Commentary
A power amplifier developed with the technology of the pre-main amplifier A-10 series.
The A-10XXP comes in three variations : "Type I" with balanced input and no volume, "Type II" with volume with mono (balanced input) and stereo switching, and "Type III" with balanced / unbalanced input and no volume.
The power supply circuit is equipped with a reserve power supply, which was developed to achieve near-perfect tracking performance for dynamic and discontinuous music signals. The power supply circuit is also equipped with a large transformer and large-capacity capacitor to provide a low-load power supply.
The transformer, filter, capacitor and voltage amplification stages are all constructed using twin monaural construction. In addition, the monocoque structure with reduced natural vibration is used to achieve high-quality playback sound.
11 kg natural granite is adopted for the top plate in order to bring the ideal of direct mechanical ground construction which drops the vibration to the ground with the heavyweight leg closer to the perfect one.
All parts used are of the highest grade to achieve a high quality sound.
Real wood is used for the front panel and side panel.
In addition, the top plate, front panel, and side panel can be combined from several kinds of wood.
