July 2015

Radius 90 (With Airstream A100)

A great review from the July 2015 issue of Wifihifi, which discusses the high performance sound from the R90 and A100 system...

"...sounded warm and full, with a lovely texture in the strings."

"Rava's trumpet had delicious bite without being overbearing, and Stefano' Bollani's masterful piano work was beautifully delineated."

"Larry Grenadier's double bass sounded surprisingly satisfying."

"...this is a very enjoyable system, equally satisfying when listening up close, or when sitting back and listening out loud in a small to medium-sized room."

Wireless Audio Looks To Be In Good Shape

"The result is a lively and entertaining performance that allows us to sit back and enjoy the likes of Johnny Cash's 'Solitary Man'. There's a good sense of detail and energy, with Cash's gravely vocals coming through with a pleasing dose of emotion."

"The A100 may look like a style-based product but its capable of proper hi-fi sound too."

"We start off with Orff's 'Carmina Burana' from our reference Naim NDS streamer and are impressed with this Monitor Audio's punch. It delivers large-scale dynamics with a surprising degree of composure. There's no shortage of volume either."

"This Monitor Audio delivers an unusually wide soundstage and populates it with a decent amount of precision. We're impressed by its refinement too."

"The overall tonal balance is nicely even, with no part of the frequency range dominating."

"We like the A100's bass weight and grip, as well as its ability to keep the song's coarse signature in check."

"We listen to a range of music from Beethoven's 'Moonlight Sonata' to Kanye West's New Slaves and the Monitor Audio acquits itself with honour. It sounds insightful and composed, with enough in the way of drive and dynamics to satisfy."

"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 wouldn't even get a look-in. For that alone it deserves plenty of credit."

"Awesome sonics and stunning design mean Monitor Audio's first amp will be more than just a head turner."

"Starting with the analogue input connected to a CD drive I am instantly enamoured by the A100's smoothness, detail and staging."

"The finger clicking and bass plucking at the start of Diana Krall's My Love Is is quite sumptuous and the vocals have a mesmerising quality that fills my listening room with ease."

"What strikes me is not just the amazing clarity that a Class A/B amp offers, but the sense of airiness and balance throughout the dynamic range."

"The King's Singers' version of Paul Simon's The Boxer is equally engaging with spine-tingling harmonies that really have to be heard to be believed."

"The vocals at the start of Chris Jones' Darlin' Cory are hauntingly engaging, while the guitar strums with refinement and gusto."

"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."

"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."

"Some audio products blow you away with detail; others lull you into a relaxing stupor with a smooth, sultry sound. Monitor Audio’s little Airstream A100 struck a fine balance, confidently striding precisely between these two camps."

"I was smitten by its sound"

"...at once rich yet detailed, smooth but with a hint of sparkle, and surprisingly neutral."

"I was worried that this inexpensive, flyweight box, outputting only 50Wpc, might not be able to drive my big floorstanders well enough to produce the bass depth and control needed to properly energize my room. I was floored when it managed to do both."

"...the A100 grabbed the 8” woofers of my 90dB-efficient KEFs and forced them to dig deep. In this regard, the A100 was ear-opening."

"The midrange was beautifully weighted, neither forward nor recessed, and the Monitor’s built-in Cirrus DAC did an impressive job of unraveling low-level detail."

"Regina Spektor’s lithe vocals in “Fidelity,” from her Begin to Hope (256kbps MP3, Sire), were spry and clean, with very little of the haze and muddle that so often plague inexpensive all-in-one designs. On the contrary, Spektor’s voice was portrayed on the soundstage with reasonable precision and surprising clarity."

"...it was far more articulate through the mids than I ever would have expected."

"That the Monitor not only does nothing wrong, but an awful lot right, is a real achievement."

"I could listen to singer-songwriters for weeks at a time through the A100 and it would continue to command my rapt attention."

"With analog, digital, and wireless connectivity, an accomplished class-AB amplifier -- something its competitors can’t boast -- and sound quality that reaches well past its $499 price, it comes highly, highly recommended. $500 never sounded so good."

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."

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:

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."

  • New 4” C-CAM® bass driver - Radius features all new bass drivers with concave cone profiles, introduced by our top-of-the-range Platinum speakers and applied subsequently to Gold GX.  Extensive research and FEA modelling have allowed us to perfect the relationship between the new radiating diaphragm and its motor design, introducing larger motor sizes and voice coils for increased excursion, higher power capability and reduced distortion.
  • New C-CAM gold dome tweeter - optimised to deliver the finest and widest performance within the compact Radius cabinets. It benefits from a more efficient rear-venting design, releasing air trapped and compressed at the back of the tweeter dome, and guiding it around the drive assembly to a rear-loading chamber.
  • HiVe®II port design - Straight from Platinum’s design blueprint, the HiVe reflex port makes its Radius debut. It’s shaped to have the same effect on airflow as a gun-barrel on a bullet. Rifled grooves inside the port help to accelerate the flow and reduce turbulence, so air moves in and out of the port more efficiently, for a faster more dynamic bass response.
  • Single through-bolt driver fixing provides mechanical de-coupling and enhanced mid-band clarity and resolution. The through-bolts also act as rigid cross bracing to give a very solid non-resonant cabinet.
  • Single point ¼”x20TPI wall fixing. Use the optional Monitor Audio speaker mount or any standard wall bracket
  • Optional floor-stand with internal (pre-wired) cable management system.

  • New C-CAM® gold dome tweeter design with damped rear chamber and innovative dome venting technique for improved clarity and wider operating bandwidth.
  • 6” bass and 6” bass/mid-range drivers with concave ‘dished’ C-CAM cone profile for better damping and improved mid-range clarity.
  • Two and a half way configuration with differentially tuned acoustic system for higher efficiency and  improved low frequency extension.
  • RST® cone profile, for improved diaphragm rigidity and reduced distortion.
  • New cast polymer bass chassis design for better rigidity and reduced reflections.
  • HiVe®II port technology delivers smoother airflow for better transient response and tighter bass.
