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.
