TEAC NT-505-X
The 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.
Supports Spotify Connect, TIDAL, Qobuz, and TuneIn
By connecting the unit to a home network using a LAN cable, music files saved on NAS music servers and computers can be accessed and played back. In addition, this unit also supports the Spotify, TIDAL, and Qobuz subscription Internet music streaming services. These enable listening to tens of millions of lossless CD-quality (44.1kHz/16bit) music tracks.
7 types of PCM digital filters
There are seven types of PCM digital filters, allowing you to apply the filter that best matches the file format or type of music you're listening to. The filter can be changed at the touch of a button on the remote control, allowing you to enjoy the different sonic nuances of each filter.
Dual high-capacity toroidal-core power transformers
The dual monaural theme continues. Two over-sized high-capacity toroidal-core power transformers are employed in the NT-505-X, supplying stable, individual current sources for each of the left and right channels. This means neither channel will be affected by changes in the power consumption of the other during digital processing.
