With a width of 29 cm, the network reader / TEAC NT-505 conversion unit is based on a double AKM Verita AK4497 DAC with Velvet Sound architecture, which is characterized by its ability to deliver a high current intensity. The dual mono construction extends to the power stage with dual toroidal transformer, a DSD 22.5MHz compatible USB port and 32 bit / 768 kHz PCM, separate Master Clock for 44.1 / 48 kHz signals, access Spotify Connect, Tidal and Qobuz , Roon support, high current headphone stage, RCA / XLR outputs, aptX LDAC Bluetooth module and BNC input. The BNC connector on the back, however, offers the interface for connection to the CG-10M external generator.

The USB Type B port is asynchronous and accepts DSD signals up to 22.5 MHz and LPCM 32 bit / 768 kHz, while the A-type USB port is compatible with 192 kHz and 5.6 MHz DSD files saved on HD even with NTFS formatting.

The NT-505 reader supports WAV, FLAC / ALAC and Ogg Vorbis files up to 24 bit / 192 kHz, as well as MP3, AAC and WMA. The Ethernet connection supports the DLNA protocol and provides access to the aforementioned network services Spotify Connect, Tidal, Qobuz and Roon.

The declared characteristics of the headphone stage, give it capable of delivering 2x500mW on impedances between 16 and 600 Ω. Two additional S / PDIF inputs are available, one of which is electric and one switchable coax / Toslink, while the outputs are split on RCA / XLR terminals. Four digital filters, divided equally between PCM and DSD, allow you to customize the sound output. Last but not least, there is the TEAC HR Streamer app for Android / iOS smartphones and an LDAC compatible aptX Bluetooth module.

The presence of a line input allows to use the NT-505 also as a simple preamplifier.
