Hi Steve,
I think you misunderstood what we are asking.
From the Aphrodite spec sheet, it appears that the audio output is 3 v .
Likely RCA .
May be it is 6 V Balanced.
Now it seems that Lukasz want us to specify what prefer and have factory set the volume level???
We all have different audio systems. At this level I doubt any one be using a solid state op amp based preamplifiers.
Being able to operate one’s preamp with the volume control in a sweet range I think is important to a lot of us.
Some preamps sound better with 2 v input and some with 6 volts. It all depends on your system.
For example, the Spectral DMC 30 SV likes 6 volts.
When you switch to a Dagastino Relentless preamp, the 2 volt sounds best.
Then when you change to a Doshi or Conrad Johnson, the preferred DAC outputs be different.
Audio dealers won’t mess with that.or make any recommendations.
We just want to know as like you we all want the best configurations for the best sound.
Like changing to NOS tubes or uber expensive footers or power cords

If you spend 88’000 Euros for a car, I think you’ll be provided with more details on your purchase?
