TEAC NT 505 - Roon Ready Hi-Res Streamer DAC

Rs. 165,500.00

The NT-505 is a compact and high-spec USB DAC and network player that supports the latest Hi-Res formats and online music subscription services.

Like its predecessor (the NT-503) it employs a dual monaural circuit design to process audio signals with even greater purity, with the latest VERITA AK4497 DAC chip used on each of the two channels. This improves the S/N (signal to noise) ratio by processing each channel individually in monaural mode, as well as delivering DSD512 (22.5MHz) native and 768kHz/32-bit PCM playback capabilities.

The Analog section, which is one of the keys to sound quality, includes four TEAC-HCLD 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 supports high-quality music subscription services, namely TIDAL and Qobuz, and is 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.

In addition to a wide range of digital and Analog inputs, a Bluetooth® receiver supporting LDAC™ and Qualcomm® aptX HD™ allows you to stream high-quality audio wirelessly from your smartphone to this flagship USB DAC.
