The free user-executable firmware update introduces several functional improvements and is a significant step-up for the already exceptional sound performance of the MC-3+USB. Among the features highlighted by MUTEC is a “painstakingly optimized re-clocking algorithm, improving the already exceptional sound quality to achieve even more clarity, resolution, and presence”, as well as the ability to auto-detect PCM/DSD signals via USB, allowing users to enjoy music up to 192 kHz PCM and DSD/DoP streams (up to DSD256 and DoP128 respectively) without the need for manual switching.
The update also introduces multiple bugfixes and functional improvements. As MUTEC details, the automatic detection of DSD and PCM streams when using the MC-3+USB for audiophile computer audio playback via USB was one of the most requested features and the most significant functional improvements of the new firmware. As MUTEC CEO Christian Peters comments: “Convenience is key for our high-end consumer audio customers and having to switch modes depending on the source file when playing back a mixed format playlist for example was a major nuisance. From now on, the user simply has to select the USB input from the reference menu (all top three LEDs now illuminate) and the MC-3+USB will automatically adapt to PCM streams with up to 192 kHz sampling rate and DSD/DoP (DSD256 and DoP128 respectively).”
Even more significant than this functional change are the sonic improvements that the new firmware introduces: “Our development engineers have painstakingly tweaked the DDS algorithms under the hood yielding a new level of sound quality. This is an achievement we’re particularly proud of and that all users will benefit from,” explains Christian Peters.
The new firmware was thoroughly beta-tested in the field and users have reported “sonic gains which are immediately apparent”. The update further strengthens the MC-3+USB’s position as one of the leading DDC (digital-to-digital) USB interfaces and re-clocking devices.
The firmware release package will contain several update files and a comprehensive guide taking the user through the process step by step. The update will be made available via MUTEC’s website as a zip-archive download. At the moment, the update is limited to Windows users only, but a Mac version of the update is expected to follow soon.
