Professionals and audiophiles alike will simply be floored by the m902’s latest generation, high performance 24/192 DAC. It also includes the unique s-Locktm dual stage PLL (Phase Lock Loop) for extremely low intrinsic jitter and rock solid digital performance. A full array of digital and analog inputs are available (including USB) which are all selectable via front panel rotary switch.

     The m902 also includes an exciting new feature to stimulate the acoustics of a loudspeaker listening environment. Which at the end will reduce listening fatigue when using headphone for extended period. This new feature employs carefully designed signal crossfeed, filtering and delay circuits to stimulate HRTF (Head Related Transfer Functions).

     Additionally, the M902 cleverly adds stereo analog line outputs for connection to studio monitors. Which also allow it to function as an elegantly simple high fidelity monitor controller or even a purist audiophile preamplifier/DAC.

     At the core of the M902 is the meticulously designed high-current trans-impedance amplifier circuitry. It will effortlessly drives any headphone out there, even the ones with lowest impedance. This no compromise circuitry provides the high resolution and low level ambient detail which all Grace Design products are famous for. The signal becoming transparent and alive, so the critical details in editing and mastering becomes an easy task.
