In the first review of the LS1be, our new flagship product continues the “5 star saga” of the original LS1. Jaap Veenstra of the Dutch online hifi magazine “Alpha Audio” writes in his conclusion: “We don’t often have tears in our eyes when listening to music at our office. Now we do. The achievements of the LS1be are very impressive. So clean, so involving and so full of - yes: emotion. You then have to be a cold frog if you’re not moved to tears by your favorite music. We do not want to spend too many words on metaphors and backgrounds. Just visit a dealer and listen to this triumph from The Netherlands. Forget everything you think you know about digital, DSP and active speakers. So did we… And let the LS1be bring you back to the essence: enjoy music. More intense than ever.”

CC1 demands for a remix2016, September 8

There’s nothing like getting feedback from a very happy customer! John Davis of The Bunker Studio in New York bought a CC1 and wrote:

“Your clock has really transformed the sound of our digital rig. The transparency of the soundstage and accuracy in the time domain is really stunning and brings out a level of detail and clarity that I had dismissed as only possible with analog. I had a client ask why my mixes were so much better this week (I had mixed half the album last month)…. and actually decided to remix two songs, because the difference in the end result was that obvious.”

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 received an impressive testimonial from LS1 customer Thaddeus Moore, that we love to share with you:

"I want to congratulate you for making the best sounding, most phase linear, transient accurate, and all around beautiful speaker system on the planet. I’ve only had the opportunity to be in front of them for a short while and have had the best listening experiences of my life. Thank you for all the work you and your team have put into these. I have already made better, faster decisions in my mixes, and have had more confidence in delivering my masters. 

You should code name the LS1 "Red Pill". Because once you have them you can't go back into the matrix of illusion…"

Thaddeus Moore, Liquid Mastering, Eugene

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."

At the Munich High End show Grimm Audio will introduce three new products. The most prominent novelty is the LS1be. This top class music playback system features a new ultra light Berylium tweeter with a CNC milled aluminium waveguide, jointly developed by Grimm Audio and Seas. We selected Hi-Macs for the new cabinets, a modern and very rigid material, and it looks great too! 

For the low end we added the new LS1s-dmf subwoofer. Mechatronics expert Rob Munnig Schmidt developed a Digital Motional Feedback system that, by means of feedback from an accelerometer on the cone, reduces distortion by a staggering 30 times. This leads to a clean, tight and natural bass that is the perfect partner for the delicacy and precision of the Berylium tweeter. The full LS1be system brings the listener again closer to an experience of total transparency, which is our company’s ultimate goal.

To bring the LS1 quality to a broader audience, Grimm Audio introduces the LS1a. This is a more cost effective sibling of the LS1, where the company focussed on maintaining all important aspects that make the LS1 sound so special, and compromising only in areas where this was passable.

Dutch online hifi magazine “Alpha Audio” did a shoot-out review of interlinks. TPR was ranked as ‘The Best’. “The sound stage renders almost holographic with a very high precision and spaciousness, as if there is no cable at all. (…) Localisation of instruments is precise and vocals are spot-on in the centre. (…) This interlink really let’s you hear everything in the music and does not mask a thing.”

The online resource "Pink Noise magazine" did an extensive article about "The future of clocks" and quoted our jitter white papers in various parts. They now added a review of our CC1 master clock and were extremely enthusiastic about its quality: "Quick summary: Allen bought one immediately!  This clock is incredible. The detail and imaging from it are superior to anything we heard, and the overall “relaxed” sound of the playback was as close to analog tape (read: jitter-free) as anything we’d tried. The Grimm CC1 didn’t make the music sound as aggressive and forward as the Antelope clocks, and that was a huge plus, because what you get instead is unparalleled depth and detail, as well as a feeling of “calm” that none of the other clocks provided.  Of course, the CC1 is simply a clock with no conversion available (like the Cranesong HEDD), but it seems there is something to be said for a dedicated clock, as whatever Grimm has done inside the CC1 is topping an elite class of options as a price less than half of some of the other offerings. Hands down, the CC1 was our preference."

The online pro audio magazine AudioTechnology, Issue 27, features an interview with John Hanlon who is longtime producer of Neil Young. In the article about recording Young’s latest album “The Monsanto years”, Hanlon talks about selecting a clock for the recording:

“When we use digital, Neil wants to go to the highest resolution available. We have done listening tests, and 192k sounds great, though it does depend on having a good clock. We have used the Apogee Big Ben, which I think is very musical, and I checked out the Antelope, Rosendahl Nanosync, Aardvard Aardsync and the new Pro Tools clock, and they’re all really good. We did a shoot-out and went with the Grimm Audio CC1, because it sounded the best with 24 bit / 192k and the new Avid HD I/O converters.”
