In a recent interview by The Poor Audiophile, Laurie Fincham, Vice President of Audio Research at THX, describes the 9-year process that led to the introduction of the revolutionary THX Achromatic Audio Amplifier technology used in the Benchmark AHB2.
"The first thing you need to know about Laurie is that he’s an audiophile’s audiophile. He’s an engineer, music lover, and also a musician..."
"Talking with Laurie was a bit intimidating. For those unfamiliar with Laurie’s distinguished background ... Laurie’s work has garnered him several industry awards including the prestigious AES (Audio Engineering Society) Silver Award..."
"Laurie and I spoke a bit about existing amplifier topologies. “The Class A analog amplifier is a luxury,” he said. “Big, expensive, beautiful, but hot.” We talked about other topologies including recent moves to make audiophile Class D amplifiers. “Most people think Class D is a recent innovation,” Laurie said. “Class D is, in fact, as old as solid state and goes back to the late 50s or 60s.”"
"Instead of building upon existing technologies, Laurie and his team decided to design a better amplifier technology from the ground up. Laurie was quick to point out, “We didn’t invent or reinvent the amplifier. Instead, we looked at the shortcomings, the physics, and developed a technology to deal with that. We were motivated to do better. We didn’t stop.”"
“We’ve been working on the amplifier since 2006 ...
"My initial impression was simple: The LA4 preamp plays everything that is, and nothing that isn't...Neutrality in Audio... and that's really all this review needs to convey."
"The LA4 preamp 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."

"The headphone section, with its choice of 6.35 mm stereo or four-pin balanced XLR connectors ... really impresses with a smooth signal delivery."
"While on the one hand it can rock out when it needs to – its prodigious output means it can give as much power as your headphones can take – its sheer impact, openness and vivacity is jaw-dropping."
"An immaculate all-analogue design, the aptly named Benchmark is both technically and sonically as good as it gets."

Stereophile's editors chose 10 products to receive their top award, the "2018 Product of the Year - Editor's Choice Award". Two Benchmark products made this exclusive list - the AHB2 power amplifier and the DAC3 HGC D/A converter.
"I was impressed by this revolutionary stereo amplifier but it became an obsession when I mated three as monoblocks to a trio of Benchmark's DAC3s."
"The AHB2 is deadly silent, musically revealing, surprisingly compact, and quite powerful."
- Kalman Rubinson
"Benchmark has created a long line of DACs (several of which I've purchased) that present recordings with as little embellishment as is possible at their price points. The latest incarnation, the DAC3, is no exception, and excels at presenting the unvarnished truth, as the artist intended."
