A complete digital front end: streamer, DAC and preamplifier in one component
Grimm Audio components are typically ordered through Fern & Roby as part of a broader system conversation. Current lead times vary by product and configuration. We encourage clients to contact us before purchase to discuss system matching, availability, and fulfillment timing.
The Grimm Audio MU2 DAC is a reference-level digital front end that combines a Roon Ready music streamer, DAC and preamplifier into a single, fully integrated component. The Grimm Audio MU2 DAC, streamer and preamplifier is available through Fern & Roby as an authorized dealer, including optional 4TB internal storage configuration.
For systems built around an existing DAC, the Grimm Audio MU1 remains a compelling alternative as a dedicated streamer and server.
More than a convenience, the Grimm MU2 is designed to replace multiple components in a high-end system—simplifying setup while improving coherence, timing and overall musical engagement.
As an authorized Grimm Audio dealer, we recommend the Grimm MU2 as the central hub of a system built around long-term listening, not incremental upgrades.
What the Grimm Audio MU2 Does in a System
The Grimm MU2 isn’t just a DAC with streaming added. It functions as a complete digital front end:
Roon Core (with optional internal storage up to 4TB)
Roon Endpoint
TIDAL Connect and UPnP rendering
Grimm’s proprietary FPGA DAC
A fully realized analog preamplifier stage
In many systems, it can replace a separate Roon server, a standalone streamer, a DAC, and often even a line-stage preamplifier. This kind of integration is huge for clients who want to reduce system complexity without reducing performance.
Who the Grimm Audio MU2 is for
Listeners building a reference-level digital front end
Systems where streaming is the primary source
Those looking to simplify without compromising performance
Owners of high-efficiency speakers and resolving systems
Purchasing through Fern & Roby
As an authorized Grimm Audio dealer, we regularly help clients build systems around the MU2 alongside components from Technics, Weiss, Linear Tube Audio, DeVore Fidelity, and other products we know well through long-term listening and system building.
Christopher works directly with clients to discuss system matching, setup and integration, storage configuration, amplifier and speaker pairing and long-term system planning.
Our perspective
We think of the MU2 less as a “DAC” and more as the center of a system.
When used this way—often directly into a power amplifier—it can replace multiple components while improving overall coherence and timing.
In systems where streaming is the primary source, this kind of integration tends to outperform more complex chains of separate boxes.
Listening with the MU2
We’ve spent a lot of time living with the MU2 in our own system—not as a component in showroom, but as part of our daily listening system at home.
What surprised us wasn’t ease of use, but the engagement we felt. Streaming began to feel less like access and more like deliberate listening again—a meaningful complement to analog, not a replacement for it.
For a deeper look at how the MU2 reshaped our approach to digital, read Christopher’s listening notes.
Why we chose to carry the Grimm Audio MU2
The MU2 stood out to us for:
System coherence and ease of integration
Engineering precision without a clinical presentation
Long-term listening satisfaction
A design philosophy aligned with serious music listening
Optional 4TB internal storage
This is a component designed to be lived with, not cycled through.
Full MU2 specifications are available on the Grimm Audio website.
Thinking about the MU2 in your system?
We regularly help clients think through how the MU2 fits into both new and existing systems. Some of our clients are looking to simplify a more complex digital chain, and others may be building around streaming as a primary source.
Questions around amplifier pairing, storage configuration, speaker matching, and overall system balance are often just as important as the component itself.
If you'd like to discuss how the MU2 might fit into your system, Christopher works directly with clients on system matching, integration and configuration.
Frequently Asked Questions
Is the MU2 in stock at Fern & Roby?
Grimm products are configured and ordered through Fern & Roby based on system requirements and current availability. Lead times vary by product and configuration and may extend several weeks or longer. We encourage clients to contact us before purchase to discuss timing, setup, and system matching.
Is the Grimm MU2 a Roon Core?
Yes. The MU2 can function as a Roon Core and optionally includes internal storage for your music library.
Does the Grimm MU2 include a preamplifier?
Yes. It features a fully integrated analog preamplifier stage and can drive power amplifiers directly.
Can the MU2 replace a separate DAC and streamer?
In many systems, yes. It combines streaming, conversion, and volume control into a single chassis.
Does the MU2 include internal storage?
Internal storage is optional. The MU2 can be configured with 4TB of internal storage, or used with external drives and network-based libraries.
