The Grace Designs m903 is a stereo reference headphone amplifier and monitoring controller housed in a sleek 1U half-rack enclosure. The m903 accommodates these different sources with rear panel XLR and RCA jacks, and both +4dBu and -10dBV sources are easily managed. A pair of stereo TRS outputs allow two pairs of headphones to be driven by the m903. AES3, S/PDIF, and optical digital sources are accepted via rear-panel XLR, RCA and TOSlink connectors respectively. Plus, there's a USB port allows you to pump your favorite pleasure-listening tunes through the m903 for a true audiophile listening experience.
