"Ever since Benchmark released the DAC2 Series a few years ago, the D/A’s measured performance, ultra-accurate smooth ESS-chip audio delivery has made, it, er, the Benchmark of D/A converters. Every DAC I get in for review, I always compare to the Benchmark."
"The primary difference from other DAC2 models is the inclusion of balanced XLR AES/EBU input which makes it more compatible with professional equipment and high-end audiophile gear, and the dual stereo buss output."
"The dynamics of a Benchmark DAC2 Series converter is hard to match."
"The DAC2-DX’s headphone amp is robust enough to handle power hungry AKG phones, such as the brilliant AKG-K803, or any ‘phone set you want to connect to it."
"If you like a clean, transparent, yet smooth and detailed D/A converter for your home pro (or larger separate pro facility) or hobbyist studio, the DAC2-DX should be on your short list of DACs to consider."
"I cannot emphasize enough the DAC2's sound quality. If your only experience has been with the old DAC1 Series, you are in for a treat. The DAC2 blows it away in terms of listenability. Significantly smoother, especially with Pop music. Like the DAC2-HGC, the DAC2-DX receives our Stellar Sound Award and an 2015 EAN Product of The Year Award nod in the home recording studio category."

"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."
