Hearing is believing?........power cables.......

the problem is that liberal arts majors do NOT get a balanced education -- I know that quite well, having been close to the problem for some years

Lack of a basic science education leads to worse things than wasting money on placebo cables, anti-vaxers for example

kahlenz says: "I do not need a course in physics to buy a power cable.  There are plenty of choices available in all price ranges."

Of course there are.  As long as there are consumers who will pay more...believing that the more they pay the better their system will sound...the higher the price will go.  I mean, really, a power cord for $6000? Really? Really?

That power cable only exists because someone entepenuer knew if he built it fancy, packaged it well and marketed it to the easily swayed, he could sell enough to make a killing.  Good for him...the American way.

As someone said a long time ago: "Buyer beware!". But then you have to have a certain level of smarts to know to beware.

Perhaps you should consider that who you refer to as the "easily swayed" is more accurately yourself who is "easily swayed" by the notion that for some arbitrary reason of yours $6,000 is apparently too much to spend on a power cable. Perhaps those who buy the $6,000 power cables are not especially "easily swayed" at all, but are making a consumer choice with which they are comfortable whereas in your case it would be a purchase that would make you uncomfortable perhaps if only because such a consumer purchase would be beyond your budget.

The concept that there is something defective about those who might spend $6,000 on a power cable is actually a form of prejudice about someone you have obviously not met and whose budgetary and financial realities differ from yours to such an extent that you are unable to comprehend how they could possibly execute such a purchase and remain rational and yet at the same time you call them "easily swayed" so obviously you have a flaw in your "logic" here.

Moreover if we examine this "easily swayed" person who's behavior you conjure from your fertile imagination  you might ask yourself that if indeed this person is so "easily swayed" how is it that they have $6,000 to spend on a power cable rather than having already spent it on some other tomfoolery such as pricey cars or truckloads of Girl Scout cookies? After all they are so "easily swayed" how is it that the $6,000 power cable has so "easily swayed" their decision whereas other beckoning consumer products have failed to absorb their expendable $6,000?

This has been discussed previously.  That there are those with hefty "budgets" that don't know what they are doing.  They believe that everything (or many things) that have extreme price tags MUST be a better product.  They are wrong.  Some products sell at a high price because of the high price...at a lower price they might not sell as well.  I'd opine that the $6000 power cord is one of these products.

Since Value is the result of the mathematical equation of Quality divided by Price, such a power cord is a serious poor value regardless of whatever incremental SQ boost it might provide or how fat you boast your wallet to be.  High priced "exotic" items are rarely a good value and often exist merely because there are those that have no appreciation of that concept.

I'd also opine that the most successful people on the planet, who earned their own fortunes, do appreciate that concept and rarely waste money on poor values.
