Integrated Amp Reviews

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.

Some among us remember a time when audio was divided into rival interests. On the left side of the pond was the New World, where left-brainers believed that vanishing harmonic distortion meant that "all amplifiers sound the same," and that good loudspeakers are a high-fidelity audio system's most important components. Across the waves, so-called flat-earthers claimed that the most important part of the playback chain was the turntable. (Of secondary importance were the tonearm and cartridge, followed by the preamp and amplifier. Loudspeakers were deemed relatively unimportant.) In the 1980s, this extremist idea of the "front end first" captured the imaginations of audiophiles, mostly in the Mother Country.

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.

In an industry whose newest products are often as discouragingly unaffordable as they are short of the sonic mark, the Naim Audio Uniti ($3795) stands out. In a single reasonably sized box, the Uniti combines the guts of Naim's Nait 5i integrated amplifier and CD5i CD player with various additional sources: an FM/DAB tuner, and interfaces for an iPod, a USB memory stick, an iRadio, and a UPnP-compatible connected computer or server—all for the price of a very good television set.

They spoiled all my fun.

When I receive a product sample for review, I look forward to taking photos while I unpack the thing, as a guide to repacking for later on. This company provided an illustrated packing list—it was the first thing I saw on slitting open the carton. I look forward to crafting amusing remarks about poorly written or whimsically translated owner's manuals; this company provided the clearest, most comprehensive manual I've ever seen. I look forward to having some sort of anomalous event—smoke, noise, or smoke and noise—to write about. This product offered nothing of the sort.

"Onkyo Returns to its Stereo Roots to Debut New Digital Amplifier Technology." This heading of the press release for Onkyo's A-9555 digital integrated amplifier was surely intended to warm the cockles of the two-channel audiophile's heart. Some of us remember the Onkyo Grand Integra amplifiers of the 1980s, which were considered competitive with the big Krells and Mark Levinsons of the day. To refresh my memory, I looked through my Stereophile archives and found the December 1985 issue (Vol.8 No.8), which included Larry Greenhill's review of the Grand Integra M-510, a 300Wpc power amplifier covered in lacquered persimmon wood, weighing 139 lbs, and costing $4200 (about $8000 in 2007 dollars). Larry was most impressed with the M-510, describing it as "a very powerful amplifier with outstanding sonics across the board—power with delicacy."

For audiophiles of a certain age, the mere mention of NAD Electronics' original 3020 integrated amplifier (1980, designed by Erik Edvardsen), or Adcom's GFA-555 stereo power amplifier (1985, designed by Nelson Pass), conjures up happy memories of audio's last Golden Age—an idyllic time when working stiffs could luxuriate in the same audio arcadia as bankers and brokers. Since then, few, if any, audio components have achieved that level of iconic high value. Which caused me to wonder: What would it take, nowadays, to manufacture a genuinely high-value audiophile product: one that delivers exciting, satisfying sound at a price most audiophiles can afford?
