Interconnect Directionality


Have I lost my mind? I swear that I am hearing differences in the direction I hook up my interconnect cables between my preamp and power amp. These are custom built solid core silver cables with Eichmann bullet plugs. There is no shield so this is not a case where one end of the cable’s shield is grounded and the other isn’t. 

There are four ways ways to hook them up:
Right: Forward. Left: Forward. 
Right: Backward. Left: Backward
Right: Forward. Left: Backward
Right: Backward. Left: Forward. 

There is no difference in construction between forward and backward, but here are my observations:

When they are hooked up forward/backward there appears to be more airy-ness and what appears to be a slight phase difference. When hooked up forward/forward or backward/backward, the image seems more precise like they are more in phase. The difference between forward/forward and backward/backward is that one seems to push the soundstage back a little bit while the other brings it towards you more. 

What could possibly cause this? Does it have something to do with the way the wire is constructed and how the grains are made while drawn through a die? Am I imagining this? Have I completely lost my mind?

.... it is the pundits who need to take said blind tests and prove they can hear a difference ...
Nobody here is obligated to "prove" anything to you or anyone else. Of course, you’re not obligated to accept any of their representations, either. This is a hobbyist’s group, where everyone is free to share their experiences.

Beware the audio guru.

I am willing to test on any system you wish to configure ...
Let's see if the group can agree about what that system might look like. Then you could try to assemble something comparable at one of the major audio shows, and invite Audiogon readers and others in to participate.

jetterI have no ideal why what I believe is a small group of persons on A'gon would think that blind testing won't yield fair and impartial results. Please do not repeat the GK arguments against it that the testers are going to rig the test.

Nothwithstanding the fact that the conclusions are sometimes dubious, there have been many perfectly valid listening tests. Because it's such a time consuming task from the onset, organizers who actually go to the trouble of conducting such tests typically put extra effort into making them valid. That's pretty well established.

You just assume I have never done these tests. I have, and more ... I am not under any illusion that all the typical measurements done fully characterize an amplifier. It is one of the reasons why I designed a specific piece of test equipment for a customer ... IF the direction of a cable, independent of a shield is as plain as the nose on my face, then surely it is dead easy to replicate this, blind tested?
Here we go again with a call for blind testing, an exercise that is of very limited value - if any at all - to the typical audiophile. I just don’t understand why those who call for such tests don’t conduct their own, and then share results with the group.

I’ve also suggested that the blind testing advocates organize such a test and recruit subjects from Audiogon. It could be interesting to have such a test session at an audio show, for example. (Caution! Results of such tests can be surprising - and even demoralizing!) When I’ve offered such suggestions in the past, I’m met with orders to do it myself, or required to put up money in a wager, or have an agreement with lawyers regarding the test.

To be clear, I think the results of these tests are not always what they seem, and I question the ability of these tests to correspond to what we actually experience as listeners and audiophiles. But they have their place.

Perhaps the problem is that it is not a simple matter to conduct such a scientifically valid, controlled double-blind listening test. And if it’s not properly conducted, a test obviously has no value at all.
