Benchmark has been known through professional DACs with audiophile quality. Now they are introducing a power amplifier.

In the power amplifier AHB2, Benchmark claim to have implemented new patented technology that eliminates sources of distortion. They believe further it while most amplifiers have dynamics limited to 100 - 105dB, in AHB2 they have  earned a dynamic range throughout 130dB. This will be a great advantage in today's Hires recordings with large dynamic range. The frequency response to AHB2 ranging from less than 0.1 Hz to over 200kHz.

Benchmark has implemented technology developed by THX to eliminate crossover distortion. By doing this they claim to allow entering high damping factor without having sideeffect with crossover distortion.

The name AHB2 reflects the founder Allen H. Burdick, who died in September.

Preliminary specifications are obtained from Benchmark`s websites.
