The second day with the iFi NOS 6922 on the MJ2, the LISSTs will stay in their box for now. Everything has more details, dimensions, and textures. Dynamics and extensions are also very good, no microphonics, not as hot as the stock tubes. Fuller deeper with a nice musical bounce that doesn't sound too tubey. For about 900HKD, these makes the Schiit MJ2 sounds a lot more interesting! Thank you Rowethren for suggesting!
The only concern now is how to unplug these without damaging them. The MJ2 doesn't allow to grab them from the base.
Glad you like them Regarding removal, the base is soldered on strongly so you should be able to just pull from the top after they have cooled down. They even supply gloves in the box so you don't mark the tubes which is nice.
