"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."
"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."

"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.

"Today, is a very special day for me, since I believe I am hearing the best overall performance out of my headphones."
"The distance performance-wise between HPA4 and my second-best headphone amp is Night and Day!"
"This headphone amplifier and line pre-amplifier receives my highest recommendation and scores the highest rank in my book."
"It spoiled me so much, that for the past 3 days I’m waking up at 5 A.M. so I can listen, tap my feet and head-bang just a little bit more. I for one, started saving for one, I’m sorry but I can’t go back to regular amps."
"Without a doubt Benchmark HPA4 is an end-game, top of the line headphone amp – it’s The One to rule them All."
