Without idiots around,smart guys could never shine.On second thought,smart guys shine with the way they talk and the vocabulary they use.As for respect to other people's views ....

Hi.
A power cord sounds different or not depnds how good is the audio system & how sharp are the ears. A crappie receiver may not show as obvious difference in power cords than a Hi-end amp.
In my situation, I went thru from stock SP-2/3 home-depot type power cords thru resonance damped oxygen-free pure copper cords to now, AWG#12/3C 4N purity solid German silver power cord - airtighted & resonance damped I DIY design/built.
I never look back as pure silver - when handled PROPERLY - makes the music sound so silky & elegant, & holds the music infra details intact from below 50dB to 100dB SPLs that no copper can touch !!!!
Yes, till now I have read very exhaustive measurent report on
different cables total harmonic distortion, phase shifts, I/O wave form comparison using sinewaves & dynamic music waveforms
showed very very little difference, if any, on papers to support the sonic difference many of us can detect.
The report commented on the measured data as "ALL cables yield
frighteningly identical results.."
The report conclueded :-
"It shows that people who claim that cables do NOT make a difference are plainly deluding themselves.
On the other hand, those that say that cables SHOULD not make a different, are dead right."
IMO, cables sound different may be due to the mismatching (O/P impedance etc) of the driver end & the terminating load end.
This should be technically explanable.

PS: I am over 20 years in HV power engineering industries, involving tons & tons of wires & cables. I think I should a bit about cables & wires.

HI.
If one knows the business of wirs & cables, one can DIY design/build interconnects & power cords that sound excellent like worth mega bucks yet cost only very little.
' Cause I can hear the differenct among cables, I custom design/built my 6 pairs of interconnects & 2 power cords using 4N purity German solid silver conductors. I am yet to see any brandname interconnects & power cords built with pure silver conductors. Maybe the prices are so freightenly high enough to scare off any buyers.

Hi.
What more "idiot" can one be by trying to play "smart" on watching from the other side of the fence without actually trying out.
I've tried it out exhaustively before I comment on cables.

Some though,do not seem to understand what you've just said.If comments like the ones we've read above have to do with intelligence and music,then I am happy being an idiot.This was not the first and I bet it won't be the last time I've heard that.I know you've tried it out before.All who can hear the differences did.🙂
Brett said:
Indeed.Have you ever tried it?In post 157 you will see that the cables were also tested on the amplifiers a few days before.
Tried what, blowing $580 on a power cord for my turntable? What kind of a complete idiot do you think I am (or Brett for that matter)? Not a chance. Especially since I can build one for less than $50, and I do think this thread has become absurdly humorous. What's next, suggesting we try one of those insanely priced cords on our passive preamps?
I can buy a perfectly adequate TT PSU lead for less than $1.kuroguy said:
You are correct kuro, this has become absurd.
kuroguy said:
So,you simply can't tell if there is a difference or not since you have not made similar tests.I am building my own power,speaker and interconnect cables for 31 years now.I can accept it when something someone else did sounds better than the one I did. I am also sure that you must have spent more money on something that I wouldn't have done.
You don't have to blow a few grands..
Hi.
to hear the cables difference.
Even cheapie cords from the Home Depots & the Shacls can tell PROVIED, as I already posted earlier, your system is anaylical enough & yr ears are sharp enough to tell.
But if you can't hear the difference, why bother???? A passive preamp got no active stages to be powered. So, no need any power cord to start with.
My question is:- you do know how a cord of different design/built perform on differenet loads? Even a resistor so passive gets different sound, so?

Hello cheap_Jack
I for one would deeply appreciate details on where to obtain
the wire and how you have put it together_assuming that
this isn't a proprietary/commercial product.
Yours Sincerely

Folks .... everybody,
The following cannot be confirmed in practice because of logistics (and does NOT serve to play off personalities against each other - that offers SO little scientific evidence ...) But I would like to ask:
If at least some basic laws of electricity can be accepted, then I believe one can say that elements in series in a circuit (circle) will all pass the same current, as nothing is added or disappears along the way, irrespective of the length of elements (in this case wire).
Then it should be accurate to say that if one installs this superior power cord (say 3m length) somewhere in series with the electrical mains line - say at the power station - the same difference should be audible (and accepting that nothing else draws current from this power line during the experiment).
I am sorry if the argument is old, but I am still puzzled as to how an exotic cable of 3m length can audibly improve sound quality in series with ordinary electrical supply lines of say several km in length? (Locally those are often 100s of km).
Also, if it is true (as implied by protagonists) that better cable works by not influencing the signal passed in any way, in contrast to ordinary wire, why is it that the 'ordinary' mains at the wall socket, can be transformed into 'pure mains' at the other end of said 3m of cable?
This is NOT a tongue-in-the-cheek question as similar words uttered by others very often are. (I do not believe sarcasm has a place in science - or anywhere else.) But I think it is fair to require some degree of logic from acceptably honest experimenters, as completion of their argument before I can contemplate it. The 'level playing field' concept is still valid - it is unacceptable to me to have something handed to me on a dish, violating so much basic logic, without some counter argument. Am I expected to accept the inviolability of hearing never mind how many laws as basic as gravity are trampled on the way? (And please don't tell me you do not know - then kindly go figure.)
I honestly put two options on the table. Kindly explain to me why I should not rather accept that the whole business is simply explained by vagaries of the hearing/testing process.

Re: You don't have to blow a few grands..
You figured that out on your own, did you? A turntable also has no active stages. Just a motor and speed controller.

Re: You don't have to blow a few grands..
The last time, I tried a cable swap, my wife, who was visiting the neighbours and didn't know I was messing with the system (and couldn't care less about audio, except to listen to Michael Bolton), came running home and declared 'my goodness, the system sounds exactly the same'.cheap-Jack said:

A TT PSU is a near constant load. Resistors have know characteristics, but a short power lead is an almost perfect resistor, with a very small amount of inductance and shunt capacitance.cheap-Jack said:

HI.
I just took a common example of a passive linestage. So why you mentioned passive when it was for a TT where you already said the TT motor drive which is NOT passive as active devices are there to control the motor speeds. So it needs to be powered. So a power cord is in the picture. You can hear it or not is up to yr system to deliver & yr ears to tell.
