The LS1's frequency response is unusually flat - indeed the flattest we've ever measured.
Keith Howard, Hi-Fi News, Croydon (LS1)
Did Grimm Audio reinvent the loudspeaker?
Bert Oling, Hi-fi Video Test, Nijmegen (LS1)
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 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)
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)
A signal that sounds pretty decent with a good clock, sounds just incredible with the Grimm Clock.
Hay Zeelen, Hay Zeelen Mastering, Amsterdam (CC1)
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)
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)
A fantastic experience to work with this device.
Hein Dekker, producer for Channel Classics, Baarn (AD1)
Steve Hall, Future Disc, Los Angeles (AD1)
I'm now using a DSD converter called a GRIMM for my SACD mastering. Big improvement.
Steve Hoffman, Audio Fidelity, Los Angeles (AD1)
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)
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)
We are very impressed by the quality of this unit.
Günther Pauler, Pauler Acoustics, Northeim (CC1)
I was in the opportunity to hear your CC1 unit and I have to say INCREDIBLE!!
Carlos Imperatori, Producciones Tumbador, Caracas (CC1)
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)
I didn't know clock influence was that big!
Tim Vine-Lott, Air studios, London (CC1)
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)
The jitter measurement results of the CC1 were the best of all competitors.
Friedemann Kootz, Studio Magazin, Oberhausen (CC1)
One for all and everything.
Fritz Fey, Studio Magazin, Oberhausen (LS1)
I'm in tears, listening to my own recordings.
Ben Zijlstra, Dutch Film & Television Academy, Amsterdam (CC1)
Sensational! I have never found this quality in any commercial AD converter.
Ronald Prent, Galaxy Studios, Mol (AD1)
This is a larger improvement than I expected. The sound actually gains quality in all aspects.
Marnix Bosman, HVT magazine, Baarn (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)
A world class machine!
Yasushi Hamase, Be-Tone Studio, Kanagawa-Ken (AD1)
It seems as if the musicians have more fun when they play music.
Ingo Iebhart, hifi enthusiast, Eberdingen (CC1)
I had expected a small sound improvement. What happened is just the opposite: I am very impressed.
Gerd Hoppe, hifi enthusiast, Alicante (CC1)
Suddenly and distinctly, there's a palpable increase in naturalness, extension and spaciousness.
Nicholas Bedworth, Positive Feedback, Makawao (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)
