Special Price: $2,180.00 Grace M920 High Resolution Monitoring System

 

The m920 stands on the shoulders of its predecessors then jumps to new territory in digital and analog audio performance.

Using the latest 32Bit Sabre DAC technology, the Grace m920 delivers up to 384kHz PCM and 64x and 128x DSD playback. The m920 provides state of the art DAC performance.

For home or studio, this is truly the ultimate, high resolution monitoring system.

The technology in the m920 is highly evolved and refined. Grace Design set out to lower the distortion, improve the noise performance, lower the DAC's jitter, and make it more reliable.

The new, world-class M Series 32-bit Sabre DAC provides an astonishing improvement in digital performance.

Redesigned s-Lock PLL circuitry improves jitter rejection. 

DSD64 and DSD128 playback brings great musicality to digital recordings. 

Features

Stereo analog inputs - balanced (+4dBu) XLR and unbalanced (-10dBv) RCA.

Ultra low distortion 32-bit /384khz Sabre DAC accepts stereo digital input sources in AES3, S/PDIF, TOSLINK (optical) and USB formats with auto sample rate detection and digital de-emphasis filter

User configurable DAC filter response for PCM and DSD playback

USB for playback of up to 384kHz / 32 bit PCM as well as DSD64 and DSD128 playback via DoP

AES and S/PDIF playback of up to 192kHZ / 24bit PCM as well as DSD64 playback via DoP

New dual-stage wide lock range PLL for improved jitter rejection on non s-locked sources

Third generation s-Lock™ dual stage PLL (phase lock loop) circuitry for the ultimate in low jitter clocking and sonic integrity

Two sets of line level outputs provided via RCA (unbalanced) and ¼ TRS jacks (balanced) for connection to stereo monitors

RCA line outputs can be configured for variable or fixed dac output mode for operation as a standalone digital to analog converter

Front panel rotary encoder provides precision level control of both headphone and the line output levels. Level adjustments are made in 0.5dB steps within a 95dB range

0.05dB channel level matching to ensure true stereo balance at any monitoring level

Large, white 7-segment display is used to show headphone and stereo main output levels

New X-feed (crossfeed) simulates the acoustics of a loudspeaker listening environment which can significantly improve imaging while reducing listening fatigue when using headphones. This feature employs carefully designed signal cross-feed, filtering and delay circuits to simulate hrtf (head related transfer functions)

High current transimpedance output amplifier design drives 8 ohm loads. The m920 was specifically designed with low impedance headphones in mind

Only the highest quality 0.5% metal film resistors are used throughout and there are no electrolytic capacitors in the signal path. Sealed gold contact relays are used for all signal switching

Infrared remote control for level control, left/right balance, mute and more when using the optional remote control unit

Apple IR remote control is supported with optional pairing

USB firmware upgradability

5 Year transferable warranty on parts and labor
