To all you who have the ANK Dac 2.1 Level B! I have the Level B Signature yet I wanted to improve the sound so I decided to go with the 12AU7.
I had the design and work done by Archie ( http://www.thediscerningear.com/, the ANK premier dealer. He made the changes which had to be done,(12 Volt Tap, different values, etc.)This change makes the Dac sound warmer and more musical.
I went with his Power supply board upgrades, Dac Board changes, etc. and now my Dac sounds so good it is like a great Vinyl Turn table with better dynamics.
I no longer desire to go to the 3.1 because the sound is no wonderful I am loving the analog sound.
