Upgrading power cord.. proven upgrade? or crap?

Too much has been said on this topic already, but...

"Those who believe in the benifits are those who have tried. Those who say it can't don't know."

I've read countless articals on wires, cables, Opp amps all trying to explain something one hears but is not able to measure. If you can not measure it with todays technology that only means it has not been measured, not that it didn't effect the sound. The audio community has a tough road in that alot of what we hear is symply not explained with our 1950's measuring techniques. If you want to do yourself a favor, try everything, keep what you like and stop trying to explain beyond "it works". If you need an explanation than your not hear to find the best quality sound reproduction, you may want to try a scientific site!

My experience is that all cables make a difference, sometimes good, sometimes bad. I have found the old rule of 10% of the system budget is far short of a correct number. For me it's been 50% plus befor the benifits are outweighed by the cost. In audio I think we must remain open to the possabilities if we want the very best from our investment.

J.D.

Yes indeed power cords do make a difference, maybe some folks systems are not high enough resolution to pull the extra detail out of the upgrade. The question is, are they a good value? Most major power cords have less then $100 of materials in them the rest is all marketing, and these cables go for a few thousand dollars! that is crazy! Buy one take it apart and build a few clones and then sell the original, you’ll get the same improvement but will have 1/10 the cost into it. Not for everyone but I know more then a few folks who have had great luck with such upgrades, besides it keeps the WAF low, I think there is an additional 10% surcharge on the WAF when crazy high buck cables are purchased

If you cannot hear an IMMEDIATE improvement on ANY component with a LessLoss PC, then you should have your hearing checked or find a different hobby.

NOTE: There are exceptions for some digital pieces with certain power supplies that could care less what kind of power cord you put in - like my buddy's Wadia CD player (now sold)... we tried back and forth with a $10 stock PC and a $1,200 LessLoss PC - no difference AT ALL.

I wasn't a believer until I had a Argento Flow Master Reference connected to my Sanders Magtech amp.  It definitely was better than my Groneberg power cable.
