The power of the amp is 40W per channel at 8 ohms. At the same time Yamaha has 85W (8 Ohms). The model uses current feedback, which helps to minimize distortion, expand the frequency range, obtain excellent transient characteristics and, in combination with a powerful PSU, ensure reliable operation even with capricious speakers in terms of impedance. The preliminary and final stages of this unit are assembled on discrete elements, and there are no microcircuits on the signal path.
The amplifier model was designed in accordance with the principle of ToP-ART (Total Purity Audio Reproduction Technology). Thus, the circuitry of the right and left channels completely repeat one another. A-S501 has a special anti-resonance base ART Base, as well as an additional massive jumper in the center of the case, which reduces possible vibrations. It should also be noted that the A-S501 volume control moves extremely smoothly and does not cut the frequencies even at the lowest volume.
