Grace Design m902
Reference headphone amplifier
  

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

The Grace Design m902 also includes a feature to simulate the acoustics of a loudspeaker listening environment, which significantly improves imaging while reducing listening fatigue when using headphones. This feature employs carefully designed signal crossfeed, filtering and delay circuits to simulate HRTF (Head Related Transfer Functions).

Additionally, the m902 cleverly adds stereo analog line outputs for connection to studio monitors, allowing it to also function as an elegantly simple high fidelity monitor controller or even a purist audiophile preamplifier/ DAC.

At the core of the m902 is a meticulously designed high current trans-impedance amplifier circuitry, which drives even the lowest impedance headphones. This no compromise circuitry provides high-resolution and low-level ambient detail. Familiar recorded material becomes at once transparent and alive, and critical details in editing and mastering become obvious and easy to manipulate.
