Audiolab M-One

Friday, September 02, 2016

We have seen it and heard it and the new Audiolab M-ONE is a cracking compact amplifier. Think Quad Vena in an Audiolab package!

More details to follow when they are available, but the M-ONE is a bluetooth equipped 60w per channel Class A/B Amplifier. It has Analogue inputs, Optical, Digital and 2 USB inputs. The USBs cover both Apple and PC/Laptop devices so you can pretty much connect any audio device to it. 

There's now support for DSD files, right up to DSD256 as well as support for hi-res audio up to 32-bit/384kHz over the USB A connection. The on-board DAC is the ESS9018 K2M, the "little brother" of the ESS9018 eight-channel DAC chip in the M-DAC+. 

As well as being at home powering stereo speakers, the M-ONE can also deliver sound to your ears via headphones, thanks to a built-in headphone amplifier - the same one as used in the M-DAC and M-DAC+.


Here's what Audiolab say: 

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 chassis.
 
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.
 
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.
 
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.
