The Benchmark AHB2 Power Amplifier is known for its exceptional performance and is considered one of the quietest and cleanest audio amplifiers available.

Benchmark AHB2 Power Amplifier, Black Key Features

  • True High-Resolution Performance - The AHB2 is designed to match the performance limits of High-Resolution Audio (HRA) formats. It delivers musical details without introducing amplifier noise and distortion. The dynamic range of the AHB2 is 132 dB, making it significantly quieter than many reference-quality power amplifiers.
  • Frequency Response - The AHB2 has a frequency response that extends beyond 200 kHz, allowing you to experience previously overlooked nuances, dynamics, and details in your favorite recordings.
  • THX-patented AAA Technology - The AHB2 utilizes THX's patented AAA technology, which employs feed-forward error correction to virtually eliminate distortion produced by the output stage. This technology sets the AHB2 apart from other audio amplifiers and delivers clean, quiet, and robust power.
