SD 3100 HV DAC (with Optional Volume Control) By T+A HiFi

The T+A SD 3100 HV is a flagship high-end streaming DAC designed for uncompromising digital music playback. Built on the same advanced platform as the SCD 3100 HV—without the integrated pre-amplifier section—it functions as a pure, ultra-high-performance converter and network streamer for demanding audiophile systems.

Engineered to handle virtually any digital source with exceptional precision, the SD 3100 HV integrates seamlessly into the T+A HV ecosystem. It connects effortlessly to the P 3100 HV preamplifier or PA 3100 HV integrated amplifier through its high-quality analog outputs. For physical media playback, it can also be paired with the PDT 3100 HV reference disc transport for CD and SACD listening.

Convenient control is available via the F 3100 remote control or the T+A MusicNavigator app, allowing easy access to your digital music library and streaming services.

High-Performance Headphone Amplifier

Recognizing the increasing popularity of high-end headphone listening, T+A has incorporated an exceptional analog headphone amplifier into the SD 3100 HV.

Built using the company’s renowned HV technology, the amplifier operates entirely in pure Class A mode, delivering remarkable transparency, dynamics, and musical detail.

The front panel provides versatile connectivity, including:

• 6.3 mm headphone output for traditional audiophile headphones
• Balanced 4-pole Pentaconn connector for premium balanced headphone cables

This ensures compatibility with a wide range of high-end headphones while delivering reference-quality performance.

Precision Construction

Like other components in the HV series, the SD 3100 HV features a precision-machined aluminum chassis designed to eliminate the influence of ferro-magnetic materials and preserve signal purity.

Internally, the unit is carefully divided into five isolated compartments, each dedicated to specific functions:

• Digital input and motherboard section
• D/A conversion and analog output stage
• Analog power supply
• Digital power supply
• Control electronics with high-resolution display and touch-sensitive front panel controls

This meticulous internal architecture minimizes interference between circuits and helps deliver the exceptional clarity, stability, and sonic performance expected from a flagship reference component.

Future Audiophile
To be sure, this is a product intended for a very high-end audio system. When paired with similar digital components, it will make listening to music the magnificent experience all audiophiles want and expect.
