You had posed this question sometimes back or on another forum - that is the gain that Accuphase owners use in their system. Per my preliminary experience, I find that setting the gain to -12db on the amplifiers provides me a well balanced sound. This is based on the face that I can now set my DAC as a LINE source instead of using it as a VARIABLE volume control. This way I get the desired levels with the volume on the preamp between 11 o'clock and 1 o'clock position. I reach between 1 o'clock and 2 o'clock positions for SACDs or HDCDs. I believe the DR on these must be high? But on CDs and Spotify, I am good by 11:30 position.
What did you end up with?
