My experience has been the same as Bo's. Valhalla has great resolution and top end. But you might find more weight, depth with other cables. In my experience they worked very well on my preamps, but I felt that the thinned out my digital front end too much, some more than others. Odin might be the ticket, but I have never tried them.
Nordost Valhalla Power Cords
.....a question directed to the owners as well as the past owners of these power cords. We do not need to get in - what will it be going on, what are the room dimensions, what music do you listen to etc, etc, etc. Just your thoughts on these power cords...as I have mine and just want to see / hear what you think.
