Grace Design m920
Limitless Engagement
From a company that’s been making highly respected pro audio gear for more than two decades, the Grace Design m920 is a fantastic all-in-one solution for sound engineers and audiophiles alike. This high-resolution monitoring system, now in its fourth generation, is packed with a wealth of features—and can function as a standalone DAC, amp, or preamp for your headphones when you need one. Notably used during the making of the Steinway & Sons CD label, it delivers the combination of transparent, detailed sound, non-fatiguing performance, and bombproof reliability that Grace Design is known for.
Note: At checkout, you will have the option to add a remote control (+ $95). This drop is limited to 7 units.
Features & Upgrades
Driven by the M Series 32-bit Sabre DAC, the m920 supports up to 32 bit/384 kHz PCM, as well as DSD64 and DSD128 playback. The DAC allows you to select between three digital response filter curves (fast, slow, and minimum phase) to balance for all the different genres in your music library. The high-current transimpedance output amplifiers can easily drive 8-ohm loads, making the m920 well suited for everything from the Audeze LCD-X cans to the Ultimate Ears in-ear monitors. Additional upgrades include a crossfeed function, a stereo balance mode, and remote control via an Apple remote or an iOS/Android device with the Logitech Harmony Hub.
