"Benchmark's LA4 is the widest-bandwidth, widest-dynamic-range, lowest-noise, lowest-distortion preamplifier I have encountered."
- John Atkinson, Stereophile
"I measured the Benchmark LA4's performance with my Audio Precision SYS2722 system."
"The preamplifier's frequency response in both balanced and unbalanced modes was flat from 10Hz to 200kHz."
"Channel separation was simply superb, at >140dB, R–L, and >132dB, R–L, below 2kHz, respectively decreasing to 130dB and 112dB at 20kHz. The superb separation measurement is a testament to excellent circuit-board layout."
"I looked at the spectrum of the distortion at a similarly high output level; while the second and third harmonics can be seen, these are still at astonishingly low levels: each harmonic is at or below –120dB (0.0001%)."
"Tested for intermodulation distortion in balanced mode with an equal mix of 19 and 20kHz tones at peak level of 5V, the second-order difference product at 1kHz was effectively absent, and the higher-order products all lay at or below –114dB (0.0002%)."
"The afternoon before the start of the show I ran into John Siau of Benchmark Media Systems. He says to me quietly, “make sure you stop in our room, we have a surprise!” With curiosity suitably piqued, Co-Editor Jim Clements and I paid a visit ..."
"The results were pretty astonishing. A stable, enveloping stereo image that was devoid of any distortion whatsoever."
- Carlo Lo Raso, Secrets of Home Theater and High Fidelity
"Sound was extremely well-integrated and controlled, and the bass memorable."
"The Note received signal through the introductory version of the company's Liquid Cables. Each cable contains 27,000 wires. The company's introductory Elephant memory player joined Benchmark Media's AHB2 power amps, DAC3 B D/A processor, and interconnects."
"With the aid of a forthcoming DEQX HDP4 processor that's due in the fall, 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."

"Laufer Teknik - The Note line array - The most immersive listening experience I had the entire show."
"There is no sweet spot because everywhere is the sweet spot. Even behind the speakers sounded incredible!"
"SVS Subs doing the low end work and Benchmark 380 watt class H monoblocked amps driving the arrays."
"I spent an extended amount of time in this room."
