"With DAC, preamplifier and power amplifier, Benchmark knows how to build a bridge between the professional sector and home hi-fi. Very beautiful."
HPA4 - "A Whopping Six Watts into 16 Ohms"
"If you value transparent, precise sound, but at the same time want a certain level of comfort and at least a little elegance, you are in good hands with the Americans."
AHB2 - "A High Degree of Precision"
"The DAC3, HPA4 and AHB2 are all characterized by their wonderfully transparent sound and their high degree of precision. At the same time, sufficient amenities are offered to offer adequate comfort. A successful mix."
"If you are looking for a preamplifier/headphone amplifier that you can live with happily for a long time, you should consider the Benchmark HPA4 at the top of your must-audition list."
"TheHPA4combined with the Benchmark AHB2 power amplifier ranks as the quietest rig I've heard (or not heard)."
"Even with the gain up to full with no signal, there is no hiss, hum, or buzz, even when I placed my ears within a in inch of the drivers on 89 dB sensitive loudspeakers."
"As a headphone amplifier, the HPA4 was first rate. Whether it was my most power-hungry headphones, which currently are the new Abyss Diana Phi, or my most sensitive IERs, such as the Empire Ears Phantoms, there was no added noise or lack of adequate gain."
"The BenchmarkHPA4exhibits virtually no noise, whether employed as a stereo preamp or headphone amplifier, and his highly transparent, with no audible colorations."
197 Rooms - Benchmark Room Makes the Audio Beatnik "Top 3"
"The overall sonic signature of this room had a remarkable sense of ease and purity. Minute details such as a breathy initial saxophone note or a solo vocalist parting her lips and taking a breath before singing were easily discernable. At the same time, they presented all of the musical energy and rhythm contained within the source material. 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."
"My initial impression was simple: TheLA4preamp plays everything that is, and nothing that isn't...Neutrality in Audio... and that's really all this review needs to convey."
"TheLA4preamp may occupy neutral audio country, but it is a sweet piece of audio kit. I love its form-factor. I love its simple operation. And I love that it allows the sound of the signal to flow through to the downstream components."
"The LA4's specifications are unquestionably excellent. When using pro-level balanced interconnects, the LA4 manages a Signal to Noise Ratio (SNR) greater than 135 dB, and Total Harmonic Distortion (THD) of -125 dB."
"The LA4 has a noise floor that is not just low, it's bats-strain-to-hear-it low."
"The Benchmark LA4 is an excellent preamp, an operationally solid spec-monster that also happens to sound great."
"RMAF 2018was really good, with significant numbers of attendees, and more new-product introductions than I remembered ever seeing there."
"Led by engineer John Siau and based in Syracuse, New York, Benchmark Media Systems has built a sterling reputation for making compact, well-engineered, moderately priced electronics that challenge the state of the art, both on the test bench and in the listening room."
"What I took notice of were the specifications: total harmonic distortion of less than 0.00006%, and a signal/noise ratio exceeding 135dB from 20Hz to 20kHz."
"If those claims are true, and there’s no reason to believe they aren’t -- Benchmark gear has always performed as specified on the test bench -- the LA4 should be about as transparent-sounding a line-stage as you can find at any price."
"Benchmark Media Systems used RMAF 2018 to launch two new products that it was able to lump together into one neat little stack."
"On the top is the DAC3 B, which has the same basic circuitry as the company’s more expensive DACs, but deletes the volume control, polarity and mute buttons, and headphone amp found on those models."
"On the bottom is the LA4 linestage preamplifier..."
"The LA4 has two pairs each of single-ended (RCA) and balanced (XLR) inputs, and boasts some impressive specs: THD of less than 0.00006% and a signal-to-noise ratio exceeding 135 dB from 20 Hz to 20 kHz."
"Volume is controlled by dual 256-step attenuators that operate in 0.5 dB increments."
