Curious. Kimber Palladian Power Cord.

It's a standing wave guide. Does that help? Take the price up what 700-$800 from the models with out the "thing". You don't want waves standing around, come on, you're that smart.

Seriously, I don't know, but I have one of these, and I've also own a Fim Gold, transparent ref xl, shunyata python and I love it. Everything sounds more dynamic, more detailed, blacker backgrounds...but doesn't change the tone of the music.

Go for it. I started with one and now have four.

It feels like a cylinder of concrete, but whatever it is, there is no question it makes a substantial difference.
