High-quality playback of digital audio is evolving in two opposed directions. One is where a smart wireless loudspeaker, like the KEF LSX or DALI Callisto 6 C, needs to be connected to a simple source of data. The other is where a smart amplifier takes the data from wherever it needs and sends it to a pair of dumb loudspeakers. NAD's Masters Series M32 integrated amplifier ($4848 with its optional MDC DD-BluOS module), which I reviewed in May 2018, is a great-sounding example of the latter approach.

In the spring of 2019, NAD introduced the Masters Series M10 ($2749). At first I assumed that the M10 was a stripped-down, less-powerful version of the M32, but the new amplifier offers a unique set of features.

There is change, and also continuity, at Wilson Audio Specialties, the company founded in 1974 by recordist and loudspeaker designer David A. Wilson. David's son Daryl Wilson was appointed president and CEO in 2016. David Wilson passed away in 2018. And in 2019, Wilson Audio Specialties released the Sasha DAW loudspeaker ($37,900/pair), designed by a team led by Daryl Wilson and named in honor of his father.
