SOUND QUALITY OPTIMIZATION
- Warm-up sonic effect.
If the power amplifier has been powered off for some time, the optimum sound
quality is only reached after several minutes. The critical circuits have to warm up
to 55 degrees Celsius (+131 degrees Fahrenheit). When the amplifier
has been used recently, the optimum is reached after only 10 to 15 minutes.
- Speaker polarity.
Even if you have a phase inverter on your preamplifier (as on the GOLDMUND
MIMESIS 2 or MIMESIS 22), 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 the speaker cable amp
termination. But since the line phase and the speaker polarity interfere to each
other, you have to experiment carefully all the combinations before picking the
right one.
If your preamp has an absolute phase inverter, this will interfere too. If it has not,
don't forget the result will depend of the source, most of the record and CD being
recorded without care for the absolute phase. Be patient…
- Main line phase inversion.
To select the proper phase, you have to select, by trying, one of the two power
cord positions, using a plug adapter.
We recommend that you proceed carefully to try this. You must do it in
combination with the speaker polarity and/or with absolute phase switching to be
sure of the result.
- The GOLDMUND exclusive "Mechanical grounding".
In the GOLDMUND MIMESIS 29M amplifier, GOLDMUND has, more than in any
other of its components, fully implemented an optimized vibration evacuation
path. This is called by GOLDMUND: "Mechanical Grounding".
