The M51 includes many 'firsts' for the DAC product category: first to support HDMI, first to support USB Audio Class 2 with support for 192kHz, the first to use digital error correction, and the first 35 bit architecture to be found in a DAC.
The incredible precision of the M51's processing engine gives music a vibrancy and transient accuracy that must be heard to be appreciated. The conversion process from PCM to PWM completely eliminates any jitter present on the incoming signal; again offering state-of-the-art performance in this most important parameter. Because of the very high clock speed and mathematical precision of our reconstruction filters, the resulting audio signal is totally free of digital artifacts like ringing. A Pure Class A analog stage with very low output impedance provides the perfect interface to your favourite Amplifier. Both balanced and single-ended outputs are available.
While the M51 includes the industry standard SPDIF inputs, in AES/EBU, Optical and Coaxial inputs, it also includes the latest USB technology. Called USB Audio Class 2, it supports sample rates of 192kHz releasing the previous limitation of USB at 96kHz. Both Host and Device USB ports are included allowing direct connection of a PC or MAC in addition to the connection of a USB flash or Hard Disc memory device. The M51 offers 2 HDMI inputs and 1 output with video pass through.
M51 is a fully functional digital preamp with seven digital inputs and one of the world's best volume controls. As a 'preamp' it is totally noise and distortion free because all switching and volume control is done in the digital domain. There are no analogue circuits save for the Class A buffer at the output of the DAC.
