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.
Max Schlundt, Kultur...Technik, Berlin (LS1)
This is probably the most 'correct' loudspeaker I've ever laid ears on. The combined honesty, neutrality and pleasing musicality is at a level that I haven't come across before.
Christian Rechenbach, EinsNull magazin, Duisburg (LS1)
The CC1 is a brilliantly designed piece of equipment. Every piece of gear that I plugged into it sounded better and more natural.
Erik Zobler, Mix Magazine, Los Angeles (CC1)
The LS1 seems to be a melting pot for all your expertises. I just find it fascinating. I am quite certain that the LS1 is at least the very very best 'value' in the market right now.
Wai-Shan Lam, hifi enthusiast, Hong Kong (LS1)
Grimm Audio enriches the Loudness Movement with exceptionally price worthy and designful tools.
Dieter Kahlen, Studio Magazin, Oberhausen (LevelView)
We are very impressed by the quality of this unit.
Günther Pauler, Pauler Acoustics, Northeim (CC1)
I didn't know clock influence was that big!
Tim Vine-Lott, Air studios, London (CC1)
The jitter measurement results of the CC1 were the best of all competitors.
Friedemann Kootz, Studio Magazin, Oberhausen (CC1)
After all these years I finally have a standard on which I can rely.
Al Pryor, Mack Avenue records, Hempstead (LS1)
I was impressed by how my chain with the EMM's got a benefit when I added a Grimm clock to my setup. Guided by what the literature and many designers are saying I was stunned about the change in a positive way) in sound.
Daniel Dettwiler, Idee und Klang Studio, Basel (CC1)
Steve Hall, Future Disc, Los Angeles (AD1)
I was in the opportunity to hear your CC1 unit and I have to say INCREDIBLE!!
Carlos Imperatori, Producciones Tumbador, Caracas (CC1)
I was focusing more on the music than the equipment, something that rarely happens when I listen to digital...
Tony Bolton, Hi-fi World, London (CC1)
You have to work hard on the LS1's to get a good sounding mix, but once you have it, you can be sure it really is a good mix.
Wessel Oltheten, Pro Audio & Video magazine, Buren (LS1)
I have used all high end AD converters known to date. Every one of them had a sound to it. Your converter doesn't: it is completely transparant!
René Gambini, Lyrinx, Marseille (AD1)
Realize that not all timepieces are created equally. In this regard, the Grimm CC1 has no peer.
Bob Katz and Garrett Haines, TapeOp, Sacramanto (CC1)
One for all and everything.
Fritz Fey, Studio Magazin, Oberhausen (LS1)
This is a major improvement. We need much less eq on the high end, the low end sounds more solid and the punch on the snare is great. This clock is a large improvement, we were amazed.
Peter Riebeek, Studio 150, Amsterdam (CC1)
This is a revelation. It is the first time in my 20 years of digital recording that I hear a fundamental improvement in sound quality.
Leo de Klerk, Bloomline Studio, 's Gravendeel (AD1)
This is a larger improvement than I expected. The sound actually gains quality in all aspects.
Marnix Bosman, HVT magazine, Baarn (CC1)
It seems as if the musicians have more fun when they play music.
Ingo Iebhart, hifi enthusiast, Eberdingen (CC1)
I heard the LS1 in NYC at the AES Convention... man, I was really impressed. Although it was at the booth, I could identify my mix immediately. So far the best speakers I've heard.
Christian Klotzbücher, Kunstuniversität Graz, Graz (LS1)
I'm now using a DSD converter called a GRIMM for my SACD mastering. Big improvement.
Steve Hoffman, Audio Fidelity, Los Angeles (AD1)
Last week I was recording a strings section and piano. My client was very happy and he asked me if I changed something in the studio. Of course, it was your CC1.
Josep Umbria, Calma Estudis, Manacor (CC1)
I had expected a small sound improvement. What happened is just the opposite: I am very impressed.
Gerd Hoppe, hifi enthusiast, Alicante (CC1)
I did some sessions in 44.1, 48 and 96. It works great, and sounds fantastic. The CC1 is such a great upgrade in the studio, amazing!
Samuel Girardin, Point d'Orgue, Montreal (CC1)
Did Grimm Audio reinvent the loudspeaker?
Bert Oling, Hi-fi Video Test, Nijmegen (LS1)
The LS1's frequency response is unusually flat - indeed the flattest we've ever measured.
Keith Howard, Hi-Fi News, Croydon (LS1)
Suddenly and distinctly, there's a palpable increase in naturalness, extension and spaciousness.
Nicholas Bedworth, Positive Feedback, Makawao (CC1)
A signal that sounds pretty decent with a good clock, sounds just incredible with the Grimm Clock.
Hay Zeelen, Hay Zeelen Mastering, Amsterdam (CC1)
A world class machine!
Yasushi Hamase, Be-Tone Studio, Kanagawa-Ken (AD1)
Sensational! I have never found this quality in any commercial AD converter.
Ronald Prent, Galaxy Studios, Mol (AD1)
I was thrilled with your power supplies for my Neumann M50's. We used those mics for an upcoming Chandos release of the Kansas City Chorus, and they were stunning.
John Newton, Soundmirror, Boston (MP1)
The AD1 made the most realistic recording of my piano that I have ever heard. Incredibly realistic and involving.
Mark Conese, Ambient Records, Stamford (AD1)
I'm in tears, listening to my own recordings.
Ben Zijlstra, Dutch Film & Television Academy, Amsterdam (CC1)
Throughout even the most turbulent passages the recording space stays luxuriously illuminated and the soundstage remains absolutely clear.
Reinhold Martin, Hifi Statement Net Magazine, Gröbenzell (CC1)
A fantastic experience to work with this device.
Hein Dekker, producer for Channel Classics, Baarn (AD1)
