M19 Reference SACD/CD Transport

The M19 is a simple CD and SACD compatible disk player.  It is a transport, meaning the M19 has no D/A converter and is designed to be used with an external DAC.  As such, the M19 has AES and SPDIF outputs as well as a proprietary I2S output designed to interface to our line of DAC products.  Care was taken to provide a very simple to use product for the task of playing your favorite disks.

Build Quality

The M19 is robustly constructed of milled and CNC machined aluminum sections, no typical bent metal chassis and top cover found on most products. All sections of the construction, the front and rear panels, the sides and even the bottom and top plates start out as solid blocks of aluminum which are precision machined to shape, with exact tolerances for a perfect fit.  

Front Panel Overview

The front panel has a large, simple, easy to read graphic display, an encoder for changing tracks adjusting and selecting settings, and dedicated function buttons. There is an IR receiver built in to the left side center of the display for using the M19 remote controller.

Rear Panel Overview

Looking at the rear you will find on to the left in the picture, the trigger in and out jacks, AES, SPDIF, and RJ 45 network connector for I2S.

SACD and DSD playback and the M19

When playing a SACD, and using the AES or SPDIF outputs, the DSD playback will be transmitted as DoP and Native format via the I2S..  The M19 does not employ and sample rate conversion or up-sampling of the data streams and passes the original sample rate to the DAC for conversion.   The only processing done is for creating the DoP format for DSD out the AES/SPDIF outputs..

I2S Output on the M19

The M19 has a proprietary implementation of I2S.  There is no “standard” for the use of I2S outside the confines of a product as its intended use is for interconnecting of PCBs inside of a product.  In our implantation, we use an RJ45 connector and it will mate to one of our DACs if it is fitted with the same RJ45 connector I2S option.  It should be noted that this interface is intended for use with our products and is not meant for general use with other products; the AES and SPDIF are there to support other manufacturer’s products as they are defined standard and will work with any product that supports these standards.
