- The TEAC NT-507T is a high-end network streaming transport without an internal DAC, featuring the new TEAC Network Engine G4, linear power supply, RJ45 and SFP connectivity, and WiFi 6. Designed for audiophiles, it supports up to DSD512 and Linear PCM 32 Bit and 768 kHz and works seamlessly with Roon and OpenHome.
Few brands embody the tradition of Japanese audio engineering as consistently as TEAC Corporation. With the launch of the TEAC NT-507T, the company extends its Reference 500 Series into the realm of pure network transports. This new model targets listeners who already own a high-grade external DAC and want to add a noise-free, precision digital source to their streaming setup. Its design philosophy revolves around maximum signal purity, stable power delivery, and effortless integration into modern network environments.

Design and Construction
The TEAC NT-507T follows the visual and mechanical design language of the Reference 500 Series – compact, elegant, and meticulously engineered. Its aluminum enclosure reflects a clear “form follows function” philosophy, avoiding superfluous elements that could compromise signal integrity.
TEAC deliberately omitted a display, focusing instead on a short, interference-free signal path. Even the status LEDs can be disabled for undisturbed listening. A 2,8 mm semi-floating aluminum top plate minimizes vibrations, while precision machining ensures the rigidity expected of high-end components in this class.
Technology and Architecture
At the heart of the NT-507T lies the TEAC Network Engine G4, developed specifically for high-resolution streaming up to DSD 22,5 MHz and Linear PCM 32 Bit and 768 kHz. According to TEAC, the combination of a powerful processor, generous memory architecture, and ultra-low-noise circuitry results in a remarkably natural, almost analog sonic presentation.
Power delivery is handled by a custom linear power supply with a large toroidal transformer. Four independent secondary windings provide isolated feeds for the network engine, USB output, WiFi module, and front-panel indicators, each with discrete low-feedback DC regulators to reduce crosstalk and electrical noise.
The USB Type-A output is fully isolated and features its own regulated power rail to ensure signal integrity. A digital volume control function allows volume adjustment of a connected DAC or preamplifier directly via the app – without altering the bit-perfect data stream.
Network and Streaming Capabilities
Networking on the NT-507T goes well beyond conventional solutions. Alongside a standard RJ45 Ethernet port, it offers an SFP optical port, allowing fiber-optic connection for complete galvanic isolation from network noise. For wireless operation, WiFi 6 is supported, ensuring maximum bandwidth and reliability.
Users can access a wide range of sources: Qobuz Connect, TIDAL Connect, Spotify Connect, TuneIn Internet Radio, Roon (including Roon-only mode), local NAS libraries, and directly attached USB storage. Supported file formats include FLAC, ALAC, WAV, AIFF, MQA, DSD, and Linear PCM, all up to their respective maximum resolutions.
Operation and Integration
Control is handled via the TEAC HR Streamer App, available for both Apple iOS and Google Android. Built on the OpenHome framework, the app supports gapless playback, on-device playlist management, and direct access to local and cloud-based libraries.
The NT-507T can even act as a lightweight media server: with dual USB ports (rear Type A and front Type C), it supports external flash drives, HDDs, or SSDs, making it possible to create a compact yet centralized local music library. This makes the unit highly versatile within both minimalist and complex digital systems.
Practical Use in Modern Systems
In a high-end streaming environment, the NT-507T serves as the digital hub for users who prefer to keep conversion duties in an external DAC. The separation of network transport and D/A conversion minimizes interference and gives users the flexibility to fine-tune system synergy. Whether in a dedicated listening room, studio, or living space, the NT-507T fits seamlessly into any setup designed around sonic precision and operational elegance.
Price and Availability
According to TEAC, the NT-507T will become available worldwide in December 2025 in two finishes – NT-507T-B (Black) and NT-507T-S (Silver). Official retail pricing has not yet been confirmed and is expected to be announced closer to market launch.
Conclusion – Streaming Purism Perfected
The TEAC NT-507T exemplifies the company’s enduring commitment to minimalist, performance-driven design. Focusing solely on the essentials – clean power delivery, uncompromised data handling, and seamless integration – it embodies the TEAC Reference 500 Series ethos. For discerning music lovers seeking a transparent, flexible, and future-proof network transport, the NT-507T represents a meticulously engineered centerpiece for any modern digital system.
