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 ...
AHB2 - Class A Recommended Component - Fall 2018 - Power Amps
'Class A' is Stereophile's highest classification for recommended components. Very few components receive this elite classification. Stereophile defines 'Class A' as follows:
"Best attainable sound for a component of its kind, almost without practical considerations; "the least musical compromise." A Class A system is one for which you don't have to make a leap of faith to believe that you're hearing the real thing."
DAC3 HGC - Class A+ Recommended Component - Fall 2018 - Digital Processors
'Class A+' is Stereophile's highest classification for digital processors. Stereophile defines Class A and the digital processor Class A+ as follows:
"Best attainable sound for a component of its kind, almost without practical considerations; "the least musical compromise." A Class A system is one for which you don't have to make a leap of faith to believe that you're hearing the real thing. With Super Audio CD, DVD-Audio, and Hi-Rez PCM and DSD files now available, we have created a new Class, A+, for the best performance in those digital categories."
AHB2 - "Tightness, accuracy and punch"
"The most identifiable positive trait (there are many) of the AHB2, and that is low end control. Tightness, accuracy and punch."
"The AHB2 has power in spades, especially with two units running in mono mode."
"A single amp in stereo will suffice for most normal situations, and was in full control of all sonic responsibilities with every pair of loudspeakers we threw at it."
"The low end tightness and thrust is just where it should be, and pass though information is the name of the game."
"The sound of the amplifier is true to source and one that takes many queues from the production world of balance and monitoring."
"... will rock the house (or sooth the baby to sleep)."
