Do powercords make a difference in sound?

Douglas_schroeder, were this a science there are many factors that would have to be held constant, such as time of day, as electricity demand varies, holding all other things constant, choice of music, etc. But it is not a science; it is a consumer's decision about purchases. If Liguy is satisfied, that is it.

With fewer and fewer dealers and with the proliferation of electronics and speaker manufacturing, even were there many dealers, ones opportunities to listen to comparisons are most limited. Reviews also are of most limited use, as few will have much knowledge of all the elements leading to the reviewer's judgment. A circle of friends whose ears you trust are most vital.

So you do not see anything objectionable about promulgating a conclusion about biwiring to the rest of the world, via an Internet forum, based on a comparison in two completely different rooms between two systems that were completely different aside from the speakers?

Whether or not the poster was satisfied is irrelevant. The issue is that others may be induced to direct their investments of time and money based on conclusions that were reached via methodology that is fundamentally flawed.

Almarg, I don't think anyone expects you to critique their decisions on wine, women, or song. Frankly, I don't really trust anyones experiences, other than a few friends where my experiences and theirs have corresponded frequently.

Also, I am very distrustful of those who use phrases, such as the laws of physics, etc. If I hear something very striking, as I know that our knowledge is incomplete, I ignore such opinions.

As a retired scientist, I have done my duty to the scientific method in noting research that violates ceteris paribus. I do see no reason for your avoiding pointing this out, however, as long as you know it may be ignored.

I agree there are infinite number of dynamic variables but you should minimize as many as possible in an experiment. In this case, one obvious is performing the test in the same system. I can't believe you are arguing this point.

But it is not a science; it is a consumer's decision about purchases. If Liguy is satisfied, that is it.

Purchasing decision is not science but the test that lead to the decision IS ... logic, common sense ...

Tbg: So very well stated, sir. I echo your comments. I am amazed at how complicated some guys make this process. I've been marveling at that AC outlet experiment thread going on, for example. This is such a simple issue....get an appropriate audiophile AC cable, swap it out for what you have and listen for the result. Nothing else is required. You like what you hear or you don't....done.
