What kind of power cord comes with expensive gear

In DBT you can never prove the null (that there's never a difference), only fail to reject it. It's like trying to prove a negative: it can't be done.

DBTs are meant to see if there are small differences that can be detected. Those small differences aren't easily picked out due to lots of reasons: room interactions, training, acuity, speaker placement, resolving power of system, etc.

Small differences are harder to quantify but are there, nonetheless. Not being able to put it into words doesn't mean it doesn't exist. Those small differences can haunt you as the gestalt of the music can mask the effects. With so much going on in a performance the ability to pick it out every time isn't possible but it's felt.

No one here can argue that we can pick out a difference visually more easily than aurally and yet we don't do it reliably each and every time, yet the differences are there ALL the time for us to see. Has anyone addressed the aspect as to why our brains don't process the very same info in the same manner every single time?

Placebo affect places an undue and inevitable stress on the evaluator that can never be erased from the equation. Casual listening is a much easier way to detect differences. We are not on guard, adrenalin levels are normal.

Formula meant to specify inductance, resistance, etc as pertains to a music signal being transmitted over wire are standardized. Can anyone tell me if the formula assumes that only copper wire is being used and not aluminum, gold, bronze, etc.?

What kind of insulation was used at the time of the standardization? Is it assumed that only one type is to be used or are small variations in metallurgy and insulation a given as long as they fall into the formula?

What happens when other metals are introduced into the equation? As I remember, all metals are not alike. There is a reason why they are separated on the periodic table: each successive metal had one more proton than the one preceding it. Wouldn't that have an effect on signal transmission, albeit a small one? Wouldn't a purer form of a metal give it a slightly different property? Mixing metals certainly would.

On other threads here it has already been established that what makes science so great is that it is disprovable. There are no absolutes. Never.

I know I hear differences in cables. Having someone point and pound on a piece of paper that has some formula or equation doesn't sway me in the least. Maybe my ears are better than theirs. Maybe it's just that my system is more resolving. Maybe I don't have unresolved issues that would bias my hearing. Who knows?

There is a difference, small that it is but enough to change the flavor of music

since many components are cable sensitive, it makes sense not to select a cable which will significantly affect the performance of the component.

purchasers usually have their own preferences. component designers cannot predict the tastes of their buyers.

thus it makes sense to provide a line cord which is inexpensive yet passes the current required for the component.

Being a member of an audio club , I've participated in a hundred and one blind tests and I could pick out most cords without difficulty , it's really not that difficult if you know what to listen for . Try it for yourself someday you might learn something .

Schipo you just lost the farm again .

everytime u picked out in a blind test with no problem most power cords without diffculty? Not at all thats just bunk and I can smell it miles away...the stench is high in your corner and as I stated earlier. Your mommy must have told you that you were special..your not.

Schipo , to bad your ears aren't as good as your nose .
Many people can't hear small changes in audio , I guess your one of them , nothing wrong with that , but getting rude and insulting is just plain childish .
Is that the way you want to depict yourself ?

Aftermarket cords are the best Dude!!

How many of you aftermarket PC guys rewire your house power system feeding your sound system with a dedicated and clean earth of suitable diameter like say 35 mm sq cable, cos if you don't do something about the power supply putting a monster power cord onto the system will do nothing more than make it easier for the junk in your mains to get into your system (maybe that's why it sounds more "colourful" with the big thick lead!!

You are only replacing a meter of cable with a flexible bus bar system what are you doing with the mains are you spending thousands on power conditioning equipment and filtration before you plug your lead into the power or just using the mains as is with all it's crap and harmonics from all your neighbours switch mode power supplies?

I use a 3 Kva UPS with good filtering on my system simply because I don't want to blow the processor in the telly which is probably the most expensive collection of chips in the house ;) The amp runs tubes and is direct wired inside open ended triode with no printed circuits. I see no need to spend mega bucks on a piece of copper for the mains as the volt drop on a meter of lead is sweet FA unless you are drawing enough current to heat the lead up,the resistance of your mains lead will be well below 1 ohm even if it is 1.5 mm sq cable and as most of your amps are drawing less than 500 watts of power which is on our mains of 230 volts is 2.2 amps give or take a milli amp or two which come out at less than half a volt on the lead with a monster lead you will reduce that to about 1/8th of a volt so your lead is gaining you 3/8 of sweet FA volts and you think that is going to mske a difference to your performance. pull the other leg it has bells on it ;)

Drjaym, that would be the case of resistive load but linear power supplies draw narrow spikes of very high amplitude current causing much bigger voltage drops than one would expect. Also, they pollute with noise as much or worse than switching power supplies.
