Mikelavigne, I have the Audio Note DAC 1.2, which is not an upper level AN DAC, however it has all Black Gate caps, tantalum resistors, solid silver wiring, a custom (internal) HMS Gran Finale IC, AN copper caps on the analogue board, NOS tubes and AN DAC 4 silver wire interface transformers. It has been taken to about as high a level as I am capable of taking it. I don't know how it would compare to the other AN DACs or the Meitner DAC, but since I recently added the AN DAC 4 interface transformers, it now seems phenomenally good.
Have you had any experience with the Audio Note DACs as compared to the Meitner?
