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

HIGH PERFORMANCE VERITA AK4497 DACS
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. * The AK4497 is the flagship product of the Asahi Kasei Microdevices Audio4pro™ family, which has been developed for professional audio equipment and high-end digital audio. 

DUAL-MONO AND FULLY BALANCED CIRCUIT 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 HiRes formats possess to be processed and conveyed without any losses. 

TIDAL, QOBUZ AND ROON READY
Connecting to your home network via a LAN cable, the NT-505 allows you to access Hi-Res music libraries on available music servers and computers, as well as hundreds of millions of CD-quality tracks on Internet via music subscription services like TIDAL and Qobuz. The NT-505 is also a Roon Ready product that enables Hi-Res audio streaming thanks to its high performance D/A converters. *Roon Ready is scheduled to be deployed in the near future.

MQA DECODER FOR MASTER QUALITY STREAMING
In order to achieve an analogue waveform closer to the original signal, the Teac NT-505 supports MQA decoding while also supporting high sampling rate Hi-Res formats like DSD512 and PCM32/768. The MQA decoder is a totally new technology that controls analogue waveforms with excellent precision (as fine as 5 microseconds) and it reproduces sound in a manner that is perceived to be as close as possible to the original (to human hearing). Furthermore, a high-efficiency compression algorithm makes huge Hi-Res audio files compact in size, so you will be able to enjoy Hi-Res audio sources regardless of the speed of your Internet connection.

HIGH-QUALITY WIRELESS AUDIO STREAMING VIA BLUETOOTH
In addition to conventional SBC and AAC codecs, the NT-505 also supports LDAC™ (24/96 Hi-Res audio transmission), and Qualcomm® aptX™ HD, a codec that uses 24/48 format transmission. These allow you to playback playlists on your smartphone and tablet wirelessly. 

HI-RES AUDIO PLAYBACK FROM USB FLASH DRIVE
The USB port on the front panel allows you to playback Hi-Res audio formats including DSD128 (5.6MHz) and PCM 24/192.

DUAL ONBOARD CLOCKS FOR 44.1K AND 48KHZ AND AN EXTERNAL CLOCK INPUT
Instead of referencing to an unstable and noisy PC clock during USB audio playback, a more accurate and on-board clock is generated by a high-precision, low phase-noise, audio-grade crystal oscillator for USB asynchronous transfer mode. The NT-505 accommodates two on-board clocks exclusively for 44.1kHz and 48kHz sampling frequencies and applies the appropriate one to incoming digital signals – those that are multiples of 44.1k or 48k – to reproduce identical sound to the original by eliminating jitter effects on the audio signal. In addition, an external 10MHz clock input is also provided, to synchronise with an even higher precision master clock generator, such as the TEAC CG-10M, for yet further upgraded audio playback with excellent sound quality. 

UPSAMPLING TO 384KHZ/32-BIT PCB AND 24.5MHZ DSD
 Employing RDOT-NEO (Refined Digital Output Technology NEO), a fluency algorithm that renders digital audio signals smoothly, the NT-505 up-converts PCM digital signals up to 384kHz/32-bit PCM and 24.5MHz DSD. With the up-conversion function activated, you will hear an improvement in quality, even with music that you are familiar with.
