The AHB2 boasts a dynamic range of 132 dB, making it 10 to 30 dB quieter than almost all high-end reference quality amplifiers. Musical details are delivered without the obscuring effects of noise and distortion that many amps naturally exhibit.

To 200 kHz And Beyond

AHB2's frequency response extends beyond an amazing 200 kHz, revealing even the finest nuances, dynamics and detail in recorded material.

Many power amplifiers are matched to the limitation of CD format performance and as such fall short of the capabilities of high-resolution modern standards. Benchmark's AHB2 is specially designed to deliver true high-res performance and harness the full potential of formats such as 24-bit PCM and 1-bit DSD.

In A Class Of Its Own
Benchmark AHB2's internal circuitry layout

Under the hood, the AHB2 also takes advantage of THX's proprietary AAA technology to virtually eradicate all forms of distortion and noise. By using a technique THX call 'feed-forward error correction', the circuit is able to eliminate all distorted artefacts usually found at the amplifier's output stage.

Delivering huge doses of clean, quiet and robust power, the AHB2 raises the bar for all reference quality power amplifiers even at the top of the market.
