DAC2 HGC - 2013 Positive Feedback Writer's Choice Award

"The 10th Annual Positive Feedback Writers' Choice Awards for 2013 - The Best of the Best!"

"Beginning at the end of 2003, PF established its first annual awards for fine audio. The Brutus Award was established for the best that Dave Clark and I had heard in our own listening rooms during that year. You can think of it as our equivalent of an "Editors' Choice" award."

"What an achievement! ... its incredible versatility and over-achieving sonic performance make it more than extraordinary!"

"This DAC just about has it all, ultra versatility and smooth, seductive sonics approaching state-of-the-art. It was such an over-achiever, I put my money where my mouth is; I bought it!"

LA4 - "Best of RMAF 2018" - SoundStage! Hi-Fi

November 01, 2018

"RMAF 2018 was really good, with significant numbers of attendees, and more new-product introductions than I remembered ever seeing there."

"Led by engineer John Siau and based in Syracuse, New York, Benchmark Media Systems has built a sterling reputation for making compact, well-engineered, moderately priced electronics that challenge the state of the art, both on the test bench and in the listening room."

"What I took notice of were the specifications: total harmonic distortion of less than 0.00006%, and a signal/noise ratio exceeding 135dB from 20Hz to 20kHz."

"If those claims are true, and there’s no reason to believe they aren’t -- Benchmark gear has always performed as specified on the test bench -- the LA4 should be about as transparent-sounding a line-stage as you can find at any price."

HPA4 - Lab Report - Paul Miller, Hi-Fi News

"Here's a brand that's aptly named - its products providing a 'benchmark' technical performance. The HPA4 is no exception with its relay-switched stepwise volume attenuator calibrated in 0.5 dB steps over a 'useable' 105 dB range."

"Distortion and noise are vanishingly low."

"The frequency response is ruler flat (+/- 0.01 dB) from 1 Hz - 100 kHz."

"The [line output] source impedance is a sensible 30 Ohms and the maximum output a huge 22 V."

"Via the headphone amp, the maximum voltage is 11.2 V and ... the maximum power output is a substantial 4.4W/25ohm and 7.7W/8ohm."

"So, not only will the HPA4 drive the toughest headphone loads but its ... insignificant -102 dBV (8uV) residual noise also ensures exceptionally quiet backgrounds when listening with the most sensitive headphones/earbuds."

"Distortion is broadly unaffected by loading."

"The source impedance is a low <0.6 Ohms up to 10 kHz, increasing to 0.78 Ohms at 20 kHz."

Hi-Fi News "Outstanding Product" Award

"Benchmark describes its product as a 'reference Stereo Headphone Amplifier and Reference Line Amplifier with Relay Gain and Input Control', which should give you some idea of what's going on here, but only hints at the fact that this is actually two completely separate products packed into one relatively compact unit."

"The headphone section is powered by a power amp from THX, employing the same AAA (Achromatic Audio Amplifier) technology first used by the company in its AHB2."

"Benchmark's line amplifier uses relays for input selection, gain control and muting while four independent 256-step attenuators ... feed the the headphone ... and preamp outputs."

"As PM notes in his Lab Report, this design gives the HPA4 not only outstanding performance, but also rather impressive - to say the least - signal delivery."

"All of a track or two should do the trick, as whether with revealing headphones ... or used as a preamp, the HPA4 simply drops jaws with the sheer impact, openness and vivacity of the way it plays music."

"It was one of those real 'performer in the room' experiences and I was instantly transported back to the time I spent monitoring the recording as it was being made ..."
