Benchmark ahb2 power amplifier for sale12/7/2023 ![]() The AHB2 Reference power amplifier has a reported 132-dB signal-to-noise ratio. Low noise and distortion are in the company's DNA and are the ultimate goals with every product produced. In my recent review of the DAC3, I discussed Benchmark's philosophy to pursue musical sonic transparency. Knowing the company's reputation and having owned its products in the past, I was definitely intrigued. Benchmark clearly states that the AHB2 represents a "radical approach" to power amplification. ![]() Terms like low-bias, Class H, Class G, and feed-forward error correction are not terms that accompany the workhorse amplifiers I usually live with. So, when Benchmark shipped me the AHB2 Reference Power Amplifier (100 watts per channel into eight ohms, 380 watts bridged mono into eight ohms) along with the new DAC3 preamplifier/DAC that I already reviewed, and I first read the manual-yes, I read manuals-I was initially taken aback. Nonetheless, these amplifiers are my references, matching like peas and carrots with my Focal Sopra N☁ speakers. Their downside is that they are inefficient and dissipate a lot of heat as they consume a lot of power. These amplifiers are deep-biasing, always ready to handle musical transients and dramatically shifting dynamics. When it comes to amplification, I am admittedly a Class A guy, and I love the two Class A amplifiers I currently own: the 30-watt Pass Labs XA30.8 stereo amp and the 10-watt First Watt SIT-2 stereo amp. Some embrace gear based just on sound quality others embrace gear on sound quality along with design philosophy.

The result is an amplifier that stands head and shoulders above the competition.Ī rackmount kit is also available. In our quest, we also focused on frequency response, output noise, drive current, damping factor, and reliability. No other audio amplifier comes close to delivering the clean, quiet, and robust power of the AHB2. ![]() This technology uses feed-forward error correction to eliminate the distortion that is normally produced by the output stage. The AHB2 uses the new and revolutionary THX-patented AAA™ technology to virtually eliminate all forms of distortion. This was exactly the technology we needed to build our new amplifier. In our search, we learned of two new patents on a new amplifier technology from THX. We had to look beyond existing amplifier technologies and explore some new and radical solutions. Benchmark set out to solve this problem by creating an amplifier that matches the performance of the DAC3. Until now, this meant that the DAC3 could not be fully appreciated. ![]() For example, the noise and distortion produced by the Benchmark DAC3 D/A converter is 20 to 30 dB lower than that produced by most high-quality power amplifiers. This means that the power amplifier has become a limiting factor in many audio systems. In contrast, the revolutionary AHB2 was specifically designed to deliver true high-resolution performance.ĭ/A conversion technology has outpaced the development of new power amplifiers. Most power amplifiers are well matched to the limitations of the CD format, but they fall well short of the capabilities of high-resolution formats. Power amplifiers are a weak link in most audio systems. The musical details and emotion captured on today's finest High-Resolution-Audio recordings can only be fully appreciated when every component in the signal chain is capable of true high-resolution performance. With the AHB2, 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 frequency response of the AHB2 extends beyond 200 kHz. 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. Benchmark's AHB2 power amplifier delivers musical details without introducing the masking effects of amplifier noise and distortion. The AHB2 is the ideal match for the performance limits of High-Resolution-Audio (HRA) formats. Benchmark has raised the bar by introducing a new and revolutionary amplifier! The Benchmark AHB2 Power Amplifier is the quietest and cleanest sounding power amp ever! From the first watt to the last watt, no audio power amplifier offers lower noise or lower distortion than the AHB2. Schroeder Amplification is proud to be an authorized Benchmark dealer and user! This Benchmark AHB2 Power Amplifier is brand new and includes its full manufacturer’s warranty.
