Power cord upgrade

Hey there 1971gto455ho, I'm hoping that my detailed response based on experience and with sources will supply other forum readers an option rather than spending serious coin on high end-high mark up power cables.  I cannot overstate how easy and satisfying it is to DIY.  Have a good week.

The debate as to whether power cords have an audible impact on the audio output of sound systems has been going on for years.  There is an excellent article written by Kurt Denke (Blue Jeans Cables)

on this subject in Audioholics dated April 29, 2011.  As far as the power cables that are in the middle to high end audio that equipment manufacturers use, I tend to trust their engineering.  By that I mean would they risk degrading the performance of their brand by opting to install a poor-quality cable to supply power to their equipment?  I know that my response does not answer your query, but as with many aspects of our hobby/passion power cord "upgrades" is a subjective one.  In the end purchase whatever satisfies your desires because life is short.

PS: to my previous response.  Have you considered assembling you own DIY audiophile A/C power cable(s)?  With very basic tools, (wire strippers, Phillips screwdriver, wire cutters. heat shrink tubing and a heat gun for setting the heat shrink (and a beer) you can produce top quality audiophile power cables.  Rather than spend several hundred dollars, or thousands if you are so inclined you can assemble DIY cables equivalent to that high dollar ready-made cable.  Here are some suggestions for raw cable from high quality "economy" cable to high end audiophile cable.

Economy -Coleman Cable Royal 12AWG 3Conductor SJOOO Power cable.  This cable runs $1.80 per foot from www.douglasconnection.com 

As to terminal ends the Wattgate5266i economy power plug connector at $16 is an excellent power plug for the 12AWG mentioned above.  For the source end I suggest the Wattgate 320i economy IEC power connector at $24.  The math indicates that an average 6-foot power cable would cost about $40.  That $40 investment would produce the equivalent of a $250/$300 off the shelf cable.  The next step up would be the Lapp OLFLRX190 CY Shielded 12AWG 3 conductor power cable at $10.40 per foot.  This is a German engineered product made in the USA.  Visit the Douglasconnection.com website above for more detail on any items mentioned here.  Oh, BTW I have no connection with Douglas i just like and use their products.  Finally, if you are Jones'n for that $2000/3000 power cable you can go with the Furutech FTP-3TS20 14AWG power cable at about $90 per meter (3.28 feet).  The 12AWG version of the cable is Furutech FP-TCS31 PC Triple C 12 AWG power cable at about $147 per meter (3.28 feet.  There is a selection of high end Furutech IEC and Power plug connectors that will facilitate nicely with 12 AMG cable.  If you choose diy power cables using any of the Coleman. Wattgate or Furutech products mentioned your efforts will produce power cables that will perform as good if not better that off the shelf cables costing 10 times more than the parts, you'd use to assemble you own.  And you have the satisfaction of doing it yourself not to mention you have saved bank that you can invest i other aspects of your audio rig.  You can do this. Enjoy!
