Yamaha A-S501 vs Marantz PM6006

Marantz PM6006 vs Yamaha A-S501

Marantz PM6006 review

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. Marantz PM6006

Yamaha A-S501 review

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. Yamaha A-S501

Marantz PM6006 pros & cons

Pros

  • Marantz has a fundamental understanding of what looks good, especially when you stack a PM6006 on it and make your other friends jealous
  • iDevice Management

Cons

  • I've had issues with volume control because the remote is too sensitive and makes it difficult to fine-tune the volume

Yamaha A-S501 pros & cons

Pros

  • There's a mode where you can even bypass the filters and switches for even higher fidelity sound
  • It can drive 4 ohm speakers without destroying the amp, which is pretty impressive
  • There's actually a switch in the back for that with a 4 ohm label, so you know it's not just hype

Cons

  • If the unit was turned off, a relay would randomly click inside, sometimes within minutes or even seconds
