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.

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 C 399 delivers great performance, impressive features and flexibility, and high value in a modest, yet handsome package.

While waiting on the arrival of NAD's C 399 integrated amplifier for review, I checked it out on the company's website. What I saw there was a minimally adorned exemplar of the black-box design school, with steel chassis panels of ordinary fabrication and a small display showing mostly monochrome text. Yawn. Well, a funny thing happened when the C 399 finally arrived, and I unboxed it. I took a shine to its no-frills, understatedly handsome looks. Sure, there are more striking-looking components out there with more robust build quality, but they'll cost you.

THE VERDICT
Cambridge Audio’s feature-packed wireless network streamer/integrated amplifier offers substantial power and generally excellent performance at a reasonable price.

Now headquartered in London, English audio product manufacturer Cambridge Audio was founded in 1968 in the university city of the same name. The company's initial product was the walnut-trimmed 20 watts-per-channel (Wpc) P40 integrated amplifier. (Notably, the P40 was the first consumer audio amp to contain a toroidal transformer, a now de rigueur feature in high-end audio.)

THE VERDICT
Linn's all-in-one wireless streamer/amplifier/DAC offers impressive sound, sleek looks, and plentiful connectivity options.

According to the corporate lore of Scottish audio manufacturer Linn, in 1973 a newly married engineer named Ivor Tiefenbrun went shopping at his wife's direction to buy home furnishings. To his wife's chagrin, the story goes, he instead returned with a stereo system. After setting it up, Ivor was disappointed with the sound, but soon discovered that moving the turntable from his listening room into an adjoining room improved the system's performance since the speakers' output no longer interacted with the turntable and distorted the audio signal.

THE VERDICT
An affordable integrated amplifier-DAC with substantial power, high-quality conversion, flexible inputs and outputs, and full-function remote. Bravo.

I like simple. Simple is good. Simple works. Simple makes my job easier and helps me sleep at night.

Parasound, a Bay Area maker with a half-century of success walking the parapet between high end audiophilia and value-engineering design, apparently concurs. The company's new NewClassic 200 Integrated is, as you might well guess, an integrated amplifier, with a high-quality onboard digital-to-analog converter section. The 200 Integrated was in fact derived by the simple expedient of sliding a class-D stereo power amp sourced from Danish class-D amp-module stalwart Pascal Audio into its otherwise-identical preamp stablemate. This slim, two-channel module delivers a claimed 110 watts per channel into either 4-ohm or 8-ohm loads with typical class-D efficiency, pulling only a modest 50 watts from the wall.
