6 - SOUND QUALITY OPTIMIZATION
- Warm-up sonic effect.
If the amplifier has been left unpowered for a few days, the optimum sound quality is
only reached after few minutes. The critical circuits have to warm up to 55
degrees Celsius (+131 degrees Fahrenheit) before achieving their optimal
performances.
- Speaker polarity.
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.
- AC line phase inversion.
The sonic quality of your SRI2 can be greatly improved if the main AC line is
connected with the proper polarity.
Try to invert the plug of your amplifier, using a special adapter.
We recommend that you proceed carefully to try this. You must do it in combination
with the speaker polarity to be sure of the result.
