"There are many things that come into play when putting together a hi-fi system, one of which is synergy."
"After the arrival of the Benchmark Media Systems AHB2, I immediately thought of the matching HPA4 that colleagues Jaap and Yung were very pleased with."
"The key question, of course, was whether the HPA4 would really provide an audible improvement."
"Well you bet! The synergy between preamp and power amplifier is nothing short of magical, not to mention the DAC3 B that I got from importer Helios for the occasion."
"Not only a few curtains disappear, the whole window is gone."
"This is a great touchscreen that works very intuitively. You never have to think twice to run any function. This is where Benchmark's pro background comes into play."
Killer Feature
"The 'killer feature' on the HPA4 for me is the ability to make each input play equally loud. Adjusting the gain so that different sources and dacs are equalized is a fantastic tool."
"Balance control is also an important feature given the fact that listening spaces are never perfect."
Remote Control
"Remote controls are a pet peeve of mine, but this one is a 'beauty'. It is beautifully made and it fits perfectly in the hand. It has just the right selection of buttons, nothing extra, nothing missing. Adjusting the volume, choosing the inputs and being able to mute every now and then are the most important features.The other settings, which you usually only have to do once, are made via the touchscreen."
HPA4 - Line-Level Preamplifer with THX-888 Headphone Amplifier
"Initially I thought to buy an LA4 (preamp only) because I am not really a headphone aficionado and because I thought that the LA4 would perform slightly better... but Benchmark assured us that the line amplifier is identical in both devices."
"The HPA4 is the best deal because for a limited additional charge you get one of the best headphone amps on the planet."
"The DAC3 B also fits seamlessly into the system. So much so that we prefer it to the Metrum Acoustics Onyx in this setup. Once again proof that synergy is important."
"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.
