Question for Atma-sphere, will expensive power cables improve your amplifiers?

The reason I am asking is I feel manufacturers of high quality components include all that is ever needed, power cable wise. Sure, some people buy power cables because they need special lengths or have some out of the ordinary "noise" issues that need extra insulation. Some even like the visual aspect of the aftermarket cables. I’m just curious why many spend thousands of dollars on such when the manufacturer has taken the power cable into account when producing the product. I cannot see a High-quality audiophile component maker (especially some that sell volume) pass on a few dollars for a better sounding power cable if indeed the cable improved their product. I cannot see a person buying that $7000 amp is not going to balk if the product was introduced at  $7100 (with the better cable). 

I wonder if Luxman, Accuphase, McIntosh, Gryphon...you name it "dressed" their power cables up to look like expensive aftermarket cables, owners would be so quick to "upgrade"?

I’d be curious to hear Ralph’s opinion on the subject

Because the customer has to be able to plug it in right away. Even though they may never use the stock cord, if you were a manufacturer and didn't include it you'd hear about it right away.

Then why don’t amplifier manufactures include speaker cables?  An amp is used to drive a speaker…..correct?   Obviously, I’m being sarcastic.

While rumor often has it that Pass doesn’t believe in upgrade power cords and cables, rumor and visitors also report that Pass uses expensive Silent Source Cables in their listening room and at shows...my Pass mono blocks came with good power cords, but I prefer my Cerious cords...

@oberoniaomnia, aren’t both cables in the photos above DC power from the power supply to the receiving equipment. Wouldn’t that be comparing apples to oranges.

@jea48

The cables shown in the pics carry DC power, but how is DC vs AC apples to oranges as far as the quality of the cables is concerned?

(If I misunderstood something I apologize)

The rectified DC is filtered through electrolytic caps to smooth out the full wave DC ripples and then in many cases is run through DC regulators.

The AC power cord plugs into a wall outlet. Hard tell what its about to receive. The good, the bad, and the ugly...

One question, do you mean voltage drops from the "wall" or within the amplifier itself due to volume adjustment.

@aberyclark I’m referring to Voltage drops from the wall. In the case of our class D the volume control will affect the Voltage drop.

Usually the house wiring has far less Voltage drop than the power cord. This has a lot to do with the fact that wiring in the wall is solid core. Such wire is not legal for power cords. So if anyone is wondering about the ’last 6 feet’ that’s the answer.
