Recently I switched positions of the components and used the Reference-II power cord for the amp instead of the Valhalla. I only took phono as a source so I could compare the power cords with exactly the same source, my turntable.
In several listening sessions I always preferred the sound of the Valhalla when used with the amp so it does not make sense to switch cables here. As I said, the Reference-II goes absolutely fantastic with the SACD CD player and I am very, very happy with it.
I will strongly recommend your product to other friends of mine although audiophiles to my experience are kind of dying species. There are not too much left in my neighborhood but you'll never know. Thanks again and all the best to you and your company.
