Digital Processor Reviews

Stereophile has favorably reviewed many NAD amplifiers over the decades. One of the most recent was the Master Series M10 class-D streaming integrated amplifier, which I purchased to use as my daily driver after I reviewed it in January 2020. The M10's price included a free license for Dirac Live low-frequency room equalization, which I found invaluable with my long-term reference standmounts, the KEF LS50s. So when I learned that NAD was introducing a 50th Anniversary integrated amplifier, the C 3050 LE, which also included Dirac Live, I asked for a review sample.

When I survey the realms of fancy-pants audio, the first thing I notice are cohorts of luxury-brand manufacturers selling pride of ownership with emblematic faceplates. After that, I spot another type of manufacturer, one that mocks the first type and aims its products at a younger, more working-class demographic, seducing potential customers with how much "truth" they are offering for only $15. But sometimes, when I look beyond the full-page ads and big rooms at audio shows, I discover a rogue manufacturer that is peddling a very specific type of listening experience, which they believe is the best. A listening experience only they could have created. I am grateful for manufacturers like this. They make my job more interesting, and I admire them for their courage in betting on their own taste in music reproduction.

I am relating these observations because this month I'm reviewing a digital converter from an off-the-paved-road audio manufacturer named Benjamin Zwickel. He operates a company called Mojo Audio, which is located in Albuquerque, New Mexico.

Hygge might not be the first word that comes to mind when contemplating the Primare PRE35 Prisma preamplifier, but in Limhamn, Sweden, that is how Primare likes to describe their products. It means "cozy," and it's a very important concept in the Nordic countries, almost a way of life. Another term that appears in Primare's product descriptions is lagom, which loosely translates as "not too little, not too much—just right."

Within seconds after hitting play on the 2006 remaster of "The First Time Ever I Saw Your Face," played back with the dCS Vivaldi Apex DAC, what I thought would be a lovely opportunity to wax nostalgic morphed into something far deeper. The first few bars of the song grabbed us like nothing else we'd listened to over the past 10 days. Flack's complete calm, unwavering focus, and unapologetic intimacy took our breath away. The soundstage was wide, the silence profound, the presentation pristine. The beauty of Flack's voice and passion, enhanced by John Pizzarelli's guitar, Ron Carter's bass, and Ray Lucas's drums, transformed the music room into a holy sanctuary. Toward the end of the first verse, right before "To the dark and the endless skies," I rose long enough to turn off the lights. We sat together in silence, barely breathing.

Stereophile's March 2023 issue includes two follow-up reviews of high-performance digital playback products: the Benchmark DAC3 B D/A processor; and the Rotel Diamond Series DT-6000 DAC Transport (a CD player with digital inputs).

Everyone knows I'm a lucky guy. I was born in Chicago in nineteen-hundred and forty-nine, and as far as I can tell, that was the perfect year to be born. I missed the war, plague, and Depression horrors of the first half of the 20th century, and I witnessed the art, music, and cinema inventions of the second half.

The Topping DM7 DAC ($599.99) is a high-resolution, eight-channel DAC that supports PCM and DSD sources but will not handle any of the common Dolby/DTS codecs. It employs the highly capable and respected ES-9038PRO DAC chip, ESS's flagship. It has just one input, and it's USB. Its eight analog outputs are fully balanced, but they are TRS (tip-ring-sleeve) phone jacks, which are more widely used in pro audio; most audiophiles will require adapters.
