SMSL M400 DAC bilanciato AK4499 XMOS XU216 MQA 32 bit 768 kHz DSD512

The SMSL M400 is a DAC with balanced and single-ended outputs that uses very high fidelity components: AKM AK4499 DAC chip, XMOS U216 USB interface. It supports MQA formats.

DAC AK4499

The M400 uses a high performance AK4499 DAC chip. This is currently the best performing conversion chip built by AKM, allowing the M400 to achieve an impressive 131dB SNR with a THD + N of -124dB. Thanks to this conversion chip, the M400 supports high sample rates and allows you to enjoy the most accurate reproduction possible for your ultra-high-resolution audio files. The M400 is capable of playing PCM files up to 32-bit 768kHz and Native DSD files up to DSD512.

MQA support

MQA for Master Quality Authenticated is an award-winning British technology for restoring the sound of the original recording. The MQA Master file is authenticated by the artists, producers or rights holders. These files are small enough to be streamed or downloaded. The M500 includes an MQA decoder to play these files in order to provide the best possible audio quality.

Complete connectivity

As for the connections, the SMSL M400 is extremely well equipped, with an optical SPDIF input, a coaxial SPDIF input, a USB-B input working with an excellent XMOS U216 interface, an I2S input via HDMI respecting the LVDS standard.
The M400 can also receive bluetooth audio streams and supports the best audio protocols available today: UAT, LDAC, apt-X HD, SBC, AAC, for wireless transmission up to 192kHz - 24bit.
The device has a balanced stereo output on 3-pole XLR connectors and a single-ended stereo output on RCA connectors.

XMOS XU216 USB interface

The USB input of the M500 is associated with a 32-bit XMOS XU216 XMOS interface, with custom driver. This ensures rich and transparent reproduction while supporting high sample rates.

Clock Accusilicon

The M400's digital stage uses ultra-high-precision, ultra-low-noise Accusilicon clocks to provide the best audio performance.
These crystal oscillators with extremely low phase noise (<90dBc @ 10Hz) are generally intended for professional recording devices. They offer a singularly low jitter rate measured at <2ps on the 10Hz-1MHz band and <0.08ps on the 12-80MHz band.

Filters

The SMSL M500 also includes 7 digital filters for PCM signals, allowing you to tailor the playback to your listening needs.

Display and housing

The SMSL M500 is equipped with a beautiful bright display on the front panel, which allows it to view all information about the current playback. This includes the volume level, active input, stream and file type, as well as the sample rate of the read file. This screen is protected by a tempered glass plate.
The components are hidden under a beautiful and sturdy CNC machined anodized aluminum housing.
The unit is also equipped with an IR remote control for easy remote control.
