The Audiolab M-ONE is a compact integrated amplifier - the
latest addition to the M-DAC family. While harnessing our acclaimed DAC and amp
tech in a single diminutive box, an array of connections, both analogue and
digital, aptX Bluetooth and USB ensure a thrilling sonic experience with up to
384kHz resolution audio.
An Amplifier For Modern Music Lovers
Outwardly, the M-ONE is almost identical to the M-DAC+,
Audiolab’s flagship DAC component. It sports the same compact aluminium case,
small enough to sit unobtrusively on a desk, table or shelf, with the same
central OLED display and elegant dual rotary control scheme. But while
standalone DACs require a separate power amp to drive a pair of speakers, the M-ONE
packs stereo power amplification of suitably high quality, plus preamp
facilities for analogue sources as well as digital, into its diminutive
Now DAC’s magic
The M-ONE’s DAC section is equipped to process PCM audio
data up to 32-bit/384kHz via USB, ensuring the M-ONE is primed to take full
advantage of high-resolution digital sound both now and in the future. The USB
input also supports DSD files (the digital audio system originally developed
for Super Audio CD), offering compatibility with DSD64, DSD128 and DSD256 – a
significant inclusion, as DSD has an important role to play in the developing
hi-res audio scene.
Filters For All Music Sources
To get the most out of the Audiolab M-ONE’s advanced sound
processing, included are a range of user-selectable filters to fine-tune sound
from digital sources according to taste. A selection of three PCM filters and
four DSD offer sonic tailoring options to cater the varying quality of audio
delivered by different digital download file types and sources.
I’ve Got The Power
The preamp section mixes minimalist design with high-quality
components, ensuring a short, direct signal path to maintain sonic purity.
Volume is digitally controlled in the analogue domain, outputting directly to
the Class AB power amplifier, which delivers an output of 40W per channel into
8 ohms – plenty of power to drive efficient modern speakers to room-filling volume
levels without a hint of strain.
A low-noise linear power supply benefits all
circuits from the DAC to the power amp, incorporating a shielded,
precision-wound toroidal transformer and multiple power supply sections to keep
crossover interference to a minimum. This uncompromised circuit design enables
an open and amply scaled soundstage brimming with crisp detail and swift,
precisely defined musical transients – when used with speakers of suitable
quality, the M-ONE’s performance belies its diminutive size.
In addition to the main power amp stage, the M-ONE shares the same high-quality
headphone amp featured in the M-DAC and M-DAC+, ensuring it’s just as capable
with headphones as it is when powering speakers.
