Grimm Audio recently announced a new release (v1.2.14) for the firmware running in their critically acclaimed music player MU1. The main focus of this update is on the internal control software that manages all systems in the MU1
. According to the press release, the company decided to rebuild the control system from the ground up, to create an even more solid fundament, and at the same time add more flexibility in the architecture for future refinements. The user will experience a smoother operation and improved Roon integration. Also the display renders swifter and has sub pixel rendering for higher quality images. Firmware updates now download much faster.
New features are also added: optional volume control for both AES outputs, a DoP option for DSD DACs, up- and downsampling to 96 kHz or 88.2 kHz for digital systems that don’t support higher rates, adjustable power-on LED brightness, exFAT, HFS and HFS+ support for USB drives and a Grimm LS1 loudspeaker detection that disables the LS1 options in the source menu when no LS1 is present in the system.
MU1 is a Linux based computer system supporting a Grimm's, in-house designed, FPGA interface board, featuring the company's trademark ultra low jitter clock. The MU1 runs Roon Core server, but for customers who prefer to only run a simple playback system without Roon’s extras, there is, also a solid alternative, the company says.
The device supports standard digital connectivity through S/PDIF coaxial (RCA) and optical (Toslink) inputs, an AES/EBU (XLR) input, and Ethernet connectivity both for local resources (including NAS devices) and Internet streaming (Tidal, Qobuz and Spotify Connect services). It can also be used with external USB storage and optionally include an internal SSD if you need more storage.
