Please don't let anybody educate you about 'inductance' and 'capacitance' of cables these are the jargons which have been misused or rather abused to make us part with the hard earned money ...
I [dis]agree

. Actually, I think the education is very important, but only came to that conclusion in recent years, before which I just believed the audiophile marketing.
Let people educate us about these things. They are important, and they can make a difference, but the last person I'd trust to tell me
how much difference is a cable salesman. Especially a cable salesman who sells
obviously snake-oil prodcuts (Hello Audioquest and your network-cable nonsense!).
Now you will bite me

hyeah: but recently we tried different power cables on a Marantz AVR. All the cables sounded different in Music as well as Movies keeping everything in the system unchanged. Again these cables were not cheap to expensive but more a less same priced stock cables.
I once
thought I heard a difference when swapping a power cable
Of course, the forum member doing the swapping did, and believed that I would, and I had already certainly heard a difference in swapping a power supply.
But, as my signature indicates, and as I have said many times, I believe that we must enquire into the processes of hearing and psychology
inside the head.
This topic is beaten to death every time. So if we stop discussing this, will be good for everyone.
It will certainly be good for the cable companies never to be challeged.
It is proved that if you use the same power cable brand ,you are going to feel the difference even if it is not there any, because human mind behaves in that way.
I think it is "proved" that there are many, many reasons why differences are heard between components which have little or nothing to do with the components themselves. I think we need to think beyond the kit.
Thats why double blind tests were performed and result were obvious.
It is true that, one is going to hear the difference and this creates many cable believers in audiophile world. So no point in arguing that,
Yes!
only thing to be considered is , speaker designers and amp designers considered these exotic cables as snake oil and among them is renowned harbeth speaker designer and owner Allan Shaw. Because these people are the real time creator of audiophile equipment and if you look inside any speaker , there are very thin wires of normal copper and aluminium surrounding crossover circuit.
To be fair

... Of those I have I have read, there are
some designer/engineers that "believe" in different cables. It is difficult to be dogmatic on this, because, even in following links on the net, one tends to end up reading the same stuff over and over, whereas other stuff might be there too.
But, on the while, basic engineering would seem to be the arbiter, and it is, mostly clear.
How about the idea that the more cables make a difference, the more broken the equipment is?

Ouch. I can hear the screams, but yes, that idea is certainly out there, amongst technically informed people.
1)Human mind hear difference whether cable is same or different(time and space)
The most importand cables are
inside your head! 
hyeah:
2)Every audio grade cable is same if it is made of oxygen free 99.99% copper purity ranging from 10USD per meter to 1000000USD per meter(Anaconda oil).
Same goes with power cable.
And even "audio grade" is starting on the slippery slope. Audio signals are not nearly as demanding as video cables, let alone stuff that we have to leave the house and look in laboratories and industry for.
3)Rather than spending on cables , suggestion given by Mr fantastic and Mr. Ambio followed will keep one happy(content) lifetime.
:clapping:
Works for me (or would if I had money to spend on audio these days

).
After the decades of trying to be an audiophile, I have now come to the conclusion that buying
end-to-end transparent is the way to actually be one. More screams, because people so much love the fiddling, but hey,
It is still not a simple path because what is transparent? And what is not? Will the manufacturers tell us? Not when they want to sell us more and more even within their own ranges.
And, when it comes to speakers, even the most hard-line objectivists seem to agree that all bets may be off. We who are never happy
just listening to music can still have our experiments and debates over speakers and headphones even if we have the rest of the chain transparent.
Alan is yet to prove all amplifiers sound the same.
His experiment is flawed to begin with. Instead of 'his' cheaper amplifier conforming to the reference, he chose to limit the true capability of the reference amp to comply with his inferior amp. That is like asking Germany to play football with 3 player against India or Msia's 11 to prove all teams are equal.
Looking at another test,
Carver tuned his amplifier to win the challenge of making it match, subjectively and objectively, the much more expensive test reference. To me this says two things: one is that
all amplifers don't sound the same, because they are not designed to, and the other is that, in the absence of engineered-in tuning or actually faulty design/manufacture, maybe they could.
If I were to restart my hobby again, I would still audition several cables before making a choice. Would I look at Belden? No. But I would definitely try Audiocadabra. Sometimes, we are just right even though we cant prove them under DBT.
I might have been buying business-critical cables from Belden for years, but would it have occurred to me to buy audio cable from them? Never! Until today.
Now I realise that it is them, and similar companies that must be doing the genuine $$$million research and development in real labs with real scientists and working on cables on which infinitely greater demands are made than audio signals can make.
This is part of the audiophile myth: people see the requirements of transmitting music signals, analogue or digital, along a cable as being some sort of highly-demanding process, and those cables as being some sort of peak of technological development. It isn't and they aren't.
Another reason I'd now prefer to buy cables from one of the manufacturers like Belden... Will
UnicornSeek Cables explain, for instance, what the skin effect is and why it is irrelevant to audio cables? Belden will. And do.
Get the best within your budget but don't use them as a tool to improve your sound.
Bring back tone controls. Cables are not equalisers.
