"Benchmark Media Systems used RMAF 2018 to launch two new products that it was able to lump together into one neat little stack."
"On the top is the DAC3 B, which has the same basic circuitry as the company’s more expensive DACs, but deletes the volume control, polarity and mute buttons, and headphone amp found on those models. The omission of those features is the reason for the B -- it means basic -- as well as a price that’s lower than its other DACs."
"On the bottom is the LA4 linestage preamplifier..."
"The LA4 has two pairs each of single-ended (RCA) and balanced (XLR) inputs, and boasts some impressive specs: THD of less than 0.00006% and a signal-to-noise ratio exceeding 135 dB from 20 Hz to 20 kHz."
"Volume is controlled by dual 256-step attenuators that operate in 0.5 dB increments. Another feature is a touchscreen that can be used to adjust channel balance, to rename or offset the level of inputs, and to adjust screen brightness, as well as other things."

"Before I dig into the sound of the LA4 it is important to know that it employs a wide bandwidth design. The LA4’s bandwidth is specified at 0.2 Hz to 500 kHz."
"Most of the wide bandwidth designs I have heard exhibit ... a purity in tone with superb timing and speed ... the LA4 proved to be no exception."
"The Benchmark LA4 yielded a change that was quickly apparent in several areas. Notably were; bass, upper midrange, treble, low-level listening, and the ability to distinguish the colorations of other components that were contributing to my overall sound."
"Acoustic guitar, piano, and harmonica among many other instruments are presented with speed, clarity, and coherency that made them sound more “present” in the room and less like a recording."
"The Benchmark LA4 is simply the most transparent, least colored, and most revealing component I have had in my system to date. I look forward to it joining my stable of reference components."

"This little unit will change the way you look and listen to amplifiers."
"My first taste of this remarkable new amplifier came earlier this year in April at Chicago's AXPONA where I discovered it driving a newly redesigned Studio Electric Pasadena loudspeaker, also bearing the Benchmark trademark. Now called the SMS1, the Pasadena's crossover had been reworked by Benchmark, upgraded with very low tolerance components, and the new look, more in line with the look of the rest of the Benchmark product line up, had been adopted."
"The subsequent sound in this room was one of the most musically engaging I encountered at this year's event, a remarkable result considering its modest overall system price of just over $7000, sans source."

Jim Austin wrote, "The DAC3 was all about depths, in several respects . . . I heard deeper into the music."
The concise conclusion to John Atkinson's Measurements sidebar: "All I can say is 'Wow!'"
In a Follow-Up, Jim Austin wrote of using the Benchmark processor with the same company's AHB2 power amp—a combination of high source output voltage and modest amplifier gain that he describes as "optimal for minimizing noise and distortion"—and reported hearing "richer and more interesting" reproduction of very subtle details.
