AK4497 DAC & High-end components
The M300 is equipped with an AK4497EQ high-end DAC chip from AKM. The latter supports high sampling rates, in PCM up to 32bit 768kHz and in DSD up to DSD512. In addition, the chip uses the proprietary Velvet Sound architecture allowing it to provide a high SNR (128dB) and very low distortion (THD+N -116dB) for neutral and accurate reproduction, with a beautiful sound image.
This chip is combined with many quality components such as a second-generation XMOS USB interface, two ultra-low phase noise Japanese NDK clocks to significantly limit jitter on 44.1kHz / 48kHz and multiple frequencies, and finally a series of resistors and capacitors specially designed for audio use.
Design, Screen & Connectivity
All components are integrated into a beautiful CNC machined Aluminium housing, both robust and allowing to limit interference that could degrade the audio signal. The front panel is covered with a tempered glass plate of the most beautiful effect and a 1.54" IPS screen, allowing you to display all the information related to the reading of your files (input, filter, sampling rate, read format...). The control is done simply with the two buttons on the front panel, allowing you to turn the device on/off, select an input, change the display color or choose an audio filter.
The back of the device contains all the connections. Toslink Optics, Micro USB (XMOS) and Coaxial are at the input. On the output side, the M300 offers either symmetrical XLR or asymmetrical RCA.
