Grace Design m902 (Used)

Where Hi-Fi meets Hi-End. Simply plug in your favorite headphones, cue up your best reference tracks and get ready to hear, literally, what you’ve been missing - courtesy of the m902 reference headphone amplifier. At the core of the m902 is our audiophile, high-current transimpedance amplifier circuitry, which effortlessly drives even the lowest impedance headphones and provides the high-resolution and low-level ambient detail for which all our products are famous. This circuitry makes familiar recorded material become at once transparent and alive, while critical details in editing and mastering become obvious and easy to manipulate. Professionals and audiophiles alike are continually floored by the m902’s high performance 24bit/192kHz DAC, which includes our unique s-Lock™ dual stage PLL (Phase Lock Loop) for extremely low intrinsic jitter and rock solid digital performance.Features:
