We have tested 91 power cords from $18000 down and I personally use the Core Power Technology cords that cost on average $700 per cord. I do however want to say that we are the Canadian distributor for this line and I am a dealer. My noise floor on my system dropped dramatically but resolution and dynamics increased. I no longer use any conditioning.
Cheers and just my 2 cents.
