In their May issue, the German high profile magazin Audio Flatscreen Journal (of former ‘Audio’ editor-in-chief Joachim Pfeiffer) published a review of the LS1be: “A fairytale come true”. The LS1be is ranked highest of all speakers tested to date. In their words: 

 

“‘Unbelievable’ collegue Patrick Boch sighed, who could not stop to enjoy his Tidal playlist on the Grimm’s.” (…) “The real surprise for the listing team however came in the next session: we connected our analogue reference chain, consisting of turntable Transrotor Rondino, Audio Research Phono Reference 10 and Cello Audio Suite, to the analog input of the LS1be. Still going strong? You bet! The outstanding Grimm LS1be rendered the analog master source so relaxed, transparent, emotionally involving, and simply: correct, that the jury could only applaud.”

Dutch leading hifi magazine HVT did a review of the LS1be. Marnix Bosman was seriously impressed. He writes about a particularly difficult reference track of him, Miserere of Arvo Pärt by the Hilliard Ensemble: “With many systems the result is a severe mash-up, caused by distortion and coloration. With the LS1be the sound image stays airy and tack sharp. A great strength is the speed and immediacy of the playback. It also has a very beautiful low end, that not only goes to great depth, but is of exceptional pureness. Dry and fast with lots of detail and definition. Big drums or low organ registers become super impressive. A lot of fun can be had with electronic bass lines, that go to unexplored depths. The new sub plays effortlessly whatever you throw at it.”

His conclusion is: ‘Listen to the source’. “The LS1be is one of the few loudspeakers that present the listener unrestrictedly what the producers of the music intended to express. The LS1be does not add anything. No sweetening, no effects, but pure transparency, that’s the LS1be. The LS1be is not just a loudspeaker, it is a complete playback system. Combined with an arbitrary source an LS1(be) brings everything into your living room that’s needed to enjoy the recording of a musical performance in its purest form.”

The LS1be was selected by Jaap Veenstra of Alpha Audio as his personal "pick of the year" and it therefore received an "Alpha Audio Approved" Award! Jaap's verdict in translation: "The Grimm LS1be (had impact) because of the unprecedented truthfulness, without being lifeless or unemotional. The Grimm even went so far to give rise to tears during the listening session. That does not happen so often these days."

 

The Dutch consumer electronics ‘comparison’ site “BesteProduct.nl” (founded in 2006, 1032 own reviews per year, 600,000 unique visitors every month) has rewarded the LS1be with a “top 5” position in their “most outstanding audio and TV product of the year” competition. Within the top 5 there were just two audio products present. The verdict of besteproduct.nl in translation:

“This Dutch manufacturer aims high. Outside the Netherlands we already saw reviews in which the speakers were praised into the heavens. The German ‘Audio’ magazine judged the original Grimm LS1 as the best they tested in 35 years. The word ‘science fiction’ was mentioned, and not because of its form. Where high-end speakers sometimes resemble spaceships, these speakers from Grimm look pretty normal and would fit perfectly into any living room. They will probably not fit into everyone's budget at about 36,000 euros."

Tom Haze (besteproduct.nl)

 

"Insanely good active speaker. Minimalistic, very musical and pretty good looking. There’s plenty of inputs so everything can be connected."

Jaap Veenstra (Alpha Audio) 

 

We are very thankful for this reward!

 

Yet another rave review of the LS1be: in 6 Moons! Or… rave review? Henk & Marja write: “Even though it doesn't read like a rave, as experienced listeners will know, that really was most telling of all. This music system just did its job and got so perfectly out of the way that we could fully concentrate on and get immersed in the music.”. 

We are so proud that the LS1be has brought us here. Our mission is to bring total clarity to the professional and music lover. And with it a “total peace of mind”, which are the final words of the Henk & Marja review. 

Here is one more striking passage from their review: “another key characteristic was the lack of any character, fingerprint or voicing. This music system was neutral and audiologically speaking, honest to the bone just as its looks are clear but with exciting lines that change perspective with viewing angle to enhance the innate airiness of the design. Over the review period, we never once had the itch to do anything audiophile at all. No tweaking, no alterations… nothing. (…) Usually the itch to change something arises sooner than later. When it doesn't, take note and hold on to it!

Truly, this could be the last system you'll ever buy; an endgame solution.”

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.”
