Design philosophy and description


Blue Moon power amplifiers follow the path of Class D that we consider the amplification technology of the future. This is why today a great power and compact dimensions are required to drive loudspeakers.

We have chosen modules with a power supply similar to the analog one, using a larger area of the sine wave  instead of one single narrow spike obtaining remarkable sound results.

Exploiting only a small portion of the big typical power indicated is another key point to reach considerable effects. By doing this, just a little distortion and a high level of musicality are assured as well.

In conclusion, internal cables have been treated with special care, using very high quality products even in the power section. All of them have been insulated and shielded to avoid contamination from the electromagnetic fields into the cabinet.


Mains filters and the external parts of the amplifier module have been insulated as well.

Assembly and cables are entirely handmade to pay the utmost attention to connections.

Bakelite has been used for the rear panel: it is a material at a very high electrical insulation, big damping and extreme neutrality helping to reach the best sound results.
