I have to disagree with audiolabyrinth's post. The original Valhallas can definitely be bright on some systems but not Valhalla 2. I have Valhalla 2 power cords and speaker cables with YG Carmel 2 speakers (which can be very revealing as I'm sure you know) and the Valhalla 2 cables are rich, detailed and warm....the opposite of bright.
From a June 2016 Stereophile review of Valhalla 2 where Brian Damkroger compared the original to the version 2.
Use and Listening: First Things First
The first step in my review process was to hear how the Valhalla 2 References' sound quality compared with that of the original Valhallas, and to assess if, or how well, Nordost had met their design goals. This turned out to be very easy to do. First, there was no comparison between the two generations. The Valhalla 2s' performance was different enough from and so dramatically better than the original Valhallas' that, if not for the name printed on the cables, I would never have thought they were the same product line from the same company. It was also obvious that, in terms of meeting their goals, Nordost had hit a home run. My first impressions of the Valhalla 2 References, which remained unchanged throughout my listening, were of how smoothly the music flowed from note to note; of a very natural warmth and tonal richness of the sounds of instruments; and of how solid, dimensional, and tangible images and soundstages seemed. That's where my analysis would begin.
Have you made any decisions as far as cables go?
