![]() Immediately after placing it in my headphone setup, all other amps felt muddy, raw, unpolished or slow sounding. You can see it everywhere around here, it was put in at least ~40 reviews as all my headphones, DACs and power amp reviews were made with its help. I was given the privilege of reviewing the world-class Benchmark HPA4 preamp and headphone amp some time ago, that in time became my daily driver work horse. This strong philosophy behind their products is surely not for everybody…but if you care for honesty and absolute transparency, then all Benchmarks products will be providing you exactly that. When you see the Benchmark logo on an audio component, you can be sure that it was designed to be acoustically transparent and as neutral as possible, without inducing coloration or deviations from linearity. I had at my disposal three Benchmark products and years later, they still looked as good as when I’ve received them. Besides being passionate for all things audio, they’re also serious about durability and build quality of their products. Luckily, Benchmark’s crew isn’t formed only by nerdy engineers, as you’ll find musicians, audiophiles and audio professionals throughout their ranks that don’t care only for the numbers (measurements), but for the end result as well, as no matter how good or bad a component is looking on a screen, the final verdict is still delivered by our hearing apparatuses. Besides bestowing world-class specifications, everything they make is backed-up by measurements produced by the world’s best audio analyzers. THE QUIETEST, CLEANEST AUDIO AMPLIFIER ON THE PLANETįrom the first watt to the last watt, no audio power amplifier offers lower noise or lower distortion than the Benchmark AHB2.Benchmark Media doesn’t need an introduction whatsoever, as their name implies - they’re committed to excellence. The result is an amplifier that stands head and shoulders above the competition. 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(TM) 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. INTRODUCING THE AHB2 - A NEW AND DIFFERENT POWER AMPLIFIER Benchmark set out to solve this problem by creating an amplifier that matches the performance of the DAC2. Until now, this meant that the DAC2 could not be fully appreciated. For example, the noise and distortion produced by the Benchmark DAC2 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 to the performance limits of High-Resolution-Audio (HRA) formats. Black or Silver, both are currently in stock now!!
