  

 

Where were we on the mains cable?

Really? I can think of at least three and that's just members of my family.

Are you related to Bill and or Ted by any chance? I have only ever heard dude used on the television and radio.

No but if I said two them were under the age of ten you'd be getting pretty close to the reason why they use it.

Well my boys are seven and twelve and they don't do it.

I guess they're not watching the same TV shows as my nephews.

How old's the third and what's their excuse?

He's their dad and his excuse is there's nothing actually wrong with the word, so what's the problem?

If you have to ask, you wouldn't understand the explanation.  Hellfire you are a strange one!

Seriously, you prefer a discussion about mains cables to this?  puzzled

  The fuse isn't there to protect the equipment. It's to protect the cable (and you from it). Audiofile fuses are of coarse pure bull though....

Fuses are used to prevent abnormally high current (which could be drawn from a defective load) from both fire and safety perspectives. It's certainly not there just to protect that cable specifically.

Also, in the case of mains cables/plugs, the statement that the weakest/noisest/thinnest link in chain underlines the performance for the end user is not applicable in the arguement of whether they 'improve' performance for ampliers etc... It's not like data transfer.

Expensive mains supply cables might well propose they reject the high frequency signals from the 50Hz, which would be perfectly true. The arguments should focus around whether or not the cable 'improves' the signal as such that a) they are significantly noticable, b) applicable to all households and c) a 'cleaner' signal actually benefits the device at all.

Any scientific facts to counter my statements are welcome.

RE: Got a mains cable,

If these cables "reject" rf signals I wonder what they do with them?  Perhaps it goes into the wallets of the people who make the cables?  But I guess those are quite full anyway.  rolling on the floor laughing

Now if you look inside any peice of electronic equipment you will see in the power supply a bloody great electrolytic capacitor which is connected from the +ve power rail down to earth.  The resistance (impedance) of capacitors is inversely proportional to frequency so they have infinite resistance to DC voltages and have diminishing resistance to AC voltages.  The main function of the capacitor is to remove any vestige of 50Hz voltage left over from the rectifier part of the power supply.  Now you can imagine that if it is good at removing 50Hz voltages it is bloody good at removing RF voltages.  If it were for example VHF voltages (that used in FM radio) these range from 30MHz to 300MHz this capacitor would be from 600,000 times better to 6,000,000 times better at removing it.  The point of this preamble is to question whether even if these cables do dimish rf signals this matters in any real sense because any rf signal is not going to get past the power supply.

It's just O Level (O levels were like GCSEs except they were hard) physics.

if the fuse was in the cable to protect the equipment, then it would not be necessary to have internal fuses. In most of the world there are no fuses in the plug (yes, I know they are radial systems with a trip at the consumer unit) but your equipment would be fried long before the trip or indeed plug fuse went. Plug  fuses protect kettles, not Hifi.

Try me.

I've thought of a fourth person actually, my old supervisor when I was an electronic engineering apprentice used to say it all the time, I probably did as well thinking about it (so that would be 5). Must look him up, haven't seen him for years, very poor of me...

I ask in all innocents about bi-amping my new speakers and nothing,then i read this thread!!

...w.t.f. dude!! Cool

RE: don't judge me before you hear what I have to say

yes does make you wonder doesn't it.   Just out of interest I used to have a big old battleship of an AV Amp an Onkyo 905 which is a 7 channel amp and majorly beefy and ran that using 4 of the channels to bi-amp my front speakers and very good it sounded to.

Must've wondered three times over, but that was a very fine amp, still is in fact I think.  Wouldn't turn my nose up at a 905 at all...
