POWER AMPLIFIER

Benchmark AHB2 – Power Amplifier

The AHB2 is a radically different audio amplifier. Its patented design delivers performance that approaches the limits of the latest high-resolution audio formats. Benchmark’s AHB2 power amplifier delivers musical details without introducing the masking effects of amplifier noise and distortion. The dynamic range of the AHB2 is 132 dB, making it 10 to 30 dB quieter than some of the very best reference-quality power amplifiers.

Unlike class-D amplifiers, the AHB2 is noise free over its ultra-wide 0.1 Hz to 200 kHz frequency range. Don’t settle for the limited performance of class-D amplification.

With the AHB2, you will discover previously overlooked nuances, dynamics, and detail in your favorite tracks. Experience the full potential of the very best high-resolution 24-bit PCM and 1-bit DSD recordings.
