Integrated Amp Reviews

In the mornings, just before I leave for work, I power up the system, turn the volume down low, and set the CD player to Repeat. I like to think that if I play calm, soothing music while Ms. Little and I are away, the cats will feel less alone and more relaxed. It's also nice, on returning home from work, to walk into a room filled with music. One evening a few weeks ago, I stepped into the apartment, dropped my bags to the floor, settled down into the couch with my iPhone, and began scrolling through text messages. I'd been seated for only a moment before I had to turn my attention entirely to the sound of the system, which, even at a very low volume, sounded warm, detailed, and unusually good—unbelievably, almost unbearably engaging.

Older audiophiles remember the splash NAD made in the late 1970s with the introduction of their 3020 integrated amplifier ($175). Ridiculously cheap, it looked graceful and sounded warm, inviting, and holographic. Removable jumpers between the 3020's sections permitted enthusiasts to determine whether the magic resided in its preamp, its power amp, or in some synergy of both.

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.

When I asked NAD for a sample of their Masters Series M50.2 digital music player, which I reviewed in the December 2017 issue, they also sent me a Masters Series M32 DirectDigital integrated amplifier, which had also been introduced at the 2017 Consumer Electronics Show. Costing $3999, the M32 offers a continuous power output of >150W into 8 or 4 ohms. The M32 is the same size as the M50.2, and its smart-looking combination of matte black and gray-anodized aluminum panels make it look identical to the player, except for the black volume-control knob to the right of the front panel's four-color touchscreen, and the ¼" headphone jack at bottom left. It even has the same eight ventilation grilles inset in the black top panel.

On the cold and sunny morning of February 19, 2020, a dozen or so audio critics and writers gathered at Gilmore's Sound Advice on New York's far West Side to see some new NAD and DALI products that had been unveiled the prior month at CES. It was a friendly group, and we kibitzed over coffee before clustering in the arranged seats for presentations and auditions. I doubt any of us realized that it would be the last time for the foreseeable future that we would experience this familiar rite.

Audiophiles are oblivious to the low-end music-reproduction medium that's currently staging a comeback: the cassette tape (footnote 1). I've adopted the cassette craze in my own small way. I glory in the trusted mixtape, which I play in the stereo cassette deck of my 1990s Toyota. An automobile is a dearly cherished possession in New York City; when I cruise the outer boroughs on Sunday, I want tunes galore. So I retrieved my 1996 Aiwa cassette deck, and, attic-bound as it had been for 20 years, it was in need of repair. Via Yelp, I came across Hi-Tech Electronics, a small repair-everything-electronic shop at the east end of Canal Street, in New York's Chinatown, and a mother lode of classic audio gear and audiophile nostalgia.

The $395 NAIT, rated at 20Wpc, is a good-sounding little amp. It's very open and spacious-sounding, but, like the $250 Rotel RA-820BX, sometimes sounds a little hard in the upper registers.
