"More apparent low-level detail" - KR
"In his listening tests, Kalman Rubinson discovered 'much more apparent low-level detail in already-familiar recordings' - a characteristic he credited to the Benchmark's evident noiselessness - and a tonal balance that 'sounded more right' than any of the other amps on hand."
"An extraordinary amplifier" - JA
In measuring the AHB2 and attempting to confirm its specified very high signal/noise ratio, John Atkinson observed nonlinearities in his testing equipment that 'Haven't affected the measured performance of other amplifiers I've tested, but they were detectable with the AHB2's very low intrinsic distortion and noise.' His conclusion: 'an extraordinary amplifier.'"
"Kalman Rubinson's last word: 'bargain'"
Stereophile 2016 Recommended Components, April 2016
Read the Stereophile Bench-Test Report


Stereophile rates recommended components by placing them in one of 6 classes; A, B, C, D, E, and K. Of these, the highest rating is "Class A". Benchmark shares this small and elite class with amplifiers costing 10 to 20 times more than the AHB2.
"Best attainable sound for a component of is kind, almost without practical considerations; 'the least musical compromise.' A Class A system is one for which you don't have to make a leap of faith to believe that you're hearing the real thing."

"The DAC3 was all about depths, in several respects...I heard deeper into the music."
"All I can say is Wow!"

"Benchmark's LA4 is the widest-bandwidth, widest-dynamic-range, lowest-noise, lowest-distortion preamplifier I have encountered."
- John Atkinson
"The LA4 is probably the most transparent and revealing audio component I've ever used. It does not seem to leave any fingerprints on the sound."

"The LA4 preamplifier was the widest-bandwidth, widest-dynamic-range, lowest-noise, lowest-distortion preamplifier I had encountered at that time. . . . To those virtues, the HPA4 adds equally superb balanced and single-ended headphone outputs."
