Description:The audiolab M-ONE is a compact integrated amplifier and a fine addition to the M-DAC family. While harnessing our acclaimed DAC and amp tech in a single diminutive box, an array of analogue and digital connections, aptX Bluetooth and USB ensure a thrilling sonic experience with up to 384kHz resolution audio.An Amplifier For Modern Music LoversOutwardly, 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.Now DAC’s MagicThe 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.I’ve Got The PowerThe 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.Specifications:ModelM-ONEGeneral descriptionIntegrated Amplifier with BluetoothSampling Rate32-bit / 192kHz (Optical, Coaxial)32-bit / 384kHz (USB)2.8MHz (DSD64), 5.6MHz (DSD128), 11.2MHz (DSD256)Input sensitivity515mVInput impedance10KInputs1 x USB A for apple devices, 1 x USB B for computer,1 x COAX, 1 x OPT, 1 x Bluetooth, 2 x RCA ,1 x headphone12v TriggerYesPower Output (8 Ohms)2 x 40WPower Output (4 Ohms)2 x 60WFrequency response (-3dB)10-30kHzTotal harmonic distortion (THD)0.01%Signal-to-noise ratio (S/N)105dBOutputsSpeaker Terminal OutputsDimensions114mm x 247mm x 292mmNet weight5.5kg
This is a fair, buyer-friendly price rather than a bargain or an ambitious ask; at US$349, it sits essentially on the US$349 median and just above the US$350 75th percentile, so it reads as right at market for the current used pool. That makes it more of a buyer’s market by pricing than a seller’s one, with no meaningful premium baked in.
What makes it interesting is the Audiolab house sound: these integrated units are generally well liked for a clean, composed presentation and enough flexibility to anchor a compact serious system. If the unit is fully functional and cosmetically decent, the value is in getting a respected all-in-one amp at a sensible ask; I’d mainly want confirmation on included remote, power supply, and whether the controls have any scratchiness or display issues.

Audiolab emerged from the frustration of two Imperial College students, Philip Swift and Derek Scotland, who in 1983 founded the brand in Britain to deliver high-quality hi-fi without exorbitant prices or needless complexity. Their debut 8000A integrated amplifier swiftly became a benchmark, praised for its robust build, transparent sound, and minimalist design that prioritized musical purity over gimmicks. This origin story rooted Audiolab in a philosophy of accessible excellence, evolving from kitchen prototypes to a lineup of landmark components like the 8000S preamp, 8000T tuner, and 8000M monoblocs.
The brand focuses on core hi-fi categories, excelling in integrated and power amplifiers, preamplifiers, DACs, CD players, tuners, and phono stages, with forays into AV processors and multi-channel amps during its TAG McLaren era from 1997 to 2004. Since joining the International Audio Group in 2004, Audiolab has refined its no-nonsense aesthetic while expanding to modern streaming and digital sources, always emphasizing engineering that extracts maximum performance from any system.
Audiolab holds a solid mid-tier position in the hi-fi market, renowned among discerning buyers for exceptional value—delivering near-high-end sound quality at approachable prices. It appeals to purists seeking reliable, unadorned British engineering rather than boutique exotica or vintage collectibles, maintaining a loyal following for its enduring reputation in straightforward, music-first performance.
