Grace Design m920 High Resolution Headphone Amplifier and D/A Converter

Designed for discerning audio professionals in the music recording, audio post-production and broadcast markets, the m920 provides unrivaled audio performance, coupled with a comprehensive and intuitive feature set. The heart of the m920 is the latest generation M series Sabre DAC. The Sabre is a 32-bit converter that takes DAC performance to an entirely new level. 24-bit, 192 kHz inputs are provided on AES3, S/PDIF, TOSLINK, and asynchronous USB. The m920 includes DSD-64 and DSD-128 functionality via USB, DSD-64 through the AES3 or S/PDIF inputs, and 352.8 kHz and 384 kHz PCM (DXD) playback over USB. User selectable DAC filter response is available for both PCM and DSD playback. Grace has improved the performance of its s-Lock PLL for increased jitter rejection, and the ability to disable this if not needed for a particular application. A new cross-feed circuit has been developed for improved headphone imaging, and low frequency response has been improved on the balanced and unbalanced line outputs.
