If Power Cords Don't Matter...

First of all, I don’t own any high-end power cords, mostly because I can’t fit them behind my rack. Second, I am not trying to stir up controversy, as you will see from my question. I understand that the people who believe power cords make no difference argue that once the power gets into the component, the AC is converted to DC and the power supply of the component takes over completely. I think I have that right for the most part. So it that’s true, and it probably is from a traditional EE standpoint, why is it that I have not heard anyone say that power conditioners make no difference? I am not aware of anyone with a decent system ever saying that a Niagara or Triton or Audience teflon conditioner didn’t affect their sound, for good or for bad. So if the EE theory is true, wouldn’t power conditioners make no difference either? I have an Audience AR6T for almost 10 years and I think it made a big difference. BTW - I am not talking about Power Plants, which deal with voltage stabilization, which is a different topic.  Obviously, if your AC voltage is way off, it's going to cause problems.

To Millercarbon

Thanks for your response. I guess I missed the humor, sometimes I do. My handle is mispelled as I struggle with dyslexia. It is hard to type straight when I am tired. It talkes concentration, and where I can, on work or important things I always use spell check.

millerecarbon forgot to mention the regulator, which have improved over the years (to higher speeds, like Hynes, etc)

But it’s still not an ideal situation when the rectifier is ’forcing’ the inversion DC/AC. The line is already alternating w/ caps (only) getting charged at the peak & low of the wave. Never when rising/dropping, where it spends most of its time.

Then the the noise caused by this charging process. Then the power cord trapping noise in a component (blocking path to house-ground). The problems of AC-audio are hard to enumerate...

@troidelover1499 Maybe Tammy at Audiogon Support can help you with a name change to triodelover1499?

Sometimes when you think about all the challenges that are stacked up against them, it's little short of miraculous that audio components work at all.

Chayro’s , miller carbon’s and willy t’s comments are on point.  Expensive power conditioners and boutique power cords will make no difference in the characteristics of the DC current delivered to the amplification devices (tubes or transistors) which is produced by the amplifiers power supply, which incorporates, usually, “filter,” capacitors.  I suspect that some of the anecdotes in posts, above, claiming improvement in SQ from such tweaks are really just descriptions of placebo effects.
