The new M-DAC+ is a high-performance, multi-purpose audio DAC (Digital-to-Analogue Converter) for home use, designed to sit on a desk or table or integrate into a hi-fi system. It incorporates a highly specified, audiophile-quality digital preamplifier and Class A output stage for connection to a power amp and speakers (the output can be fixed for those who wish to use an existing preamp or integrated amp), in addition to a high-quality output for headphone use.
Redefining a Classic
The new M-DAC+ is based firmly on the classic M-DAC, with carefully targeted improvements in key areas – a logical move, given the original model’s sustained popularity over the last four years. The M-DAC built a peerless reputation with press and public alike since its launch in the autumn of 2011, scooping multiple Product of the Year Awards from the likes of What Hi-Fi?, Hi-Fi Choice, and EISA to make it arguably the most critically acclaimed DAC component ever made. “The Audiolab M-DAC+ gets an awful lot right – so much, in fact, it comfortably justifies its ‘+’ designation”. ~ What Hi-Fi? Sound and Vision, June 2016.
The Finest DAC Circuitry
Like the M-DAC, the M-DAC+ incorporates the ES9018 Sabre Reference 32-bit DAC chipset, still widely regarded as the finest available. This is surrounded by exceptionally well-specified circuitry that puts other similarly priced DACs to shame, including a proprietary, discrete master clock to minimize jitter, coupled with extensive time domain isolation. A JFET Class A output stage ensures that the audio signal, following conversion from the digital domain to analog, is of the highest quality.
High Performance with DSD
Under the hood lie a number of performance-related enhancements. The M-DAC+ now processes audio data up to 32-bit/384kHz via USB; 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.
