LS1 design presentation for Dutch AES

2009, November 19th
aes 191109 lecture For the second time the AES Netherlands section invited us to give a presentation about our design strategies. This time we decided to stage our brand new LS1 DSP corrected loudspeaker. Bruno talked about the fundamental issues one has to address when designing a loudspeaker of reference quality and afterwards the group of 60 attendents split into groups for listening sessions.

Anechoic chamber measurements

2009, November 18th
Anechoic chamberWith DSP controlled speakers like the LS1 the quality of frequency response measurements is transferred almost directly into the speaker's frequency curve. The quality of the measurement can therefore make or break the end result. We are very glad we could add a series of real anechoic chamber measurements to the quasi-anechoic measurements in our lab and garden. Many thanks to Utrecht School of Music Technology in Hilversum for that.

CC1 review in Music Emotion

2009, November
Music Emotion CC1Dutch hifi magazine Music Emotion featured a review of the CC1 by Jan de Jeu. On a test where the CC1 reclocks the spdif line of his CD transport he writes: "... A beautiful stereo image. Normally I never play this disc until the end but this time I keep listening breathlessly. Amazed by the difference I keep switching back and forth. (...) Both ends of the spectrum are beautifully expressed in the sound of the organ and brass instruments. The texture of the brass instruments is fabulous."

Hilarious forum conversation

2009, August
Audio ExoticsThe forum of our HongKong Hifi products distributor Audio Exotics had this hilarious conversation: "DSo was complaining to Marvel about me bringing this CC1 to his home just when he felt his system was in optimum state. Later on, he SMS-ed and said, "PT, after you took back the CC1, I had no mood to listen tonight. As a result, I went out drinking with friends."

AD1 for Nat King Cole mastering

2009, May 30st
Nat King ColeFrom the Pure Super Audio blog: "As some of you know, Kevin Gray and I have been working on a bunch of wonderful Nat "King" Cole Capitol Records' reissues for Acoustic Sounds/Analogue Productions over the past 1/2 year. (...) For us, in that situation, the Grimm AD1 DSD converter killed the [competitor]. It sounded exactly like the analog, both tone wise and ambiance wise. Very impressive."

A signal that sounds pretty decent with a good clock, sounds just incredible with the Grimm Clock.
Hay Zeelen, Hay Zeelen Mastering, Amsterdam (CC1), quote from interview in the Dutch 'Interface' magazine, June 2009
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)
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)
We are very impressed by the quality of this unit.
Günther Pauler, Pauler Acoustics, Northeim (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)

 

I didn't know clock influence was that big!

Tim Vine-Lott, Air studios, London (CC1)

 

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)

 

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. There is a dramatic increase in space and resolution. The sound is very coherent, all spectral parts of an instrument are localised at the same spot, both tones and noises. There is a dramatic increase in realism. This is really a big step forward for sound reproduction technology. It's been a long time that a recording of my own gave me the chills like this. The AD1 has revitalised my enthusiasm for this beautiful metier!

Leo de Klerk, Bloomline Studio, 's Gravendeel (AD1)

 

A world class machine!

Yasushi Hamase, Be-Tone Studio, Kanagawa-Ken (AD1)
Congratulations, you have made the best sounding AD converter I have ever heard! (...) The AD1 made the most realistic recording of my piano that I have ever heard. It was better than any digital or analog that I have ever heard. Incredibly realistic and involving.
Mark Conese, Ambient Records, Stamford (AD1)
Very impressive.”
Steve Hall, Future Disc, Los Angeles (AD1)
Sensational! I'm shocked, in a positive sense: this makes me very happy! I have never found this quality in any commercial AD converter.
Ronald Prent, Galaxy Studios, Mol (AD1)
