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.  
@jafant = Me? The thread got quite off topic, but that happens.  I was asking why I don't hear an outcry from people who say power cords don't matter also saying power conditioners don't matter.  If AC is AC, nothing in between the wall and the component should matter, absent something that does not allow the current to pass freely. We hear people all the time say power cords are BS, but usually not that power conditioners are BS. 
So that's it.  We're on to the next thing, whatever that is. 
Millercarbon.  How did you terminate the 4ga wire on the load side of the circuit??
4 ga is stranded wire. Snip off strands until what is left will fit, and tighten down.
