Anyone heard PS Audio Lab Cable?

I HAVE READ ABOUT THESE CABLES ON PSAUDIO.COM. THE DESCRIPTION THEY PROVIDE OF THIS CABLE IS INTERESTING. ONE THING IS FOR SURE IS THAT THEY ARE BIG. 6 GAUGE WIRE FOR ALL CONDUCTORS. THEY MAKE POWER CORDS FROM THE SAME CABLE AS THE LAB CABLE. THE PRICE IS RIGHT. BUT ARE THEY WORTH IT?
