Here we go again. For the Spanish Hifi magazine Revista On Off, Josep Armengol reviewed the LS1 plus LS1s subs. He writes:

 

“The transparency of the sound is tremendous. One could really think that you have the artists in front of you. Grimm's mission to eliminate the sound of the system and present just the original recording seems totally true. At the same time, if the system is fed with less than optimal recordings, the sound does not become unpleasant, which is often a problem with other studio monitors that can be too analytic.

 

The sub woofer is very well integrated, I even touched them to see if they were working. This is of course the ideal: that subwoofers perform their duty unnoticed. The set offers a well defined low end, rhythmic and deep, never exaggerated, in fact for some rock discs I added a dB of low end in the LS1 software just for fun. 

 

The magnificent Grimm LS1 boxes always seem to get the best out of a recording and let you enjoy the spirit of the music, but in a very different manner than - for example - a traditional system with valves, with a romantic sound. But even so you end up listening for long hours because you don’t feel any sign of fatigue. And along the way you discover details in discs that you thought you knew in depth. Noises from the studio, sheet music moving, fingers on instruments, whispers ... impressive how the Grimm’s unveil ‘everything’.”

Over the years the LS1 has seen some significant improvements, reason why the current LS1 sounds better than the LS1 from a couple of years back. We also introduced a new flagship product recently, the LS1be. Whenever we improve our products, we ensure our existing custromers can profit too. So we like to offer them the option to update their LS1 to the current level or even upgrade their LS1 to the level of the LS1be! Please read the linked brochures and contact your dealer for more information.

We are delighted to present yet another review that sings the praise of the LS1. The experienced editor in chief Jack Liu of the Taiwanese magazine Audio Art was highly impressed by the performance of the LS1 and offered it the full score on all 20 evaluation points! Some excerpts from his poetic text:

 

“I listened to a cello and piano recording from the album ‘Antonio Lysy at the Broad: Music From Argentina’. The LS1 reproduction of this cello and piano piece has two very charming aspects: the sound quality is both very beautiful and very true to life. Actually these two qualities describe the main character of the LS1 very well. And tell me, is there anything more desirable than to have a beautiful and sweet sound? And what is more exciting than a playback that almost sounds like reality?”

“To listen to some pop music, I selected Lorna Hunt’s "All in One Day." The LS1 performance again made me cheer of joy, because the drum sound was elastic, solid and clean, the guitar was crisp, sweet and delicate, and Hunt's voice sounded natural in a loose way, without any exaggeration. In my experience, such an open, relaxed character can normally only be found with big loudspeakers.“

“There was no audible compression at all, everything sounded open without any clutter, the frequency balance was perfect, down to very low frequencies. This is only a three driver system in a very small enclosure but the large-scale orchestral music performance was so real. Forgive me my ignorance, but this is the first time I heard a playback like that. In particular, the orchestral brass texture was very realistic, with proper weight.“

“As a final, I played Tchaikovsky's Fifth Symphony by the Russian National Orchestra with Pletnev as conductor. After listening, I saluted the LS1. Maybe very large speakers can offer even more impact, but that ultra-high resolving power, the clear presentation of musical layers, the very beautiful and musical sound, the very real texture, the amazingly fast transient response, the direct and non-fogged transparency, and the nailed down positioning of the instruments, leave the listener gasp in admiration.“

“Accurate, transparent and beautiful, that is the Grimm Audio LS1.”

We have another rave review for the LS1, this time in the Norwegian magazine “Stereo+” (does the LS1 have the world record for 5 star reviews by now?). Look at what Roy Ervin Solstad has to say about the LS1:

“Grimm shows that it is worth lending an ear to the pros. They know what they're doing.”

"From the beginning, the thing that impresses most is the Grimm LS1's ability to disappear completely. The sound stage is extremely homogeneous without any flaws, and the holographic precision of the sound is exemplary. Musicians and singers are nailed in a wide and deep sound stage."

"One can turn up the volume to obscene levels without any kind of trouble. Never before have I feared that a speaker would dislodge the floorboards of my living room. It is simply the craziest full range level I have ever experienced at home. And this with complete control, definition and resolution."

