M-ONE
The M-One is an integrated amplifier and DAC with Bluetooth. With technology
stemming from multi-award winning products, the M-ONE is a true high-fidelity DAC and
amplifier in one system.
On-board connections include 2 RCA inputs and Coaxial and Optical inputs. There are
also USB inputs on board – firstly a USB A that works for iOS device playback and
docking. The second USB B terminal, works for PC and Mac. Similarly to the M-DAC+,
the M-ONE USB B operates with 32-bit/384 kHz playback; this is a far higher
specification than that required by current hi-res music formats, ensuring this new,
premium-quality addition to the M-DAC family is fully equipped for future advances in
ultra-high-definition digital sound.
The USB input now also accepts DSD files (the digital audio system originally
developed for Super Audio CD), offering compatibility with DSD64, DSD128 and
DSD256. This is a significant addition, as DSD has an important role to play in the
developing high-resolution digital download scene.
The on-board DAC utilises the ESS9018 K2M DAC. This is surrounded by signature
Audiolab circuitry including a proprietary, discrete master clock to minimise jitter,
coupled with extensive time domain isolation. Using the highest quality components for
the output stage ensures that the audio signal, following conversion from the digital
domain to analogue, is of a high standard. Using audiophile grade class AB
amplification M-ONE generates up to 60 W at 4 Ohms; ample power for small to
medium hi-fi speakers.
The OLED display window is centrally positioned and flanked by two rotary controls,
one to adjust volume and the other to select settings – like all Audiolab products, the MOne evokes a simplistic yet modern styling with a focus on ease of use. Available in fine
textured aluminium finish (black and silver), the M-ONE will fit beautifully into any living
space.
QUAD Z-SERIES
Unlike conventional dome treble units, where the voice coil ‚motor‘ is attached
separately to the diaphragm, Z Series ribbon is both the diaphragm and the motor
system. The result is a unique combination of delicacy, smoothness and hear-through
performance that helps make music sing.
In the Z Series floorstanders this advanced ribbon unit is married to an equally high
performance midrange driver with a unique double-roll-surround especially designed to
control edge breakup and give equal transparency to the all important vocal range.
Both midrange and bass drivers feature Quad’s woven Kevlar cone geometry, now
matched by the double-roll-surround for the same smoothness and clarity offered by the
ribbon treble unit. The bass section, similar to the original Corner Ribbon, utilizes an
acoustic filter bass reflex system that maintains the natural and unforced reproduction
right down to the lowest frequencies of a symphony orchestra.
The skilfully hand veneered cabinets don’t need to be described as one look at the
images, here, will give you a taste of how the Z Series furniture quality woodwork will
look in your living room. Quad Z Series – beautiful performance and looks combined, for
‚The Closest Approach to the Original Sound‘.
VA-ONE
In principle the QUAD VA-One follows the legendary approach set by founder, Peter
Walker, to bring ‚The Closest Approach to the Original Sound‘ into your home by using
exemplary circuit design with high quality component selection and precision build
quality. What sets VA-One apart is its integration of classic valve amplification with the
ability to use a multitude of sources, both analogue and digital.
For connections you’re spoilt for choice – users can choose to play analogue devices
via the gold-plated RCA terminals or digital devices with playback up to 192 kHz via the
optical and coaxial inputs. There is also a 6.3 mm jack headphone output for discrete
use.
Furthering its digital connections, provisions for use of computers, tablet devices and
mobile phones have been made: The VA-One also has a USB B input for Mac/PC (with
playback of up to 192 kHz) and a wireless Bluetooth input. Using the aptX codec, even
via Bluetooth sound quality is not compromised, reproducing the full audio bandwidth in
exquisite detail.
Both analogue and decoded digital sources are fed to the integrated valve amplifier
which utilises an ECC83 high impedance triode as the preamplifier, feeding an ECC82
twin triode driver and phase splitter stage. The output stage uses 2 EL84 pentodes in
push-pull to deliver 15 W RMS per channel into nominal 6 Ohm loads (matching the
majority of modern loudspeakers). As well as providing the musically transparent and
immersive sound typical of classic valves, the performance is highly detailed without the
unwanted coloration that you would often associate with inferior valve amplification
thanks to the highly specified output transformers.
With a continued theme of convenience, a remote control is included for source select,
Bluetooth pairing and volume control – operating the large motorised potentiometer on
the front panel. Also on the front panel are robust source select and Bluetooth pairing
controls housed within a compact Lancaster Grey finished chassis – classically Quad in
styling.
The VA-One couples the elegance of valve topology with digital audio for an animated
performance, on every device.
WHARFEDALE DIAMOND SERIES
DIAMOND ACTIVE A1
For over 30 years, The Wharfedale Diamond Series has been the go-to speaker for
entry level, high-fidelity sound. Praised for articulated performance at an affordable
price, Diamond 200 series has won multiple awards, with „What Hi-Fi? Sound and
Vision“ commenting on its sound quality as „Agile, far-reaching dynamics; overflowing
with detail“ (Diamond 220 – March 2015).
