The new M12 is a modern front end to any system. All digital inputs types are supported as well as balanced and unbalanced analog inputs, all with precise analog gain control, seamlessly integrated into one product, your source controller.

The M12 builds upon the proven design of the M1 SE D/A converter so your digital sources are handled and converted in the best way. To that we add to it a pure dual mono analog signal path with high resolution analog gain and level control, controlling the output stage of the D/A converter in the analog domain with no loss of resolution and pass thru analog inputs for your analog sources. Like the M1, the M12 is a dual mono design with 3 power supplies and separate left and right analog power supplies and digital and analog processing.

Network Streaming

A new feature for the M12 is a network interface and media renderer. This allows the M12 to be seen as a DLNA device on an audio network and server as an audio device to play or stream to through a wired connection on your network. Now you can run wired data longer distances without loss in quality so your network server can go anywhere you choose.

DSD to new heights

Analog gain control has allowed us to take DSD playback to the ultimate level. The M12 features a pure analog DSD converter; any filtering and level is accomplished in the analog domain. When processed this way, no digital signal processing is done. Typically in most DACs the DSD is converted to a multi-bit sigma delta or PCM signal for filter processing. With the M12 we offer a pure DSD path and all post processing for noise filtering and level control are accomplished purely in the analog domain.

Analog level

All analog, precise, silent control with 90db of control range in one db steps, all remote controlled and programmable. The M12 digital controlled fully balanced dual mono resistor ladder is as good as level can be, and inserted at the source, at the output of the DAC’s I-V stage. This approach provides some of the best digital playback possible and analog control from the M12 balanced or unbalanced inputs.

Masterfully connected

Balanced and unbalanced analog inputs create the line amp stage for the M12. Fully balanced and a perfect match for the M28 power amps or the M15 stereo amp, the M12 provides true differential source control to drive any power amp.
