Any expericience with Nordost Valhalla powercord ?

Dear fellow-audiophiles,
Do any of you have something to say about the use of the Nordost Valhalla powercord on cd-players ?
What are your comments about this powercable ?
Is it as good as the reviewers and the audio magazines tells us ?
I'm considering to buy one, but want to hear other users comments. I use already Nordost Vishnu powercables in my system, but like to bring it at new levels with the purchase of one Valhalla.
My system : Bow Technologies ZZ Eight cd-player, Bow Tech. ZZ One Ref. amp., Totem Mani Two speakers, Nirvana SX interconnect and Nordost Vishnu powercables.
Thanks a lot for your words,
Happy listening !
