SDX 3100 HV Streaming DAC and Preamp By T+A HiFi

T+A SDX 3100 HV Reference Streaming DAC & Preamplifier

The T+A SDX 3100 HV is a reference-class streaming DAC and preamplifier designed for discerning audiophiles who demand uncompromising digital and analogue performance. Combining advanced streaming technology, dedicated PCM and DSD conversion, and a fully balanced analogue preamplifier in a single precision-engineered component, it serves as the ideal centerpiece for a world-class high-fidelity system.

Reference Streaming DAC for High-End Audio Systems

Designed as part of T+A’s renowned HV Series, the SDX 3100 HV brings together a high-resolution network streamer, dual DAC architecture, and an advanced analogue preamplifier within a robust aluminium chassis. Its modular design and premium engineering make it an excellent choice for music enthusiasts looking to build or expand a high-performance audio system for years to come.

Dedicated Signal Paths for Maximum Audio Fidelity

To preserve the integrity of every recording, the SDX 3100 HV employs completely separate signal paths for PCM and DSD audio formats. By physically isolating the digital and analogue sections, unwanted interference is minimized, resulting in greater transparency, lower noise, and exceptional musical detail.

Third-Generation Audiophile Streaming Architecture (ASA G3)

At the heart of the SDX 3100 HV is T+A’s latest Audiophile Streaming Architecture (ASA G3), delivering stable, high-resolution streaming from today’s most popular music platforms.

Supported services include:

• Amazon Music
• TIDAL
• Qobuz
• Deezer
• HighResAudio
• Apple AirPlay
• Spotify Connect
• Qobuz Connect
• TIDAL Connect

The platform also supports native high-resolution DSD playback directly from compatible network storage devices and external drives, ensuring exceptional playback quality across a wide range of digital music libraries.

Advanced Dual DAC Architecture

The SDX 3100 HV utilizes dedicated conversion technologies for each digital audio format, allowing every recording to be reproduced using the most appropriate processing method.

• Native True 1-Bit DSD Converter supporting playback up to DSD1024
• Quadruple PCM DAC featuring four high-performance 32-bit Burr-Brown converter chips
• Independent processing paths eliminate unnecessary format conversion and preserve original recording quality

This sophisticated architecture delivers outstanding clarity, natural tonal balance, and exceptional dynamic performance.

Ultra-Low Jitter Clock System

Precision timing is achieved through dual Femto-grade quartz oscillators combined with a multi-stage jitter reduction system. This advanced clock architecture minimizes digital timing errors and helps maintain accurate, stable signal reproduction for improved detail and imaging.

Fully Balanced HV Preamplifier

The integrated HV preamplifier features a fully symmetrical dual-mono design, maximizing channel separation while providing generous dynamic headroom. Precision gas-tight relays ensure accurate channel matching for consistently balanced stereo performance.

Precision Analogue Tone Controls

Unlike digital tone adjustments, the SDX 3100 HV incorporates a fully analogue tone control circuit that preserves signal purity while allowing users to fine-tune bass and treble response.

Key benefits include:

• Analogue bass and treble adjustment
• Adjustable turnover frequencies
• Independent left and right channel tuning when required
• No digital signal processing applied to the audio signal

Optional High-Performance Phono Module

For vinyl enthusiasts, the SDX 3100 HV can be equipped with an optional HV Series phono module. Available in either Moving Magnet (MM) or Moving Coil (MC) configurations, the module installs conveniently into the dedicated rear-panel slot, allowing seamless integration of high-quality turntables into your audio system.

Key Features:

• Reference Streaming DAC and analogue preamplifier
• Third-generation Audiophile Streaming Architecture (ASA G3)
• Native DSD1024 playback with dedicated True 1-Bit DSD converter
• Quadruple 32-bit Burr-Brown PCM DAC architecture
• Separate signal paths for PCM and DSD processing
