Do you have a question about the Goldmund SR2.3 and is the answer not in the manual?
Optimum sound quality is reached after 15 minutes of power-on.
Reverting speaker cable polarity can increase sonic quality, requires experimentation.
Inverting AC plugs can improve sonic quality; experiment with speaker polarity.
