The extended frequency response delivers a nearly perfect impulse response, and a nearly perfect phase response. At the other end of the audio spectrum, the low-frequency response extends below 0.1 Hz. The frequency response of the AHB2 extends beyond 200 kHz, to deliver the ultrasonic detail and fast transients captured by high-resolution recordings. The AHB2 is a the ideal match to the performance limits of high-resolution formats. The AHB2 delivers a noise performance and a frequency response that is well matched to the capabilities of DSD and 24-bit PCM formats.
#BENCHMARK AHB2 POWER AMP FULL#
You will discover previously overlooked nuances, dynamics, and detail in your favorite recordings and experience the full potential of the latest high-resolution 24-bit PCM and 1-bit DSD audio formats. The dynamic range of the AHB2 is 130 dB, making it 10 to 30 dB quieter than the typical reference-quality power amplifier. Benchmark's AHB2 power amplifier delivers musical details without introducing the masking effects of amplifier noise and distortion. High-Resolution audio is only as good as the weakest link in the playback system. Benchmark's goal was to build a power amplifier that could deliver the full performance of their flagship DAC2 converters, and today's finest high-resolution recordings. In most audio systems, the details captured by today's high-resolution 24-bit PCM systems are lost in a veil of amplifier noise and distortion. The differences between 16-bit and 24-bit recordings are inaudible when the power amplifier can only deliver 16-bit noise performance. Most power amplifiers cannot deliver the resolution provided by these converters and limit system noise performance to the equivalent of a 16 to 18-bit digital system. Benchmark DAC2 D/A converters outperform most high-end power amplifiers by very significant margins. High-resolution recording formats and converter technology have outpaced the development of improved power amplifiers. Power amplifiers are usually a weak link in the audio chain. – John Gatski, Everything Audio Network A New Benchmark "The Benchmark brings out nuances of reverb, quick percussive guitar attack with amazing clarity, but no over the top edginess.The -130 dB noise/dynamic range just gets us that much closer to the live music signature that we yearn to hear from our beloved electronics." "I very much enjoyed my time evaluating the Benchmark AHB2 amplifier and can heartily recommend it to those seeking one of the lowest distortion and lowest noise amplifiers on the planet – one that is very musically transparent and easy on the ears to boot." "As desired in a studio setting, the sonics from the AHB2 are neutral, and in my home setup, there is no observable emphasis in any particular frequency range." While costing only $2,995, it is hard to imagine asking for much more in a power amplifier." It is a technologically advanced and remarkable amplifier that can hang with any amp in its class because it is sonically transparent, images beautifully, and produces authoritative bass. "The Benchmark AHB2 embodies everything that a solid-state amp should. – SoundStage! Hi-Fi, Recommended Reference Component
"If ever there were a giant-killer of an amp, this is it." – John Atkinson, Stereophile, Class A Recommended Component "This is an amplifier with very serious slam, and – even better for those with less sensitive speakers, big rooms or just a hankering for 'just in front of the PA stack' listening levels – it keeps it all together however loud you decide to play things." – Paul Seydor, The Absolute Sound, 2019 Golden Ear Award I can't recall why I didn't purchase the loaner when I reviewed, but that has since been rectified: The AHB2 is now my reference amplifier."
"There's nothing here to inspire cults, 'merely' a precision instrument that performs the precisely defined task of reproducing music and sound essentially to perfection. With AHB2, you'll finally hear what you've been missing in high-resolution playback. Significantly quieter than typical reference amps, the Stereophile Editors' Choice Award-winning and Class A Recommended AHB2 touts extremely extended frequency response at both spectrums, patented error-correction technology, remarkable efficiency, a bi-polar Class AB output stage, and an innovative power supply. Given Benchmark's sterling reputation with digital audio, it's not surprising the company has built a groundbreaking power amplifier, AHB2, capable of delivering the full performance of its flagship converters and the world's finest high-resolution recordings.
