Grimm Audio’s CC1v2 was developed as a low jitter reference clock for professional studios but audiophiles discovered it was also a great device for cleaning up the digital audio path between their source and DAC. In addition, a music source with word clock input can benefit from joining it to the CC1. Now, ultimate musical timing and stability of tone is in reach of any caring audiophile.

Grimm Audio’s extensive research into the correlation between jitter and sound quality brought to light that emotional response to music is vastly more sensitive to jitter than previously realised. Attention turned from “making jitter low” to achieving the most stable clock possible. This research turned up a surprising array of previously underestimated performance factors like power supply noise, oscillator control circuit noise and low-level crosstalk. Owing to a radically redesigned discrete crystal oscillator, clock stability betters that of even the best test equipment available.

To sync to an external reference the CC1 sports a PLL offering an astounding 90dB of jitter suppression at 10Hz, further improving at 60dB/dec. The CC1 offers base rates of 44.1kHz and 48kHz and 1/2/4 multiples in separately selectable groups, in addition to an AES/EBU reclocker for cleaning the digital feed to your DA converter. Like all Grimm Audio products, the CC1 features striking styling and solid build quality.
