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

If every wired audio component forms a "link in a chain", how can replacing just one "link" in the chain have an appreciable effect on the whole chain?

Is the goal of substituting one less-effective link with a more-effective link to improve the conducted "signal" from the improved link onward, and how does that work?

(i believe atmasphere partially answered that question above, but I'm perhaps too dense to comprehend the explanation)

I agree the cable companies "loan" the cables...but if Pass thought their own cords sounded better, can’t imagine not using them in their voicing room and at shows...I read where Nelson Pass was loaned a pair of Kimber speakers cables, and quite liked them, until he learned they were $54.000 a pair...in their older manuals Pass simply said your cables shouldn’t cost more than your components...it's a fun company...

I have MA-1s and noticed some improvement with aftermarket power cords. Very expensive and borrowed. Didnt like the high end Shunyata power conditioner on these amps so they go right into my wall.

Power cords are (mostly) three runs of stranded copper wire with PVC insulation, twisted together (sometimes with filler material for damping), and encased in a PVC jacket.  The main variables that affect power transmission are the wire gauge, shielding (or not), and connectors.  It is not that expensive for an equipment manufacturer to include a sufficiently sized and shielded power cable that will facilitate pretty much the full performance level of their equipment.  That should be the baseline.

"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." 

Wouldn't that be a case for keeping component power cords as short as possible?
