Anthem's MCA 325 power amplifier does well to complement the AVM 60 AV Processor. MCA 325 features more robust and efficient power and heavy-duty reliability. It delivers lower total harmonic distortion for more clean, pure sound and lower noise for a supremely quiet background.

Like all Anthem products, MCA 325 is like no other amplifier in the world: custom low noise high-power toroidal transformers high-current bipolar output transistors, high-quality filter capacitors, advanced power supply regulators, oversized aluminum heatsinks, custom-designed dual binding posts, and patented auto-on/off circuitry. Superior craftsmanship is reflected in clean, clear, audiophile-quality sound from top to bottom of the frequency spectrum.


  • Delivers lower THD for cleaner, pure sound and lower noise
  • Completely redesigned for improved audio performance and reliability
  • Higher current output for lower distortion
  • Cosmetic match for AVM 60 AV preamplifier-processor
  • Improved advanced load monitoring system
  • 8 bipolar output devices per channel for less stress on each device
  • Less than 2 watts standby power consumption
