DAC2 HGC - "The audio quality is pretty stunning"
"The audio quality of the DAC2 is pretty stunning and like a lot of high quality amplifiers the first thing to jump out here was the soundstage. This and instrument separation gave a presentation which is hugely revealing and very enjoyable with good recordings although that comes with it an obvious double edged sword (depending on your preferences). After these wow factors came the detail, now I'm not saying the detail is the 3rd best aspect, it's just that it hit me in that order."
"I think the best way to describe the detail is precise and edgy. Combine this machine with a pair of headphones that already display those traits and you have yourself a pretty impressive experience."
"This is a neat, light and well constructed little machine. It's straight forward simplicity and low-key flair seems to reflect it's sound design as well."
"The DAC2 also boasts features like four balanced 32bit DACs, a Bi-driecrional 12v trigger (HGC only) and a configurable coax to name just a few. The latter feature turns one of the digital coax inputs into a digital output, which can pass through Dolby Digital, or DTS (eg. to a home theater receiver) and even bit-perfect DSD."

"The AHB2 easily outperforms the DIY Hypex NC400 I had tested before which used to be the best amp I had tested."
"THD+N versus output level looks far cleaner than anything I have tested before."
"Intermodulation distortion versus power level shows the same story of clean power."
Signal to Noise Ratio:
(unweighted, 22.5 kHz BW)
Ch1: 130.286 dB
Ch2: 130.180 dB
-0.3 dB at 20 kHz
-3 dB down at 200 kHz!!
"Since this is not a switching amplifier, there is no filter there allowing the bandwidth to go to 200 kHz and beyond."
Stereo Power into 4 Ohms:
"We have 185 watts of power at incredibly low distortion of 0.00016%, besting the company specifications."
Bridged Mono Power into 4 Ohms:
"500 watts into 4 ohm! Stunning 0.00026% distortion at 500 watts!!"
"It goes without saying that the Benchmark AHB2 breaks new ground ... gets my strongest recommendation."

"The AHB2 power amps ... are fantastic."
"I use them as mono blocks due to my power hungry speakers."
"I hear clarity, precision and an openness in the treble that I haven't heard in my speakers before."
"The HPA4 line and headphone preamp and the power amps are made for each other..."

"The effortless and free-flowing nature of the Martin Logans paired up nicely with the transparent AHB2 amplifiers."
"The tonality and realism of the instruments were spectacular. An alto saxophone sounded as if it was in the room with me, and the pitch and timbre of both male and female vocals were absolutely spot-on. It was clear that nothing in this system was getting in the way of the music."
"Their room had a remarkable degree of transparency that made every listener feel closer to the music."
