Let's talk power cords

Are there any blind studies on this issue??  You can find glowing reports from people claiming magnets on their wrists cured their arthritis. Such reports are as convincing as the reports here from listeners that such cords have an impact on their system. I have YG Anat 3s, Chord Electronics and a DSX processor and I have never been compelled to buy such aftermarket cords because the science is snake oil. Sorry guys your ears are easily fooled. 
Show me some research that is compelling that such power cord could and does make a difference both in the function of the downstream electronics and more importantly that when listeners have no idea what cord is being used and all other variables are controlled they can hear the difference. Until then this is snake oil. I want to be convinced.

with gear that good I would think you would want to do your own double blind test with your own system. that's what I did...it was actually fun and didn't take very long, and improved my system for minimal cost...

Try listening to your system without power cords and see if they matter.  Yes they play a critical role otherwise we would not need them. Try using a lamp cord to power your your bulky monoblock amps and see how that goes for your ears and system.  

We all agree power cords play a vital role. It seems rather narrow minded and unreasonable to NOT think construction methods such as shielding, conductor material, braiding configurations, dialetrics etc... play a role on this vital part of our audio system. 

They are in the signal chain folks. If you think not, then just remove them and enjoy your music. 

randy-11,
The change in sound quality is unquestionable. 

They absolutely make a difference.  As does cabling in general...as well as room acoustics / system synergy ETC.  Best thing for you to do is to try some...and make your own judgements.
