DAC3 B and AHB2 - Driving Laufer Teknik Note Line Array
Two AHB2 bridged-mono amplifiers were driving the 4-Ohm line arrays (48 drivers per side).
"Sound was extremely well-integrated and controlled, and the bass memorable."
The Note Line Array
"Laufer Teknik claims that the speaker has 360° dispersion up to 10kHz and 180° dispersion above that—when I walked around the speaker, sound was loudest in the front-firing direction—50 to 100 times less distortion and up to 200 times the dynamic range "of a typical D'Appolito design," and the ability to work in a "really large room." The Note has no crossover above the subwoofer, stands 87" tall, is a mere 2" wide and 2.5" deep, and weighs only 40lb."
Two DAC3 B Converters - One for the Array, and One for the Subs
"The Note received signal through Benchmark Media's AHB2 power amps, DAC3 B D/A processor, and interconnects."
Two AHB2 Power Amplifiers - Bridged Mono Mode - One per Array
"The system sounded super on a 16/44.1 file of the famed rendition of Copland's Fanfare for the Common Man, recorded by Eiji Oue and the Minnesota Orchestra for Reference Recordings."

LA4 - Receives Stereophile's Top Rating for Preamplifiers
"Benchmark's LA4 is the widest-bandwidth, widest-dynamic-range, lowest-noise, lowest-distortion preamplifier I have encountered."
- John Atkinson
"The LA4 is probably the most transparent and revealing audio component I've ever used. It does not seem to leave any fingerprints on the sound."

HPA4 - Stereophile 2025 Recommended Component - Headphone Amplifiers
HPA4 - Receives Stereophile's Top Rating for Headphone Amplifiers
"The LA4 preamplifier was the widest-bandwidth, widest-dynamic-range, lowest-noise, lowest-distortion preamplifier I had encountered at that time. . . . To those virtues, the HPA4 adds equally superb balanced and single-ended headphone outputs."
