The AHB2 stereo power amplifier introduces groundbreaking advances in power amplifier design and performance. Its entirely new patented technology eliminates most sources of distortion while extending the dynamic range well beyond that of most high-end amplifiers. High-resolution audio recordings are now available in a variety of digital formats, but none of these formats can be experienced to their full potential using a typical power amplifier. Only the AHB2 power amplifier is designed to deliver the details, texture, and dynamic range of the finest best high-resolution recordings. There’s a huge problem with HD music today. Recent advances in high-resolution digital formats have well outpaced most existing amplifier technologies. It is now possible to produce and distribute recordings that have dynamic ranges that exceed 120 to 125 dB. However, it is hard to find a power amplifier that can deliver more than 100 to 105 dB of dynamic range. Most of the advantages of the high-resolution formats are lost in even high-end setups. Benchmark saw clearly that the differences between a 16-bit recording and a 24-bit recording cannot be fully appreciated through a power amplifier that can only achieve 16 to 18-bit performance. That’s why we created the AHB2, a perfect match to the new high-resolution digital formats. Benchmark's AHB2 power amplifier delivers musical details without introducing the masking effects of amplifier noise. The dynamic range of the AHB2 approaches 130 dB, making it 10 to 30 dB quieter than the typical audiophile power amplifier. 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.
