Integrated Amp Reviews

AT A GLANCE
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.

Power to push most speakers with clarity at all sound levels.
Wi-Fi connection supports up to 192kHz/24- bit high-resolution audio.
Plays from a wide variety of streaming and physical music sources.
Clean design with easy-to-read front display.

Minus
The DTS Play-Fi app is clunky, buggy, and hard to use.
There is no equalizer to make sound adjustments.

THE VERDICT
With the Prime Wireless Pro SoundBase, streaming music has become a sit-down-and-listen experience rather than just background music. It has excellent sound quality for a reasonable price. It’s a great addition to include quality stereo music streaming, even if you already have a sound system.

For anyone who has been waiting for streaming music to be a high-quality sit-and-listen experience, the SVS Prime Wireless Pro SoundBase streaming integrated amp fits the bill. It’s the second-generation S VS wireless smart integrated amplifier.

Not only can it play just about any high-resolution audio file you send to it, but this 300-watt class D amplifier powers your speakers easily for outstanding sound. Connect it to standard speakers, and it becomes a DTS Play-Fi zone with reference sound (i.e. uncompressed) quality that can stream from numerous music services like Tidal, Deezer, Qobuz, Amazon Music, and others.

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.

Surprisingly powerful amp

limited feature set compared to competition
Streaming options limited to Bluetooth wireless and direct computer-to-USB input

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.

Network connection doesn't support audio
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.

THE VERDICT
With its extremely solid build quality, future-proof feature set, and excellent sound, Hegel's H390 could be the last integrated amp you'll ever need.

Hegel Music Systems is a Norwegian audio electronics manufacturer that has been slowly and steadily making a mark on the high-end audio world since it started out in the early 1990s. One thing that distinguishes Hegel from other audio companies is its portfolio of proprietary technologies that were developed in-house by founder and chief designer Bent Holter.
