Accuphase dac 60

Since Accuphase apparently designs their devices for the same voltage whether balanced or unbalanced, you might try the unbalanced output from the PS Audio DAC for closer comparison. 

Are the optical and coaxial digital inputs two different sources?

Also, how is your Sub connected?

I see that the “preamp section output voltage “ is 1.23v. Since the DAC 60 is placed into this circuit I’m don’t know if it just utilizes this for voltage gain. If so 1.23is pretty low. Speculation for certain.

The unanswered question is does the Accuphase DAC 60 card have an independent output voltage or is it totally reliant on the preamplifier output voltage of the integrated amplifier?

yes, two different sources for optical and coaxial. The Rel T7x is connected with there speakon high level connection. Great sub by the way, I need to add another one.

I am guessing it is on the preamp. I can’t find anything on it and they are just inputs. How do most higher end companies do it, like luxman, rotel michi, Anthem, Parasound or anyone that has a built in dac on their preamp? I don’t know.
