This sophisticated platform enables access to leading streaming services such as Tidal and Qobuz. With T+A’s third-generation streaming client, the unit supports high-resolution PCM streaming up to 192/32 (HD) and DSD playback up to DSD256 for locally stored files.

Built for convenience as well as sound quality, the streaming client operates seamlessly in the background, making it easy to access and manage streaming services. Support for technologies like Apple AirPlay 2 and aptX HD helps overcome common mobile transmission limitations, enabling the streaming of uncompressed FLAC audio while maintaining excellent sound integrity.

In addition to online streaming and internet radio, the PSD 3100 HV also supports FM, FM-HD, and DAB+ radio, offering reliable reception and impressive audio fidelity. Its advanced digital demodulation and stereo decoding technologies, combined with high signal sensitivity, help ensure clear and stable playback—even from weaker broadcast signals.

Pre-Amplifier & Headphone Performance

The PSD 3100 HV from T+A is designed to perform as a high-end pre-amplifier at the center of a premium audio system. Its Class-A pre-amplifier stage, built using T+A’s HV discrete technology, is engineered for exceptional signal purity and dynamic performance.

Precise control is provided through a relay-controlled volume system, along with balance adjustment, loudness compensation, and switchable tone controls—allowing listeners to tailor playback to their preferences while maintaining audio integrity.

The unit also features advanced double-mono output stages, delivering clean and powerful signals through both XLR and RCA connections for seamless pairing with external power amplifiers or active speakers.

For headphone listening, the PSD 3100 HV includes a high-performance 4.4 mm balanced Pentaconn output, capable of driving dynamic headphones with excellent voltage stability and consistent current delivery—resulting in detailed, controlled, and highly engaging sound.

Comprehensive Digital Connectivity

The PSD 3100 HV from T+A is designed to accommodate a wide variety of modern digital audio sources, making it a versatile centerpiece for advanced audio systems. It includes professional-grade AES/EBU, BNC, optical, and coaxial SPDIF inputs, along with two HDMI inputs and one HDMI output, allowing convenient connection to devices such as set-top boxes, disc players, and external storage sources.

A dedicated T+A IPA-LINK interface provides seamless integration with the T+A PDT 3100 HV SACD Player, enabling efficient communication between components. The SPDIF inputs also allow playback of SACD file formats, expanding compatibility with high-quality digital music collections.

For computer-based audio, the USB-B input—powered by a Thesycon USB interface—supports ultra-high-resolution audio formats, including DSD up to DSD512 and PCM up to 768 kHz, offering exceptional flexibility for high-resolution digital playback.

Path Separation Technology for Superior Sound

A standout feature of the PSD 3100 HV from T+A is its advanced Path Separation Technology, developed to preserve the purity and detail of every recording. Instead of relying on a single converter for multiple digital formats—as is common in many designs—this approach uses dedicated conversion paths for different audio formats, helping maintain optimal signal integrity.

For PCM playback, the system employs a sophisticated double-differential, quadruple converter architecture capable of handling resolutions up to 32-bit / 768 kHz, delivering exceptional clarity and dynamic range.

For DSD audio, a specialized True 1-bit DSD converter is used, supporting formats up to DSD512 (24.6 MHz). By processing PCM and DSD signals separately, the PSD 3100 HV is able to reproduce each format using the most appropriate conversion method—resulting in precise, highly detailed sound that reflects the nuances of the original performance.

Advanced Converters & Precision Filtering

The PSD 3100 HV from T+A incorporates highly sophisticated digital conversion technology designed to deliver exceptional audio performance across a wide range of formats.

For PCM playback, the unit features a quadruple converter architecture built around eight 32-bit chips from Texas Instruments’s renowned Burr‑Brown audio line. This double-symmetrical design helps achieve impressive resolution, wide dynamic range, and extremely low distortion—even during complex musical passages.

A powerful 56-bit signal processor manages several oversampling algorithms, giving users the flexibility to adjust aspects such as timing accuracy and frequency response to match their listening preferences. Complementing this system are T+A’s proprietary Bezier filters, engineered to maintain precise timing while minimizing unwanted oscillations in the analog signal.

For DSD playback, the unit utilizes T+A’s True 1-Bit DSD converter, which processes DSD data in its native format rather than converting it to PCM. This approach preserves the distinctive sonic character of DSD recordings and allows compatible high-resolution files to be reproduced with remarkable accuracy and detail.
