"Better performance than DACs ten times its price"
"I started reviewing the DAC2 HGC with ordinary CD-standard files, because I'm most familiar with them and have to say that the Benchmark DAC2 HGC impressed me from the get-go with the sparkling, effervescent character of its delivery: lively and entertaining with a lovely freedom to the sound. 'Effortless' is the word I'd say best described it."
"I was able to my use my nocturnal awakenings to extend my reviewing into the wee hours without disturbing the family by evaluating the headphone stage of the DAC2 HGC. Using the HD800s, the high treble performance was beautifully clean and etched, and the midrange warm to slightly-full-bodied, but never so much that clarity was lost at the expense of warmth."
"I could hear no circuit hiss at all when listening through the DAC2 HGC. I took the opportunity to listen carefully for mains hum ... but I came up empty on this one as well, I couldn't hear any mains hum ... or harmonically-related overtones."
"I was so entranced by the DAC2 HGC's performance as a DAC and as a headphone amplifier that I spent almost all my allocated review time using it in those applications, completely forgetting that is was also an analogue preamplifier ... and a true analogue preamplifier, because signals input to A1 and A2 remain completely in the analogue domain: there is no conversion to digital as there is in most other DACs that have analogue inputs."
"The sound as converted by Benchmark's DAC - rather than the external DAC I usually use - was so much better that I pretty much on-the-spot decided that I was going to replace my own DAC with a Benchmark DAC2 HGC. Once I'd decided that, I realized that ... I could simplify my system ... by getting rid of my preamplifier as well. For me, this was an epiphany ... I finally understood what the concept of the Benchmark DAC2 HGC's existence was all about: it's about reducing the component count in your system, and about keeping analogue in the analogue domain and digital in the digital domain. Pure perfection."
"Investing in a Benchmark DAC2 HGC will involve getting rid of the pre-existing notions you have about what components should be in a high-end audio system ... you should now be thinking Source(s) - Benchmark DAC2 HGC - Amplification - Loudspeakers. That's it."

"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..."
- Ulrike Schwarz, Anderson Audio NY
"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."
