Professionals and audiophiles alike will be floored by the high-performance 24-bit/192kHz DAC, which includes a unique s-Lock dual-stage PLL (Phase Lock Loop) for extremely low intrinsic jitter and rock-solid digital performance. A full set of analog and digital inputs are available, all of which are selectable via a front panel rotary switch. At the core of the m902 is meticulously designed, high-current transimpedance amplifier circuitry which effortlessly drives even the lowest impedance headphones. Familiar recorded material becomes at once transparent and alive, and critical details in editing and mastering become obvious and easy to manipulate.
