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.
