I was about to buy a copper cable for my Hd-25, but then I took an a... nevermind. I did a blind test, with my girlfriend replacing the copper cable of the HD650 with the stock steel cable on the HD-25.
I was doing a lot of tests myself with these cables and was pretty sure I heard a big difference, mainly the sound being warmer and more pleasant. This is where the placebo kicks in, copper being a softer kind of metal than steel, also having a warmer color, are the things that are attributing to the placebo I think.
Anyway the blind test consisted of about 10 random cable changes with me pointing out whether it was the coppor or steel, and I was listening to a very familiar song.
In the end I lthought the steel cable was the copper one.

Burden of proof lies on the cable pushers. I said I was skeptical. Placebos have been proven to work. There have been a large number of experiments that proove the effect of a placebo. You have to do an ABX test blind.

I can't, other than running some ABX tests. I doubt you have done one objectively. Meaning you can't see which you're using. There's no reason for copper-cableA to outperform copper-cableB. Seriously very, very little EM in this scanerio.

You are correct in shielding not interfering with an optical signal though, unless you plan to run that optical wire right beside a power plant.
Really? You think that EM interferes with photons on a macroscopic scale?

We do know though that light does travel in concentrated lines when in laser frequencies (as used with optical cables) and when bent at hard angles and depending on construction of the conductor, may suffer greatly from reflection, refraction and lose signal strength as well as timing when the same signal is sent on many paths due to these factors.
Light exists as both waves and particles. No? Where were you taught?

It's not enough to deserve military grade cable shielding and braided cables. It's simply ludicrous to assume a 10ft copper wire could pick up such a large amount of EM. Cat7 can go like 500-1000ft, and it's not even that shielded.

I have very little knowledge in "optical data communication", but I definitely understand the basic concepts of light and EM. Don't inult my intelligence.

Ya, but I'm thinking there are very, very few errors. I could see composite getting a few more, but come on.

I thought jitter was correctable by software?

I'm simply saying that this high end cable thing is a big money grab to me, and whether or not that last little tiny bit of radiation changes the signal a teeny-tiny bit is irrelevant.
What is relevant is that that reduction in interferance is perceivable, or just thought to be perceivable through the placebo effect.
Is this kind of a "you gotta have faith" sort of deals? I'm not into that.
I beleive that the cables won't be audibly different, that's all. We are in disagreement and it's not going to change. I think we can drop it.
