DAC2 - "Taking the DAC1 ... and improving upon it"
"I remember writing up a large group test, for a national UK Hi-Fi magazine, several years back, on DACs. I’d never heard of Benchmark before but the DAC1 trounced all of the other DACs on test to win the crown for that test. I was more than impressed and vowed to keep an eye on the brand from that day forward."
"Benchmark says that this, the latest iteration in the range, is superior in terms of sound quality to the DAC1 and that it features an advanced digital filter design plus a new high-sample-rate Asynchronous USB Audio interface."
"Immediately, right from the off, I was seriously impressed with the DAC2."
"It’s been an education, reviewing this group of Benchmark products because the one element that threads its way through all of them is low noise and I love a company who targets noise as the enemy of the hifi-loving public. The DAC2 shows this attention to low noise detail in abundance because the clarity on offer is excellent. By doing this alone, there is so much more detail on offer and buzzing around the soundstage."
"The ear suddenly picks up a host of new information, not just because the noise has gone but because the noise removal separates the instruments and allows them to perform as individual instruments in a group scenario, if you see what I mean. "
"Highlights? There’s plenty. The bass is powerful, meaty and dryly solid with fine edges and character. Vocal delivery is sensitive in its approach while the guitar playing hits a tremendous groove. The enhanced tonal accuracy gives the song a natural air and a sense of confidence."

"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."
