High-quality playback of digital audio is evolving in two opposed directions. One is where a smart wireless loudspeaker, like the KEF LSX 1 or DALI Callisto 6 C, 2 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, 3 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.
Like the M32, the M10 offers analog and digital inputs, but here the BluOS functionality, with its network, Wi-Fi, and Bluetooth connectivity, is included rather than optional. Yes, both amplifiers use a digital output stage, but while the M32 uses a “DirectDigital” amplifier that takes a digital signal as its input, the M10’s “Hybrid Digital” amplifier takes in an analog signal. The M10 also offers 50W less power than the >150W claimed for the M32. But NAD specifies that the M10 will offer “Dynamic Power”—ie, when the power demand is short-lived, as it would be with musical transients—of 160W into 8 ohms and 300W into 4 ohms.

Buckeye PURIFI EIGENTAKT 1ET9040BA1
Back in 2016,' I documented the rise of class-D amps using the early Tripath technology. Used in the Bel Canto eVo 200.2, TriPath cracked open the door to the High End but was never admitted due to a dim and opaque treble.

The Clearaudio allowed each mix, each sonic artifact, to reveal its unique character.
Gryphon Audio Designs Diablo 333
What's in a name? Denmark-based Gryphon Audio Designs laid down a marker when company founder Flemming Rasmussen chose that name in 1985. Browsing through the current Stereophile Recommended Components list, I only found one other manufacturer that utilizes an animal moniker.
The Rega Naia Turntable. Add Lightness.
To watch as Rega very slowly expands its turntable offerings upmarket requires the patience of a Thomas Pynchon addict waiting for each new tome from the notoriously slow-working and reclusive author.

Record Player Revelations
Like romance or car racing, the act of playing records is tactile by design. Like drifting through curves or making out, spinning vinyl is a learned skill that requires users to touch everything with practiced assurance.
Taking Care of Business
As Jim Austin wrote in this space in the December 2024 issue, following a medical procedure that he had in mid-October, he needed to take several weeks' leave to recuperate. He delegated the magazine's production to Managing Editor Mark Henninger, AVTech Editorial Director Paul Miller, and myself. The three of us worked with copy editor Linda Felaco and longtime art director Jeremy Moyler to produce the issue you hold in your hands.
