Twisted pair cabling is a type of wiring in which two conductors (the forward and return conductors of a single circuit) are twisted together for the purposes of cancelling out electromagnetic interference (EMI) from external sources
Just remember the mains coming in is carried on cables that are sometimes a century old, and are often rather noisy. The high price is just to pay for the advertising.
Topic: Worlds most expensive kettle leads
I have to say that I love music with a passion...I love my high end system but I am not an audiophile. I do see/hear the differences that cables make..
I'd just like to thank neilep for his entertaining insight into the world of high end audio - a good read and a good contribution. Obviously there must be differences to be heard of companies would not sustain their markets, whether peoples perceptions are aspirational and tangible is an interesting debate - what is a significant improvement for some may be negligible for others depending on the outlay. I'd like to ask neilep for his opinion on the power cables. I can see that different speaker cables have different impedance, capacitance and resistance which can colour the transmission of different frequencies, I can hear this in good quality long guitar cables. But what about the power leads? Is it just that having bought a high end amp for £11,000 they cannot face using a £3.50 power lead? Can a significant sound difference really be heard by spending £1999 on a power lead?
This is one of the most interesting discussions on HiFi that I have come across. I think Neil's input is very interesting.
By way of balance, as this is a science website, I can see very little scientific justification improving mains leads. By all means add a filter if there is any problem with noise spikes from other household equipment and avoid "earth loops" i.e. Star connect the equipment earths and have a single ground path. Neil, if you think you get better sound from an amplifier with special insulation, cryogenically treated wire etc. then that's fine, but it is a huge stretch to scientifically justify any of this.
Posted by: graham.d« on: January 15, 2012, 20:16:31 » Neil, I would be impressed if anyone could explain any improvement in sound quality by use of such cabling unless the equipment it was supplying was of such poor design that it was rendered particularly susceptible to the nature of it's power supply cable, which, from what you have said, seems unlikely. However, I do not doubt the honesty of your belief in your observations though would venture to say that the power of suggestion may have come into play. Proper double blind testing would be more convincing. I have to say that if your observations are correct then I am at a loss to explain such an improvement in sound quality. If you have a reference to the special cabling I will see if there is anything more to it that I can see that could provide such magic. I remain sceptical though.As for cryogenic treatment of cable... the mind boggles. What is meant by a more efficient current pathway? I can only think that there is some annealing effect. What could this do to any advantage? It could, I suppose, 1. slightly change the resistivity of the material2. slightly reduce the 1/f noiseIn my opinion, any such change in these factors (and it would be very small), in mains cabling, should not influence the sound of any equipment being powered through it. Any impact from these factors will be hugely swamped by whatever is on the mains supply anyway and/or will be filtered by the subsequent power supply circuits. It may be more effective to get a priest to bless the equipment before use!I bet someone comes up with concrete proof that it all works now I've said all this
Posted by: Bored chemist« on: January 15, 2012, 20:44:23 I have no doubt that Neil's observations are correct. It's just that the reason for them lies in psychology rather than physics.http://en.wikipedia.org/wiki/Suggestion
there is no reason why the amplifier cannot be arranged to have a negative output resistance so that the resulting resistance is zero at the speaker terminals.
Right now all I need is not to have a blown left speaker cos I had System of a Down / Toxicity on tooo loud this morning. For wanton idiocy - I had a valve/tube based ipod dock for about 5 weeks. It was nicked and I spent the insurance on something else and re-used the boring old cheapo old i had for years
I'll stick my neck out and bet a pound that hi fi audiophiles who spend £1000 on a power lead, £11k on a CD player and same on an amp and speakers don't listen to much drum'n'bass or disco tracks in MP3 format

£100 kitchen knife? Really Neil, you have to go up market http://japanesechefsknife.com/SPECIALS.html
no C&W though
