December 2014

Five-star rating for the Airstream A100

Monitor Audio's Airstream A100 has been pitted against some of its peers in the latest What Hi-Fi? Magazine test on amplifiers. The A100 was reviewed back in August of this year, and it's great to see that the A100 is still leaving a lasting impression. Right from the start the A100 impresses with its stylish design and composed, insightful sound:

"The spread of sound is wonderfully open and wide - far wider than with any rival. And in that spacious soundfield the music is crisp and clear. The level of detail is stunning, and it conveys a tune - with a great deal of composure and refinement."

The review concludes for our AirPlay® Amplifier with the following:

"...The A100's smart, sleek design is gorgeous, and its spacious, insightful sound will garner many fans."

A100 adds a 'Red Dot' to its Five-Star Design

Having wowed the team at ‘What Hi-Fi?’ the A100 is now recognised internationally as a supreme example of design engineering by winning a coveted ‘Red Dot’ award. One of a total of 4,815 entries from 53 countries, the compact, innovative and oh-so-connected A100 network-ready amplifier impressed the 40-strong Red Dot jury of experts with an exclusive blend of technology and style. Monitor Audio’s A100 received the “Red Dot Award: Product Design 2014” at a gala ceremony held at Essen, Germany on 7 July 2014. It is now on display during a four-week special exhibition at the city’s Red Dot Design Museum until 3rd August.

A100: Trusted Reviews Recommended!

Reviewer Danny Phillips has tested our A100 AirPlay® Amplifier in both music streaming and home cinema applications.

"If you’re using the A100 with an iOS device, AirPlay setup is a piece of cake thanks to Wi-Fi sharing. Just connect the device to the USB port, press the Wi-Fi button on the back of the A100 and a dialogue box appears on the device asking if you want to share Wi-Fi settings. Job done."

"...effects are dispatched with real bite but the A100’s remarkable composure means they never sound harsh or resonant, which keeps the sound listenable even at high volumes – and it certainly goes loud when you need it to. God help your neighbours."

"Another of the A100’s assets is its terrific treble reproduction. Crisp, sparkling highs breathe life into every scene and keep dullness from the door, plus it brings out subtle textures that more heavy-handed amps overlook. But it doesn’t overdo it – there’s a nice balance right across the spectrum."

On awarding the A100 a Trusted Reviews Recommended title, Danny concludes with the following:

"We love its radical, eye-catching design, which sets it apart from virtually every other sound system on the market, while its luxurious build and generous connectivity options (including AirPlay) are other plus points. But we’re most impressed by the A100’s sumptuous sound quality, which is powerful but imbued with the sort of refinement and composure we’ve come to expect from other Monitor Audio products."

Hi-Fi Choice Recommended award

Monitor Audio's very own Airstream A100 has received further praise for it's versatility and ability. With both DLNA and AirPlay® streaming delivering class leading audio quality and earning an impressive Hi-Fi Choice Recommended award in the latest review.

Adrian Justins, technology feature writer for Hi-Fi Choice examines our small but mighty amplifier:

"DLNA streaming of hi-res files is the cream on the cake, offering incredible scale and depth to recordings such as a 24/192 download of Mozart’s Violin Concerto No.4 in D Major."

"Results with AirPlay are no less impressive, Silent Shout by The Knife proves that bass extension is particularly impressive, underpinning the mid-range and high notes of the synth to perfection.'

Five-star rating for the Airstream A100

Monitor Audio's first ever amplifier, the Airstream A100 takes centre stage in a What Hi-Fi? Magazine First Test! Right from the start the A100 impresses with sheer performance and versatility:

"This Monitor Audio delivers an unusually wide soundstage and populates it with a decent amount of precision. We're impressed by its refinement too. This quality isn't bought at the expense of treble bite, with the highs being delivered with a good amount of sparkle. The overall tonal balance is nicely even, with no part of the frequency range dominating."

The review concludes with a clear verdict for our AirPlay® Amplifier:

"...we feel the A100 deserves a five-star rating. It's a brave product that performs well and can be used in situations where conventional alternatives wouldnt even get a look in."
