I just received my Freya on 7/22, unfortunately, one 6N8S has a dead triode, I substituted a short RCA 6SN7 for it in one of the cathode follower positions, turned it on and started listening Even though it has not burned in, I found the Freya to be quiet, expansive it it's soundstage, and not adding any coloration. The controls are easy to use, and the remote is fine for its intended application. I emailed Schiit for a replacement 6N8S, and found that I have a number of 6SN7 and 6SL7 tubes to try, including 2-6SL7 brand new in the box, accepted by the government in January 1952. I intend to start with the stock tubes, but have a lot of options. Any thoughts?
