Its patented design delivers performance that approaches the limits of the latest high-resolution audio formats. Benchmark's AHB2 power amplifier delivers musical details without introducing the masking effects of amplifier noise and distortion. 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.\u003c\/p\u003e\n\u003cp\u003eUnlike class-D amplifiers, the AHB2 is noise free over its entire 0.1 Hz to 200 kHz frequency range.
