AHB2 Review - Sandu Vitalie, Sound News

by Benchmark Media Systems February 28, 2022 5 min read

"The AHB2 might look small and lightweight, but thanks to its clever engineering and power supply implementation, this little fellow could still deliver 190 Watts in 4 Ohms and 100 Watts in 8 Ohms, while maintaining an undetectable noise floor and distortion."

"For the craziest folks out there, you can even bridge two pieces together for ~580 Watts in 4 Ohms and 380W in 8 ohms."

Build Quality

"Thor almighty! This thing has some amazingly thick panels all around it, adding a level of confidence and refinement. It looks plain and industrial, but I really dig its minimalist body."

Protection Systems

"You know what I like the most about it? Its bullet-proof protection systems!"

"Fault conditions silently mute both output channels in order to protect the speakers and amplifier from any damage."

"I somehow forgot ... blasting 380Watts of power into my KEF Reference 3 after pressing the play button. A microsecond didn’t pass and both AHB2 engaged their protection circuits and muted themselves without causing any harm to my loudspeakers."

"For almost a year now, AHB2 saved my speakers twice."


"The key words with AHB2 are: world-class detail retrieval, absolute transparency, lightning-fast transient response, an open wide soundstage with a very precise layering and positioning of the notes around the listener, all tightly controlled with an iron grip, never sounding too mellow, sluggish or all over the place."

"The highest compliment I can give to AHB2 is that I purchased not one, but two units with my hard-earned money. These weren’t loaner units and this wasn’t a sponsored review and you can draw your own conclusions."

"When I’ve received the mighty Hifiman Susvara, I felt overwhelmed by…disappointment. I said to myself: “This is really it? This is how the world’s best headphones are sounding?”"

"Months later, I’ve received a special adapter cable so I could power them with all sorts of integrated and power amplifiers (speaker amplifiers) and that’s when I felt connected to the all known universe, turning them into a gemstone of a headphone."

Benchmark AHB2 Power Amplifier – My Daily Driver V2.0

"Holy mother of Thor, this is dynamics, speed, transient response, resolution and transparency incarnate into a single metal box. There isn’t a clearer, a more resolving or a more transparent sounding amplifier out there, this is a wire with gain amplifier that doesn’t add anything into the mix."

"You can’t get a more impactful, a faster or cleaner sounding amplifier.
