Hi all, I dont see a Valhalla rolling thread, so why not start one. I'm new to this Schiit brand, as I've only had a Valhalla for a week. I came from an MF XcanV3, that I liked very much. I'm not a FOTM sort of buyer, as I used the Xcan for the last 8 years. One of the things I needed in a new amp, was compatibility with my somewhat large pile of tubes. The Xcan used 6dj8's and I got a larger PSU so I could also roll in 6n1p types. The Val also will use these tubes. First thing I did when I received the Val, was to roll out the input tubes to a higher grade of tube, a 6n1p-eb. After a couple of hours, I could tell these were not to my liking. They were very forward, fast and a little cold. I tried a few others and finally found a sweet spot. So Schiit was not far off in there choice of the 6n1p. I found a higher grade in my pile, but not high enough to get a eb stamp. But man do they sound sweet and focused. They are a Rocket plant from 1971 with gold grids and rhodium plated pins.
