Benchmark AHB2 Overview

The black AHB2 High-Resolution Power Amplifier from Benchmark is designed to accurately reproduce high resolution audio. The dynamic range approaches 130 dB, and the frequency response extends below 0.1 Hz and beyond 200 kHz. When reproducing high-resolution 24-bit PCM and 1-bit DSD digital audio formats, this amplifier allows you to hear nuances and dynamics which get lost when using amplifiers with lower dynamic ranges.

The AHB2 has bi-polar class-AB output stage that delivers high output current and low noise. The THX patented feed-forward error correction provides accurate cancellation of zero-crossing errors. In addition, the AHB2 uses a resonant switching power supply with a fast control loop so mechanical hum is eliminated while magnetic field strength is reduced.

The Benchmark AHB2 is the cleanest sounding amp I have owned across 35 years including amplifiers that cost 5X the AHB2. It only provides perfectly clean volume and nothing else. At this power output there is nothing that compares. B&H provided great service getting it to me safely.

Outstanding.

Perhaps the best solid state amp you can get for under $10,000? If not, within a hair of that.

Stunning power amp!!

I replaced from pioneer d amp by this AHB2. Both product is enough great for me. But AHB2 must be quite accurate amplifier. Uncolored clear sound/amplified , that's is my comment.

This model is known for its very low self noise and high signal to noise ratio using Benchmark's DAC3 digital to analog converter. It is also known for its ability to output at higher levels without introducing distortion into the signal.
