Oh, John you're such a controversialist.
I must add that I was a great skeptic about hearing the difference between cables.
I have been accused since of having confirmation bias among other psychological
problems since I have changed my stance.
I change my mind because i heard the difference, and even swapped the cabled over about five times to confirm my discovery.
I believe that some people can't hear the difference because either:-
1/ theyre tone deaf,
2/ they've never trained their hearing to discriminate sound to such a fine level.
Some people are completely colour blind, some are partially colour blind. I have heard a husband argue strongly with his wife that there was no difference between two pieces of fabric. He said they were the same shade of blue, while she maintained one was blue and the other was blue/green.
Could not that be the same with hearing?
I've had a part-time DJ play a CD and a minidisc for me while I had my back turned. He reckoned there was no difference in the sonic quality of them.
I correctly stated which source was being played with a 100% score.
And no, they were not being played alternately.
I have a Sennheiser Lucas surround sound unit.
To set it up you adjust the unit in setup mode until you hear the sound produced coming directly in front of you.
I find it hard to set up for my hearing because about three settings are around the right place, but none is exactly where it should be.
When I listened to music through it, I had no problem hearing the soundstage, and all the other effects were easily recognised.
I hardly use it because I can hear a distinct loss of fidelity through it.
This loss is on par with the difference between the standard cable of my Sennheiser HD600 and my three aftermarket cables. Cardas Zu Mobius, and Equinox.
The Zu Mobius being silver definitely sounds brighter. Some would say tinnier.
DBT testing? That's a little difficult by yourself.
I laugh at that report of the coathanger wire being better than monster cable.
I looked up the site once where it was reported, but could find no info on who did it, where it was done or under what conditions it was conducted.
But then again, I guess there are people who would write out a statutory declaration that their buds they got with their ipod sound better than a good decent mid-fi headphone. If it was a Grado ....................
