Technical and scientific discussion of amps, cables and other topics.

Some Observations

First of all, audio cable sonics are a subtle thing, and can usually be discerned on a familiar system with enough resolving power.

However, you were no longer listening on a familiar system, your room had changed.

You used a less resolving signal source, the Pioneer, and then proceeded to load the Pioneer output with TWO cables at the same time. This would cause the sound of a "better" cable to be corrupted with the inferior performance of the lesser cables insulation, as they would be in parallel with one another. About half the total overall 'sound' of a cable is in it's insulation material, so this paralleled cable situation eliminated at least half of what would make a cable sound different/better than the other.

Add to this a quite probably questionable listening method, and it is no wonder that no sonic differences were heard, you only forgot to stuff cotton balls in your ears for the final step.

You seem overly concerned with placebo effects, but fail to realize that bias can work both ways as well, and cause one who has (for whatever reason) become 'convinced' (or even doubtful) that there are no diferences to be heard, to fail to hear differences that are actually there.

A failed listening test is nothing more than that, it is not proof of any kind that there there are no sonic differences.
