• Supports MQA decoder and music subscription services (TIDAL and Qobuz) and is Roon-ready
• DSD128 (5.6MHz) and PCM 192kHz/24-bit Network streaming from NAS/PC
• 5 types of PCM digital filters and 2 types of DSD digital filters
• Up-conversion up to 24.5MHz DSD and 384kHz/32-bit PCM
• Dual onboard clocks for 44.1kHz and 48kHz frequencies, and 10MHz external clock input
• Bluetooth® receiver supporting LDAC™ and Qualcomm® aptX™ HD
• TEAC-HCLD output buffer circuit and TEAC-QVCS volume control for high-quality sound
• “Bulk Pet” USB transfer technology, with four transfer modes to vary sound character *1
• Free TEAC HR Audio Player and TEAC HR Streamer app

 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.

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 analogue 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 analogue processing technologies.
 
 In addition to a wide range of digital and analogue 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.

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.

High-performance VERITA AK4497 DACs supporting DSD512 and PCM32/768
 The NT-505 employs the latest VERITA AK4497 (developed by Asahi Kasei Microdevices) on each of the left and right channels. It is a highly-regarded high-end audio DAC, and supports DSD512 (22.5MHz) and 768kHz/32-bit PCM formats, achieving industry-leading ultra low distortion levels. OSRD (Over-sampling Ratio Doubler) technology, meanwhile, significantly reduces out-of-band noise. As a result, the NT-505 has the refinement necessary to make the most of Hi-Res formats, successfully processing information that lies outside the audible range.

Dual monaural circuit design and fully-balanced design
 A dual monaural circuit configuration is used throughout, from the power supply (including power transformers), to the D/A converters in the digital section and the analogue output stage. From the high-performance VERITA AK4497 D/A converters to the massive toroidal-core power transformers, each element is configured for single channel processing. This prevents mutual interference effects while reproducing a rich acoustic expressiveness.
 In addition, the analogue audio signals of both the left and right channels are processed in full balanced mode soon after the D/A converters all the way to the output terminal, contributing to an improved S/N ratio and extended dynamic range. This allows the fantastic sense of air that Hi-Res formats possess to be processed and conveyed without any losses.
