Identical remotes

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.

THE VERDICT
Cambridge Audio’s commemorative Edge A combines top-shelf sound with gorgeous industrial design. The price may be a cut above average, but the Edge A is no average integrated amp.

Do you really need a $5,000, 54-pound, two-channel integrated amplifier? Yes, of course you do. Especially if that integrated amplifier is the new Edge A from Cambridge Audio, a British firm with a long record of seriousness about sound reproduction. Cambridge’s gear has always struck me as a rigorously high-end/high-value proposition, but the Edge A looks, tastes, and smells more like a no-holds- barred statement design, the kind we’re more likely to expect from a company whose bottom line is that they don’t give a fig for the bottom line.

THE VERDICT
Elac’s Element EA101EQ-G amp/DAC nails the sweet spot of price, performance, and worthwhile features with surprisingly audiophile sound and the added value of auto-EQ and app-enabled subwoofer crossover/blending.

It’s an amplifier. It’s a USB DAC. It’s a room/subwoofer equalizer. It’s a headphone amp. It’s an app-enabled Bluetooth receiver. It’s all of these, and it’s only $699—and it’s from the revived German brand Elac, whose latest Andrew Jones–designed loudspeakers have won acclaim in these pages and elsewhere. Ultimately, Elac’s Element EA101EQ-G may be best characterized as what the stereo receiver is morphing into for the 21st century.

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
The Micromega M-150 is a pricey, somewhat limited, but fine-sounding integrated amp with a super-slim form factor and surprising power.

Nominally, French firm Micromega would seem a deeply conflicted organization. Is it micro, or is it mega? We may never know. (For the record, “Micomégas” is an 18th-century, ur-science-fiction novella by that most French of Enlightenment figures, Voltaire.)

Either way, the south-of-Paris firm has an established record of filling niches in the ever-shifting digital-audiophile world, beginning with several notable high-end CD players. Today, like most such manufacturers, Micromega is redefining itself for the post-physical media age: Witness its latest M-One duo of streaming- capable, digital-input integrated amplifiers—streamplifiers, as I like to call them.

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.

PRICE $749 (was $699 at time of review)

THE VERDICT
The D 3045 is a surprisingly powerful compact integrated amplifier with an eminently capable onboard DAC that's equally at home on the desktop or component rack.

Five years ago, when I examined NAD's $399 D 3020, the progenitor of the D 3045 before us here, I liked it—a lot. The D 3020 was among the first of what I've come to call DAC-lifiers: small-ish integrated amps with onboard digital-to-analog facilities intended for audio-streaming or computer sources and projecting at least some level of audiophile sophistication.
