Thank you, solderdude. So, when we ignore the amp for a moment, would it be fair to say that on the source side (ADI2) there should not be a relevant degregation of the signal quality when reducing the analogue levels largely (i.e. -50 or even -60db with more sensitive headphones)? Isn`t there a point when the difference between the actual signal and the noise floor is becoming to small? Again, sorry if these are stupid question... Just trying to understand how this all relates.
