Plus
Honest audiophile-grade sound
Free app delivers a good selection of streaming services
Proprietary two-channel room/speaker-correction EQ works well
Above average FM tuner included
Minus
Amplifier power may not be adequate for all speakers, larger rooms
No subwoofer output; no fixed-level line input for easy multi-channel integration; no 12V trigger
Lacks the touchscreen interface found on several competitors

THE VERDICT
An all-in-one streamer/amplifier that promises and delivers genuinely high-end sound, though with relatively modest amplifier power.

The twentieth century had its Roaring Twenties; welcome to the twenty-first’s Streaming Twenties.

Integrated amplifiers equipped with on-board streaming facilities and software, and the requisite digital-to-analog conversion hardware, have taken the place that the stereo receiver once held, back in the 1960’s, ’70’s, and ’80’s.

Gorgeous matching components
Streamlined integration
Excellent sound quality
Minus
Identical remotes
App lacks direct access to Tidal and Spotify

THE VERDICT
Combining a streaming media player and amplifier eliminates all excuses to use anything else to play music. You can add the speakers you prefer for the music you enjoy with seamless access to Tidal, Spotify, UPnP, and a USB drive powered by a 100 Wpc amplifier. What a winning combination!

Come on and admit it. Most of the time, when you stream your favorite playlist from Spotify or Tidal, you just toss it to the nearest little Bluetooth speaker you have. Or heaven forbid, just listen to it on your phone. Oh, the humanity.

While getting access to infinitely massive libraries of streaming music has become amazingly easy, listening to that music on a high-quality system still seems to be elusive. However, pairing the new Arcam A25 integrated amplifier with the also-new Arcam ST5 streaming media receiver makes it effortless to get your music from the cloud out to your oft-neglected stereo speakers.

Superb sonic quality, savory bass, audiophile-grade imaging
Dirac Live room correction
Streaming (and multiroom expandability)
NAD’s BluOS ecosystem and Bluesound iOS/Android apps
Front-panel meters are retro-licious
Minus
Full-bandwidth Dirac requires paid upgrade
Only one analog line input
No pass-thru for multichannel

THE VERDICT
A “simple” stereo integrated that commemorates NAD’s original designs but conceals considerable technological depths, including Dirac Live room correction, wired/wireless networking with app-directed streaming, and Class D power.

I love vintage. Of my four motorcycles, which included a beloved 1958 Triumph T20 Tiger Cub, the 1989 Honda NT650 is the newest. Of my dozen or so guitars, my 1964 Strat and 1966 D-18 are the undisputed stars, while a 1965 Fender Deluxe Reverb guitar amp is the apple of my ear. I’ll never part with any of these; just pile them upon my bier when the time comes. But vintage hi-fi? Vintage hi-fi?

THE VERDICT
The Marantz Model 40n is a thoroughly modern music streaming machine that sounds great and delivers a robust set of features without losing sight of the brand’s storied past.

I attended a launch event for the Marantz Model 40n a few months ago and marveled at just how far the iconic brand has come since founder Saul Marantz took his first steps as an audio pioneer way back in 1945. In true hobbyist fashion, he modified his car radio so he could listen to it at home and, once it was up and running there, continued tinkering with it to improve its performance.

THE VERDICT
Rotel’s affordable A14MKII integrated is light on features but heavy on performance. A great option for listeners who want to keep their audio system simple.

Back in fall 2021 Sound & Vision reviewed Rotel's RA-1572MKII integrated amplifier, an upgraded version of the company's popular RA-1572. Well, at Rotel the upgrades keep coming fast and furious: Just a few months later, word dropped that the same treatment was coming to products at more affordable price points, with the company's A12 and A14 integrated amps getting bumped up to MKII status.

Lacks Wi-Fi, AirPlay wireless streaming

THE VERDICT
Rotel's MKII version of its RA-1572 integrated amp delivers impressive power and transparent sound with digital and analog sources but lacks the comprehensive streaming features found on similar designs from other manufacturers.

True story. My very first hi-fi system featured a Rotel integrated amplifier—if memory serves, a model RA-20 of some 20 watts per channel. I bought it brand new for around $60 from K&L Sound in Watertown, Massachusetts, with money saved from my after-school job building shelves, sweeping floors, and punching holes in sheet- metal panels that would become the very first ARP synthesizers. (The late Alan R. Pearlman was my next-door neighbor and a lovely, kind, brilliant guy.)

THE VERDICT
The M33 combines state-of-the- art sound, power, and broad functionality in an elegantly conceived package.

Boy, has NAD come a long way. Back in 1978, the Canadian/ American/Euro multinational's first product was an unassuming but great-sounding little 20-watt integrated amplifier in a plain gray sheetmetal box, with controls that had all the sophisticated feel of a Kenner Easy-Bake Oven.
