And if the Linlais are gonna score really well, may just get quad Linlais for my Freya + like you have done. Schiit apparently recommends all quads being of the same tube make. So may go down that road.
@ram18 , a quad of Linlai's may provide more clarity and weight. I'm going to try them in my both my preamp and amp. The reason I recommended the GTBs over other Sylvanias was to take the edge off your speakers and for their deep imaging. Most Sylvania have extended and detailed highs.
