This month's music feature, by Mike Mettler, is an interview with John Doe, best known as cofounder, in 1977, of the legendary punk band X. During X's long recording career, Doe's urgent voice has offset the starkly contrasting voice of co–lead vocalist (and songwriting partner) Exene Cervenka, who was Doe's girlfriend before she joined the band; it's one of the most recognizable sounds in punk. Over 45 years, X has continued to record (sparingly) and to evolve, from the literate punk of Los Angeles—to me one of the great albums ever, in any genre—through Wild Gift, which leans toward country, to Under the Big Black Sun, which went in several directions at once: rockabilly, funk, folk, pop, and beyond.

At the beginning of this century, when the vinyl resurgence was at best nascent and few believed it would be as strong as it is today, Boulder Amplifiers manufactured a phono preamplifier that cost $29,000. I reviewed that model, the 2008 (now discontinued), in the July 2002 issue. With a power supply that would probably be more than adequate for a high-wattage power amp, it was built to a standard approached by few other makers of phono preamps...

With his lines of power amplifiers and preamplifiers well established, Dan D'Agostino—the founder, CEO, and chief designer of the company that bears his name—set about designing a phono preamplifier.

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.
