"The 10th annual AXPONA was the largest yet with an expansive array of speakers, amplifiers and turntables on display across a staggering 197 listening rooms."
"Certain rooms featured systems most enthusiasts could probably afford at some point in their lives, and other rooms catered to the small well-heeled handful who are willing to spend extravagantly to obtain the best possible sound. That’s why I divided my top rooms into two categories: the best three “reality” rooms where the systems were more reasonably priced and the best three “dream” rooms where cost was no object."
"Benchmark teamed up with Martin Logan to drive a pair of their Impression ESL 11A electrostatic speakers with their AHB2 power amplifiers in a bridged-monoblock configuration. The source was an Aurender A10 streamer fed through their own DAC3 B and an LA4 preamp."
"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 discernible. 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."

"I don't think it is sterile sounding at all ... it is very neutral."
"In the studio, neutral, flat and detailed are on the top of my list."
"The HPA4 is speeding up my work, helping me make better decisions."

"It has already been noted in previous reviews that the professional market often offers products that may also be of interest to the 'ordinary' consumer. In Japan in particular, home systems often consist of a mix of consumer equipment and (vintage) professional items."
"Benchmark was founded in 1983 and started building professional audio equipment."
"The goal, from the outset, is to build sound-transparent equipment of the highest quality. The employees are musicians, audiophiles and audio technicians. So sound quality is top notch."
"The HPA4 and LA4 are preamplifiers and largely identical. The HPA4 also has a built-in headphone amplifier."
"The Benchmark HPA4 and LA4 preamps deliver a very high quality neutral and transparent signal."
"Developed from a professional focus on sound reproduction, they bring the essence of the recording closer to the listener."

"Before I dig into the sound of the LA4 it is important to know that it employs a wide bandwidth design. The LA4’s bandwidth is specified at 0.2 Hz to 500 kHz."
"Most of the wide bandwidth designs I have heard exhibit ... a purity in tone with superb timing and speed ... the LA4 proved to be no exception."
"The Benchmark LA4 yielded a change that was quickly apparent in several areas. Notably were; bass, upper midrange, treble, low-level listening, and the ability to distinguish the colorations of other components that were contributing to my overall sound."
"Acoustic guitar, piano, and harmonica among many other instruments are presented with speed, clarity, and coherency that made them sound more “present” in the room and less like a recording."
"The Benchmark LA4 is simply the most transparent, least colored, and most revealing component I have had in my system to date. I look forward to it joining my stable of reference components."
