Most Beneficial Cable Upgrade

AC power cords and most other power "conditioner" products. The sales claims sound logical: Noise and static can get into your gear through the power line and damage the sound. In severe cases it's possible for power-related clicks and buzzes to get into your system, but those are easily noticed. The suggestion that subtle changes in "clarity and presence" can occur is plain fraud. Indeed, every competent circuit designer knows how to filter out power line noise, and such protection is routinely added to all commercial audio products. Spending hundreds of dollars on a six-foot replacement power cord ignores the other hundred-odd feet of regular wire between the wall outlet and power pole.The real answer is? Use logic and really listen with someone else but you doing the switching and you might just see the silliness of it all.

You know, the job of a power supply is to convert the AC to DC, and filter out whatever kind of noise might be prone to occurring on any of its outputs, including ground.

If a power supply successfully does this, there is no need for any power cord beyond that which can convey enough power.

If a power cord TRULY DOES MAKE A DIFFERENCE, there's something wrong with the power supply its attached to.

Matjet: thanks for the kind words.Here is a price list of what usually goes into most very high priced esoteric power cords..I wish they really did work magic. But alas only in fairy tales.

1. 1 Schurter 10 amp IEC - $5
2. 1 Hubbell 15a 3 prong plug - $5
3. 6 feet of Black, Green and White 14g THHN 600v Building Wire - ~$0.30 /foot = $1.80
4. 6 feet of clear braided garden hose - ~$0.50/foot = $3
5. ~1 pound of ferrous metal powder - can't find a price, I'm sure it's dirt cheap
6. a stick of hot glue - the Hubbell connector had a hole drilled in it and was filled with hot glue, the female end was just glued to the hose.
7. Approx. 6 inches of electrical tape
8. Large size heatshrink
9. Techflex

now does this look like high end science to any of you...lol
