T+A SDX 3100 HV Reference Streaming DAC / Preamplifier

New

The SDX 3100 HV is a milestone, not simply because it comes from a legacy of firsts, but because of what it represents. It is proof of what becomes possible when you cease to accept the status quo of complexity and move towards integration. It is more than a component; it is the destination. It is where the search for the ultimate source ends.

T+A SDX 3100 HV Reference Streaming DAC / Preamplifier

The T+A SDX 3100 HV is far more than a streaming DAC or preamplifier—it is designed as the ultimate digital and analog control center for a truly reference-level audio system. Engineered in Herford, Germany, it brings together cutting-edge digital conversion, audiophile streaming, a sophisticated preamplifier, and a high-performance headphone amplifier in one uncompromising component.

At its heart is T+A’s third-generation Audiophile Streaming Architecture (ASA G3), providing effortless access to high-resolution music from services such as TIDAL, Qobuz, and Deezer, as well as local network files and mobile devices. The SDX 3100 HV takes digital playback to an exceptional level with its T+A True 1-Bit converter, capable of native DSD processing up to DSD 1024 and PCM processing up to 32-bit/768 kHz.

Its advanced De-Jitter Masterclock technology eliminates unwanted timing errors, while the Path Separation Technology keeps DSD and PCM signals on dedicated processing paths for maximum purity. Combined with a fully discrete, double-mono preamplifier, pure Class A headphone amplifier, extensive analog connectivity, and a precision-engineered aluminum chassis, the SDX 3100 HV is built for listeners who refuse to compromise.

Whether you primarily stream high-resolution music, play local DSD files, connect traditional analog sources, or demand the finest possible headphone experience, the SDX 3100 HV brings extraordinary flexibility without sacrificing sonic performance. It is a component designed to become the heart of your system—and potentially the last source component you will ever need.

Reference-Grade Double-Mono Preamplifier

The SDX 3100 HV incorporates a sophisticated Double Mono, fully symmetrical preamplifier built with discrete components and T+A’s proprietary HV technology. The analog section is galvanically isolated from the digital domain to minimize interference, while precision relay-controlled volume regulation provides exceptionally accurate channel matching—even at very low listening levels.

Premium Construction with Analog Connectivity

The SDX 3100 HV is engineered as a serious long-term reference component, using a solid, non-magnetic aluminum chassis with precision-milled internal partitions that isolate sensitive circuit sections from interference. Its extensive balanced analog connectivity also allows it to integrate with both modern digital equipment and traditional analog sources, with an optional HV phono module available for MM or MC turntables.
