Primaluna Dialogue One with NOS Russian Reflector 6n3ce; NOS Amperex Bugle Boy 12au7; NOS Sylvania 5751 black plates.
keep in mind that the vintage of the tube is factor in determining its sound.

with 12au7, i find the older brimar and mullard are my favorite. so far a tungsol 12axz has worked well in my cd player, but i am not sure of its vintage.
