Can upgraded power cords help my setup?

Just because some can't hear a difference doesn't they don't work.  Try some to see if you can hear a difference.  I've tried things that didn't do a thing for me, but work great for others.  Just because it didn't work for me doesn't have me preaching it's snake oil.  

What about those of us experimenting and building our own? Are we defrauding ourselves?

The Analysis Plus Pro Power Oval goes for less than $100 bucks on line, one meter length and comes with Better than Hospital grade connector. $130 for 2 m length. Excellent value, no?

From Analyis Plus web site,

"Analysis Plus new PRO POWER OVAL uses better than hospital grade plugs that have a Perma-Lock Terminals, Large, high spring-rate contacts, Glass filled high temperature nylon front housing, Polycarbonate rear housing, Stainless hardware mated to a true balance cable for lower common mode noise. The 12 AWG gauge cable design has hot and cold leads that are symmetrical with a full shield around the hot and cold conductors to eliminate EMI/EMC. The cable also has the lowest inductance on the market for the lowest noise voltage of any pro power cord."
