Warm Audio WA-CX24 Stereo Large-Diaphragm Tube Condenser Microphone

The Grimm Audio MU2 is a pinnacle High-End Hi-Fi Streamer with DAC (Digital-to-Analog Converter). It seamlessly integrates a powerful music streamer, a revolutionary, Grimm-designed DAC, a precision Preamplifier, and a state-of-the-art Master Clock into one elegant chassis. It is engineered to reproduce digital audio with the utmost precision and musical integrity, making it a true reference-grade component.

The MU2 is regarded as one of the Best Hi-Fi Music Streamers due to Grimm's uncompromising application of professional audio technology to the high-end home environment. A core reason is the integration of Grimm's renowned Clocking Technology (such as the Pure Nyquist Clock). This extremely accurate timing system minimizes jitter (timing errors) to an absolute minimum, ensuring that the digital data is delivered to the DAC perfectly timed. This results in unparalleled clarity, soundstage precision, and naturalness of musical reproduction. Additionally, the unique FPGA-based DAC and innovative analog preamplifier contribute to its outstanding sonic performance.

Grimm Audio utilizes an FPGA (Field-Programmable Gate Array) at the heart of the DAC. Instead of relying on off-the-shelf DAC chips, Grimm's engineers developed and programmed their own proprietary DAC algorithm directly onto the FPGA. This allows for highly customized and extremely precise digital signal processing, especially for upsampling and the Master Clock control. The patented FPGA DAC within the MU2 performs the Digital-to-Analog conversion with unmatched control and accuracy, setting new benchmarks for low noise and distortion.

Yes, the MU2 features a high-performance analog preamplifier with a unique volume control mechanism. The volume is regulated by a purely analog network of relay-controlled, high-precision resistors. This method is transparent, free from digital attenuation, and guarantees maximum sonic quality across the entire volume range without compromising resolution—an essential feature for a true High-End Hi-Fi Music Streamer.

The MU2 is primarily a Roon Ready device. Using Roon (a separately available music management system), you gain access to major streaming services like TIDAL and Qobuz in the highest possible quality. Roon also serves as the intuitive and feature-rich interface for controlling and managing your entire music library. Additionally, the MU2 can be controlled via the dedicated Grimm Audio App.
