pre-owned NT-505-X
InquireThe NT-505-X is a class-leading 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 ES9038 Q2M (made by ESS Technology) in each of the left and right channels. This model achieves a high signal-to-noise ratio by using each DAC in mono mode. Moreover, when used as a USB DAC, its high specifications enable native playback of 22.5MHz DSD and 768kHz/32bit PCM formats. The Analog section, which is one of the keys to sound quality, includes four TEAC-HCLD2 buffer amp circuits that allow different drive modes, fully-balanced drive for balanced output, and parallel drive mode for unbalanced output – to achieve enhanced acoustic expression.
On the network audio side, the NT-505-X supports high-quality music subscription services, namely TIDAL, Qobuz and Roon Ready*. There’s also a built-in MQA decoder, and you will enjoy unlimited music content on the Internet thanks to its high-quality digital and Analog processing technologies.
Furthermore, you can also enjoy wireless playback from smart devices with high audio quality thanks to the high performance specifications of the DAC.