With such a rich history of high performance combined with affordability, Wharfedale
proudly present the Diamond Active A1. The new wireless bookshelf speakers
incorporate everything music fans love about Diamond series into an easy to use
package, equipped to cater for a wealth of audio sources with an innovative approach to
wireless technology.
A HUB FOR YOUR MUSIC
Unlike other wireless and active speakers where controls and inputs are often placed
awkwardly on the back panel, Wharfedale engineers have developed a unique hub,
which works as the central console for your music.
The Diamond Hub features optical, coaxial and RCA inputs on the rear panel with an
additional Bluetooth aptX connection for wireless integration of laptops, smart phones
and tablet devices. It’s controlled gracefully via the touch sensitive display, or for even
more convenience you can use the included remote.
Once connected to your source, the Hub works independently from the speakers using
the 5.2 GHz/5.8 GHz wireless frequency band. Place it on your TV stand, desktop, or
wherever you want, without the worry of speaker placement and trailing wires inbetween the units.
HIGH-FIDELITY OVER WIRELESS
To ensure the same high standard of sound as conventional wired hi-fi components,
Wharfedale engineers have utilised an advanced wireless module, operating on the
5.2 GHz and 5.8 GHz frequency band. While avoiding the often crowded 2.4 GHz band,
the Diamond Active system is able to switch intelligently between bands, guaranteeing
minimal interference, wherever your speakers may be placed.
Additionally, the DAC is built around a high performance 24 bit chipset delivering a CDlike quality from all devices.
ADDITIONAL CONTROL FOR OPTIMAL PLACEMENT
While the Hub makes day-to-day use of the system a breeze, additional room settings
are available on the rear panel of the speaker. A +/-6 dB bass control works to adjust
the system for personal preference and for optimum room placement, for instance
placing the speakers near a wall. Engineers have also added a mono mode, which is
ideal for when unconventional speaker placements are used – you can place the
speakers anywhere in your living area and still enjoy a thrilling sound.
A REAL DIAMOND
The speakers use the same drivers as seen in the award-winning Diamond 220.
Wharfedale’s signature woven Kevlar cone incorporates semi-elliptical ‚break-up‘ areas
which smooth the response throughout the audible range. The treble unit uses an
advanced ferrite magnet system and carefully constructed waveguide around the fabric
dome for optimal dispersion.
While this is identical as seen in the Diamond 220, the cabinet has been tailored for the
convenience-themed technology within. A rear-tuned bass port system means
engineers were able to reduce the cabinet volume – more akin to those seeking an allin-one easy to use system.
Cabinet edges have been stylishly rounded and wrapped in luxurious black leatherette
with a high-gloss front baffle available in black or white finish options.
WHARFEDALE REVA SERIES
Reva is the latest range of audiophile standard speakers from Wharfedale, the most
famous name in British loudspeakers.
Reva is designed from the ground up to offer state-of-the-art tonal accuracy and musical
detail. Within Reva’s fashionably curved panels are special layers of wood composites,
which reduce the sonic character of the cabinets to a level where it cannot be heard
below the sound from the drive units.
Research and development was heavily focused on developing this combination of
materials which is a new, premium version of Wharfedale’s composite layer as found in
the award winning Diamond 200 series.
While incorporating a premium cabinet style and structure, Reva Series also utilises
signature Wharfedale technology with a slot-loaded port design. In Reva the internal
high pressure in the interior cabinet port is balanced by the pressure loading of a slot
formed between the cabinet and plinth. This not only reduces the distortion that is
typically found in bass reflex ported systems but also increases its efficiency.
The result is that Reva speakers are easier to position in the room for a deep, powerful
but controlled bass performance that maintains the accuracy necessary for transient
impact and articulation.
Musical accuracy and articulation is also carried through to the midrange by
bass/midrange driver cones that incorporate a bi-directional weave of Kevlar that is
naturally self-damping to reduce and distribute resonances to virtually negligible levels.
These cones are mounted in a special alloy, cast chassis to ensure dynamic rigidity. A
fixed, profiled phase plug ensures a smooth acoustic roll-off to enhance integration with
the treble unit.
A new, fine weave textile dome, with critically damped coating, has been chosen for the
25 mm treble unit, powered by a neodymium magnet fitted with a finned heatsink to
reduce dynamic compression. This unit offers excellent bandwidth, with a smooth
response from 2 kHz to above 20 kHz, and is mounted on a subtly dished waveguide
that enhances dispersion.
These advanced drivers are combined, acoustically, with a precision crossover utilizing
Linkwitz-Riley slopes calculated using Wharfedale’s advanced Computer Aided
Optimization techniques. The final crossovers are the result of hundreds of hours of fine
tuning using a variety of music to ensure that Reva speakers meet the requirements of
audiophiles the world over.
Finally each Reva speaker is hand-finished by Wharfedale’s cabinet craftsmen with
multiple layers of polished lacquer to achieve a high gloss finish that complements any
interior design, available in Piano Black, Piano White and Piano Deep Rosewood. This
combination of beautiful finish and sonic excellence will ensure that the owner will be
proud to own Reva – truly a work of art.
