Know before you buy
Yes, the M8x features full hardware MQA decoding across its USB and all S/PDIF inputs, ensuring high-quality playback for MQA-encoded files.
Yes, the unit features switchable fixed or variable outputs on both XLR and RCA connections. This allows you to control volume directly from the DAC when connected to a power amplifier or active speakers.
Musical Fidelity intentionally omitted wireless connectivity to prioritize signal purity and minimize electromagnetic interference. This design choice ensures the cleanest possible audio path from your wired digital sources.
The M8x features a robust, fully balanced Class A headphone amplifier that delivers 3.2 watts into 32 ohms. It is designed to drive a wide range of headphones, from 8 ohms up to 300+ ohms, with ease and authority.
The I²S input provides a direct digital connection that separates the clock signal from the data, which can result in lower jitter and improved timing accuracy compared to standard S/PDIF connections when paired with a compatible source.
The M8x is compatible with both Windows and macOS. While it is plug-and-play for many applications, you will need to install the appropriate drivers to utilize ASIO or WASAPI protocols for bit-perfect high-resolution audio playback on Windows.
