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. and thank you for the comparisons of the Halo A21+ with the Benchmark AHB2, as I am in the market for a power amp directly in this price segment. The AHB2 power amplifier delivers musical details without introducing the masking effects of amplifier noise and distortion. The performance-related improvementspower output, S/N ratio, THD, and channel separationare not huge, but they are appreciated the increase in weight not so much. The Benchmark AHB2 is the ideal match to the performance limits of High-Resolution-Audio (HRA) formats. THE QUIETEST, CLEANEST AUDIO AMPLIFIER ON THE PLANET.

In order to achieve the new amp specs, Siau utilized THX amplifier design concepts, but he also designed his own signal path design in order to get these impressive numbers and audiophile-accurate audio signatures. BENCHMARK AHB2 POWER AMPLIFIER THE QUIETEST, CLEANEST AUDIO AMPLIFIER ON THE PLANET From the first watt to the last watt, no audio power amplifier offers lower noise or lower distortion than the Benchmark AHB2. “The AHB2 power amplifier was designed from the ground up to deliver the full performance of the DAC2 HGC," he emphasized. It occupies the same footprint as the Benchmark DAC1, DAC2 and DAC3 converters. The SNR of the AHB2 was spec'd at 130 dB (A-weighted) and THD is -115 dB, just about as good as the DAC2’s measurements. The LA4 is available with a black or silver faceplate and is designed to match the Benchmark AHB2 power amplifier. Siau said that the amp has exceeded his expectations - in terms of measured performance. However, the mono switch should also work. Benchmark’s can make cables with bananas or spades on the speaker end against a special order. Biamping is also possible but will require NL4 4-pole cables. The power output goes from 100 W/channel to 380 W single channel. Note the addition of the input sensitivity switch The AHB2 can be bridged and operated as a monoblock. “After all, the performance of the D/A converter is only useful - if it can be delivered by the downstream power amplifier.” CH Precision M1.1 Reference Power Amplifier: 104,000/pair The Swiss-made CH Precision M1.1 is a modular solid state ampthe user can configure the amp for stereo or mono use, as well as for a choice of output-power-delivery modeswith a JFET front end and a class-AB output stage. “It was my goal to create a power amplifier that matched the performance of the DAC2 D/A converter,” Siau explained. The output of the AHB2 will sound exactly like the input. In contrast to an SET amplifier, the AHB2 is designed to be virtually distortion-free. The AHB2 is a much different listening experience. You are completely correct when you say that the difference is dramatic. That said, folks trying to drive the Hifiman HE-6 and Susvara gravitates towards this piece of gear. There seems to be an interest in it for hard to power headphone enthusiasts on the forum even though Benchmark makes the HPA4 which is a headphone amp. 0001% and signal-to-noise/dynamic range measured at more than 130 dB!!!! That is digital-like specs from an analog amplifier, and a source of pride for co-designer and Benchmark VP John Siau. The AHB2 and SET amplifiers are on the very opposite end of the spectrum. The Benchmark AHB2 is a power amp meant to power speakers. The AHB2‘s key highlight is the extremely low noise and distortion. This is not your typical hi-fi sized amplifier. The AHB2 is housed in a compact enclosure that measures only two times a DAC2 (11" W x 9"D to back of connector x 3 7/8"H). Benchmark ahb2 power amp professional#
It features a bipolar-output power section, 180 WPC output RMS, (350W bridged mono), balanced XLR input, three-way input sensitivity switch and dual speaker input options: binding posts and Speakon, a professional termination that uses a twist-on connecter. The $2,995 AHB2 stereo amplifier was designed in conjunction with THX.
