DAC Module
The Gryphon DAC module available for optional installation in the Zena preamplifier is based on the acclaimed Gryphon Kalliope D/A converter with the well-regarded ESS Sabre ES9018 chipset. Critics around the world praise the breakthrough design and performance of the Kalliope:
“Amazing realism and utterly analogue fluidity. A total success!” - Haute Fidelité, France
“It is hard for me to imagine a more musically accurate DAC in the marketplace today.” - Enjoythemusic.com, USA
The module includes asynchronous USB, AES/EBU, optical, and dual S/PDIF coaxial connections. The USB input accepts signals of resolutions up to 32-bit/384kHz PCM and DSD512; the remaining inputs are limited to 24/192 PCM signals. Gryphon’s DAC module permits the activation of selectable PCM and DSD filters via the preamplifier menu system. Slow roll-off (short group delay) and sharp roll-off (long group delay) digital filters are available on the PCM side, while for DSD a first-order, analogue filter can be bypassed or set at 50, 60, or 70 kHz (50 kHz is the default).
