Solid State Preamp Reviews

I am certain the quality of life I live is determined by two factors: who and what I give my attentions to, and my ability to observe all that I encounter with an open mind. This approach to living has served me well—especially during this review of the Benchmark Media Systems HPA4 headphone amplifier ($2999).

During the four years that I've reviewed for Stereophile, I've had the privilege of evaluating products from some of the world's best-known audiophile companies: Audio Research, Bel Canto, CH Precision, dCS, D'Agostino, Dynaudio, EMM Labs, Jadis, Krell, Nordost, and Wilson, among others. But one long-standing manufacturer whose exhibits at audio shows invariably inspire ecstatic reports, Germany's MBL, has remained outside my purview.

Upon hearing about this new product from Benchmark Media, the LA4, my mind turned to Laurindo Almeida, Bud Shank, Ray Brown, and Shelly Manne—the original L.A. Four jazz quartet. No such association was intended, however: the "4" merely designates change from previous Benchmark designs.

For those who listen with their ears and not their brain, perfectionist hi-fi offers many surprises.

A friend called me up a few weeks ago and asked if the DAC we both own had received an automatic firmware update he hadn't heard about; something had changed, it wasn't good, and he couldn't figure out what it was. His system's sound was suddenly pale and unfocused.

There had been no firmware update.

Like most serious pursuers of the audio hobby, I've known about J E Sugden & Co. Ltd. for years. For many of those years, though, it was easy to forget about them, and I mostly did—until, quite recently, Sugden gear began popping up at audio shows, including the 2016 Rocky Mountain Audio Fest. In his report on that show, Herb Reichert described the midrange of Sugden's A21SE Signature, a pure class-A integrated amplifier, driving DeVore Fidelity speakers, as "shroom-like" and contrasted the sound with what he called class-D's "fake cocaine." That got my attention.

In the early 1990s, the Compact Disc was all the rage, and vinyl records were being executed en masse. Thirty years later, and oh, how our tables have turned. Mint first pressings of tenor saxophonist Hank Mobley's 1957 album Hank Mobley (Blue Note BLP 1568), which once could be had for $40, now bring upward of $8000. Each. Vinyl continues to enjoy a global resurgence of popularity, while CD sales have plummeted to all-time lows.

What happened? Apparently, yesterday's pops and ticks are today's "warmth," Record Store Day exclusives, and skyrocketing vinyl values. All things old . . .

Sometimes, I feel I'm two people. One, a card-carrying audiophile, is always looking for ways to optimize his enjoyment of multichannel music recordings, a purist pursuit that begins with file playback and leads to DACs, amps, and speakers, while eschewing anything that can complicate or compromise the sound. Thus, while his main system may seem elaborate to outsiders, to him it seems streamlined: NAS>player>DAC>preamp>power amps>speakers. In fact, it's possible to combine the NAS and player in a single device, if that device's CPU and RAM are capable of doing all the tasks—but these product categories continue to evolve so quickly that he prefers to keep them discrete.
