I have Valhalla 2 cables, cords, and interconnects throughout my system and my take is that they are a transparent pass through of your front end and they just go away and let your system sing...I love them.
I'm randomly demoing a Crystal Cable Van Gogh interconnect and don't hear much of a difference between the Valhalla 2 and this $22.5K interconnect...not sure if this would be different if my entire system was CC Van Gogh.