"The whole thing is so clean, and without a single audible blemish, not even from the room. They're definitely not the kind of tool for those who enjoy tuning their system in one direction or another. These speakers are basically designed for monitor use in a studio. They show everything the way it is recorded, and that is precisely what you hear when you have them in your living room. For such a precision instrument, it is no surprise that the sound balance is extremely neutral. But at the same time the wonderful openness is enchanting. There is so much space around all instruments and voices, that I can not remember ever hearing it better."

"I've played everything from Rammstein to chamber music on these speakers, and they eat everything raw. It is only what you feed this setup that determines what you get out at the other end."

"You will have to go to great lengths to find something that matches this sound quality for the same price. What more can one wish for."

The local newspaper of Eindhoven, “Eindhovens Dagblad” had a one page article about our company in the Economics pages. Guido Tent and Eelco Grimm were interviewed by ED’s journalst Hanneke van den Nieuwenhof and elaborated on the companies’ mission: “We distinguish ourselves from large companies because we strive for perceptual neutrality. And we distinguish ourselves from other small companies by having knowledge of all components in the whole chain from sound to sound.”

We are very happy to announce a major update of the PC & Mac control software for the LS1 playback system. The update focusses on improving the user experience, but also adds new functionality. An equalizer with user presets is added, that offers delicate adjustment of the LS1 response to taste. Its low frequency EQ can be set separately for left and right, so both speakers can be tuned individually to their acoustical environments. With the new user interface and the EQ, an LS1 playback system becomes even more easy to setup in a living room or studio. To complement the new LS1 Remote software, the LS1 manual was completely rewritten. It now is an even better read than it already was.

We made a beautifully detailed 3D model of the LS1 White Corian version for you. You can use it in the popular 3D design environment Sketchup (formerly of Google, now Trimble). It is available via Sketchups 3D Warehouse or via direct download from our Downloads page. And for the real fans, you can download a 3D printer file of the LS1 as well (check the 3D warehouse for that)!

The Netherlands' most prominent Hifi magazine "Hifi Video Test" wrote in their show report about our High End Munich demo with Native DSD Music the next phrase: "Imagine having missed the presentation of Native DSD and Grimm Audio. Five LS1's playing the masters of the masters (Daan van Aalst and Jared Sacks). Best sound of show, stunning, Meisterhaft.". In the picture: Daan van Aalst and Eelco Grimm.

The LS1 has been awarded a 'Writers' Choice Award 2014' by Positive Feedback Online! Their reviewer Timothy Roth wrote:

"The Grimm LS1 is revolutionary on numerous fronts. In terms of flat frequency response, transient response, and correct phase, it measures better than any speaker ever made. It is also designed to bring the mastering studio, where the final creative decisions are made, and the living room together. They are groundbreaking in their price point and in bringing the entire audio chain together into a single tweak-proof system so that, when using a digital signal, nothing can color the sound. These speakers redefine the promise of "High Fidelity": they play back the pressure waves encoded on the record, nothing more, nothing less. But apart from the mind-blowing measurements, they are quite simply the most immersive, dynamic, detail-rich, nuanced, elegant, engaging, emotional, and musical speakers I have ever heard. Max Schlundt, of Kultur Technik, has boldly stated "If someone came up with the idea to call the LS1 the best speakers he's ever heard, I would join in with a smile." I'll be even more bold: These are the best speakers on the planet. Period."

Wow, that's the greatest Christmas gift we could wish. We are very happy and proud!

We are speechless with gratitude for the most incredible LS1 review ever written. Author Timothy Roth of Positive Feedback Online wrote an invitation to both music lovers and professional engineers to unite their worlds by embracing the LS1. In his words: "The LS1 brings the mastering studio into your room, which is a revolutionary paradigm shift. You hear the artists' intent rather than your system or your own personal preferences." This was exactly our original aim when we designed the LS1. Please read the full review to be swept up in his enthusiasm for the LS1: "As it turns out, Truth equals Love."
