Grimm Audio has announced a comprehensive firmware and software update for its acclaimed LS1 speaker system, marking a significant milestone in the company’s commitment to delivering exceptional audio quality. This free update, now available to all LS1 owners, represents a complete rebuild of both the LS1 firmware and the LS1 Control software, designed to enhance stability, sound quality, and user experience. The announcement underscores Grimm Audio’s dedication to supporting its existing customers with cutting-edge advancements in audio technology.

  • A Leap Forward in Sound Quality and Stability
  • Redesigned LS1 Control Software
  • Updated LS1 Manual
  • A Testament to Innovation
  • How to Access the Update

A Leap Forward in Sound Quality and Stability

The new LS1 firmware update introduces substantial improvements in both stability and audio performance. According to Grimm Audio, this update forms the foundation of the international acclaim for the LS1c model and delivers a noticeable upgrade in sound quality for all LS1 systems. The revamped firmware not only enhances the listening experience but also paves the way for future sonic and functional improvements, ensuring the LS1 platform remains at the forefront of high-end audio.

Redesigned LS1 Control Software

Accompanying the firmware update is the completely reengineered LS1 Control software, compatible with PC, Mac, and Linux systems when used with a Grimm Audio USB interface, such as the LS1i, UC1, or Grimm Audio USB Control cable. The software boasts an intuitive interface inspired by the MU1 GRUI web interface, providing seamless access to all LS1 settings, including source selection, volume control, and mute functions.

For professional audio users, the LS1 Control software offers advanced features tailored to sound engineers working on mixes or masters. These include direct control over specialized functions not available in the MU1 GRUI, making it an essential tool for studio applications. Additionally, the software enables LS1 firmware updates, a capability exclusive to the LS1 Control platform and not supported by the MU1.

Updated LS1 Manual

To complement the software overhaul, Grimm Audio has rewritten the LS1 manual from the ground up. While currently presented in a basic layout, the manual provides in-depth insights into the LS1’s features and the new LS1 Control software. It serves as a valuable resource for both audiophiles and professional users, with plans for a stylishly formatted physical version to be released later this year.

A Testament to Innovation

Grimm Audio credits the success of this ambitious project to the expertise of LS1 software engineer Simon Jaasma and chief software engineer Michiel Schriever, whose groundbreaking work in DSP processing has pushed the LS1 platform to new heights. The company emphasizes the scale of this undertaking, describing it as a testament to their commitment to advancing audio excellence.

How to Access the Update

LS1 owners can download the LS1 Control software and firmware update from Grimm Audio’s software update page. The firmware is integrated into the LS1 Control software, and detailed instructions for performing the update are available in the Software Install Guide on the same page. Users with an MU1 will need to temporarily connect a computer with a Grimm Audio LS1i interface or USB Control cable to apply the update. For those using a UC1, a separate UC1 firmware update is required first.

Publisher

Marco Lisi is the publisher of Best of High End, part of AV Concepts BV. His path into audio started early: as a teenager he was drawn into the world of free radio, presenting shows and living immersed in music every day. In his early twenties he ran his own production studio for five years, creating jingles and commercials — hands-on training in sound design, pro-audio workflows, and critical listening through studio monitors that still shapes how he evaluates gear today. He also spent years DJing in clubs before moving into publishing, first at two earlier online magazines before founding Best of High End. His hi-fi and home cinema passion was inherited from his father, an inveterate system-swapper. Marco's first setup — a confirmation gift — paired AKAI separates with entry-level Bowers & Wilkins speakers, a brand he stayed loyal to for years as his system grew from stereo into full surround and home cinema. Like many enthusiasts, he went through an extended "audiophile" phase chasing the next upgrade, before settling into a more grounded view: gear as a means to enjoy music and film, not an end in itself. Years of critical listening have given him a well-trained ear — the ability to characterize a system or pinpoint a change in the chain quickly and accurately. Just as important, his teaching background (a Belgian "regent" degree in Dutch language) gives him the tools to translate those listening impressions into clear, readable writing.
