"Here's a brand that's aptly named - its products providing a 'benchmark' technical performance. The HPA4 is no exception with its relay-switched stepwise volume attenuator calibrated in 0.5 dB steps over a 'useable' 105 dB range."
"Distortion and noise are vanishingly low."
"The frequency response is ruler flat (+/- 0.01) dB from 1 Hz - 100 kHz."
"The[line output] source impedance is a sensible 30 Ohms and the maximum output a huge 22 V."
"Via the headphone amp, the maximum voltage is 11.2 V and ... the maximum power output is a substantial 4.4W/25ohm and 7.7W/8ohm."
"So, not only will the HPA4 drive the toughest headphone loads but its ... insignificant -102 dBV (8uV) residual noise also ensures exceptionally quiet backgrounds when listening with the most sensitive headphones/earbuds."
"Distortion is broadly unaffected by loading."
"The source impedance is a low <0.6 Ohms up to 10 kHz, increasing to 0.78 Ohms at 20 kHz."

"The Benchmark AHB2 is a very fine sounding, easy to live with, zero-maintenance power amplifier that has enough power for most systems. If more power is needed, two amplifiers configured for mono can provide it. The decision to purchase the review sample and make the Benchmark AHB2 a new, long term reference took over a month of listening and comparisons."
"The outstanding musicality of the Benchmark AHB2 takes some time to convince the listener of its wholly musical presentation. This subtle excellence assures long term satisfaction."
-10 Audio, Perfect 10 Award
Alpha-Audio.net tested 10 DACs side-by-side. Only one received the "Alpha-Audio Approved" award. That DAC was the Benchmark DAC3.
"Are you looking for the best DAC (d/a converter) in the price range from 1500 euro to 2500 euro? That’s great! Because we’ve put ten beauties side by side. And we tested it live on camera for you."
"It was incredibly instructive to put so many converters side by side. We clearly hear differences - and the viewers could as well."
"One of the models we all agreed on is the benchmark DAC3. This is a delicious musical product. Virtually no coloring, nice stereo image and plenty of inputs."
DAC3 - Alpha-Audio Approved!
"Prior to reviewing these Benchmark components, I had heard the company’s products powering some of my favorite-sounding rooms at several audio shows. Based on what I’d heard at these shows, I was eager to hear how this equipment could perform in my own listening room."
"Listening to the Benchmark gear in my own room, I felt an immediate and gratifying emotional connection to the music I was hearing."
"The LA4 and AHB2 tear down so many of the usual walls that come between the listener and the music."
"If you value transparency and accuracy, the LA4 and AHB2 will perform beyond your highest expectations."
