"I believe it is the purest sounding and lowest noise amplifier in my experience."
"Is the AHB2 the “perfect amplifier?” The truth is that it could be when paired synergistically with certain components and speakers."
"What is perhaps most impressive about the AHB2 is its very natural presentation of brass horns, piano and percussion in general."
"The Benchmark AHB2 is a powerful and efficient amplifier with prodigious low levels of noise and distortion. The fact that it is also very musical and non-fatiguing, courtesy of THX’s patented AAA™ technology, is the icing on the cake. Benchmark Media and THX have a lot to be proud of for the development and implementation of the new technology the AHB2 represents."
"The AHB2 provides deep, impactful, and articulate bass, a very musical and transparent midrange, and ultra-clean high frequency reproduction."
"In addition to the AHB2’s impressive bass performance, the midrange sounds extremely pure and clear, not only on vocals, but on many other midrange instruments such as brass horns, woodwinds, piano, and strings of all kinds. But it isn’t merely the stunning clarity of the Benchmark amp that lets one know it’s very special, it is the musicality and authenticity one hears from his or her favorite recordings."
"I very much enjoyed my time evaluating the Benchmark AHB2 amplifier and can heartily recommend it to those seeking one of the lowest distortion and lowest noise amplifiers on the planet—one that is very musically transparent and easy on the ears to boot."
