In contrast to these conventional designs, the AHB2 remains virtually distortion free to the last watt. Class-AB amplifiers tend to do well at high levels, but usually show a gradual increase in distortion energy as the output increases. Likewise, class-D amplifiers often have slew-rate related distortion problems that show up at higher power levels. The AHB2 is virtually distortion-free in the critical first few watts.Ĭlass-A amplifiers often perform poorly at high power levels.
It behaves like a class-A amplifier in the low-power region. The AHB2 does not have either of these problems. Likewise, the dead-band distortion in a class-D amplifier can be problematic at these low output levels. This is the region where the non-musical distortion caused by conventional class-AB push-pull output stages can rise to a high percentage of the audio level. Unfortunately, most amplifiers perform poorly in this low-power region. In either case, the 1st few watts of power are some of the most important to the listening experience. With high-efficiency speakers, most of the audio may be delivered at less than one watt. In a normal listening environment, a comfortable listening level is usually reached with only a few watts of audio power.

Experience the full emotion and detail captured in your finest recordings:
The AHB2's extended frequency response, tight bass control, ultra low noise, and vanishingly low distortion are key parameters contributing to accurate reproduction of high-resolution musical recordings. In contrast, the revolutionary AHB2 was specifically designed to deliver true high-resolution performance. 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.
