Sound Quality Optimization

❑Warm-up sonic effect

If the power amplifier has not been powered on for a few days, the optimum sound quality is reached after 15 minutes. This delay has been optimized to be minimal and the sonic quality when just powered on is much higher than other quality power amplifiers.

❑Speaker polarity

Even if you have an absolute phase inverter on your preamplifier (Mimesis 22M), and even if you have carefully selected the proper line phase (see in next paragraph), there is a possibility to again increase the sonic quality of your speakers by reverting the polarity of each speaker cable at amp termination. But since the line phase and the speaker polarity interfere to each other, you have to experiment carefully with all the combinations before picking the right one.

If your preamplifier has an absolute phase inverter, this will interfere too. If it has not, don't forget the result will depend on the source, as most records and CDs have been recorded without care for the absolute phase. Be patient…

❑Mains line phase inversion

The sonic quality of your GOLDMUND SR150 can be greatly improved if the mains AC line is properly connected. Try to invert the AC plugs of both your amplifiers, using special adapters.

We recommend that you try this carefully. You must do it in combination with the speaker polarity and/or with absolute phase switching to be sure of the best result.
