Offered is „MU 1“ by Grimm Audio as second-hand device from the category „Digital Sources (CD/DVD/Streamer...)“ on audio-markt.de - the online market place for high-end. The advert with the number 8607447370 ends on 16.10.2026 at 15:24 o'clock.
Good condition at €9,000 lands right on the market median for recent comparable EU listings, so this reads as a fair ask rather than a bargain or an inflated price. It is not cheap, but it is squarely in line with what a clean example has been changing hands for, so there is no pricing penalty here.
That makes it the kind of listing worth considering on merit: the MU1 is highly regarded for its serious digital front end, polished software experience, and “set it and forget it” convenience for a reference-level source. If it is complete and properly cared for, the upside is mostly in avoiding the premium and wait that often come with buying new; at this level, condition, provenance, and included accessories matter more than haggling.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Founded in 2004 in Veldhoven, The Netherlands, Grimm Audio emerged from the expertise of audio pioneers Eelco Grimm, Bruno Putzeys, Guido Tent, and Peter van Willenswaard. Drawing on their backgrounds at Philips and Hypex—where they advanced Class D amplification and precision electronics—the founders merged scientific rigor in acoustics, physics, and electronics with decades of critical listening. This heritage birthed early innovations like the AD1 1-bit A/D converter for DSD recording, the CC1 master clock, and TPR studio cables, establishing Grimm as a bridge between professional engineering and audiophile passion.
Grimm Audio specializes in high-end active loudspeakers, digital music players, and streaming DACs, alongside pro audio tools. Standouts include the LS1 series playback systems, delivering coherent full-range sound from 20Hz to highs with integrated amplification; the MU1 and MU2, ultra-low-jitter sources supporting Roon, UPnP, and AES for pristine digital retrieval; and legacy converters and clocks used in elite studios like Wisseloord and Channel Classics. Their holistic approach optimizes the entire audio chain for transparency.
Positioned as a niche boutique leader in the ultra-high-end market, Grimm commands reverence among discerning hi-fi enthusiasts and top recording professionals for perceptual neutrality and emotional fidelity. Acclaimed as "the world’s best complete audio system" by critics, their gear sets benchmarks in studios worldwide and luxury homes, prioritizing uncompromised musical truth over compromise.
