M-DAC+ Digital-to-analogue converter

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.

Technology
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.

Ajustable sound for all sources and tastes
As digital audio technology has progressed, the importance of the characteristics of reconstruction digital filters has become more appreciated. Like the classic M-DAC, the M-DAC+ features user-selectable filters for optimal listening and measurement modes, in addition to more conventional types for easy comparison. These filter settings allow the user to tune performance to suit his or her preference, depending on system configuration, digital file quality and musical taste. The M-DAC+ inherits seven filter settings from the M-DAC for PCM files and adds four more for DSD playback, allowing the user to optimise the noise floor to suit the performance of the source file and the bandwidth of associated equipment such as amps and speakers.

Enhanced Sonic Performance
Another important change relates to the power supply, which has been upgraded and is now incorporated within the M-DAC+’s chassis (hence its slightly taller and deeper case compared to the classic M-DAC). A precision-wound toroidal transformer uses multiple windings to feed separate analogue and digital rectification stages. From there, multiple power supply sections feed the necessary voltages to each area of the DAC, keeping any crossover interference to a minimum. The result is the highest performance power supply Audiolab engineers have yet specified for a DAC, and its contribution to the M-DAC+’s enhanced sonic performance is significant.
