The NT-505-X is a flagship dual monaural USB DAC with versatile network playback capabilities. It successfully incorporates the latest network technologies, along with TEAC’s decades of accumulated audio design experience, in an attractive package with an A4-sized footprint. The dual mono structure processes stereo signals with higher purity, and the D/A converter section uses one ES9038Q2M (made by ESS Technology) in each of the left and right channels.
