Meticulously engineered from concept to code, the Symphonia isn’t just built for the digital era—it’s designed to elevate it. Whether you’re drawn by its striking looks or its seamless performance, this is a statement piece that bridges tradition and innovation.

Streaming & Converter

The Symphonia Streaming Amplifier stands at the forefront of high-fidelity streaming technology, powered by the advanced Audiophile Streaming Architecture (ASA) G3. Built for the modern connected world, this innovative system offers extensive source compatibility without compromising on sound quality.

Equipped with powerful network boards, the Symphonia effortlessly processes audio via Wi-Fi, LAN, and USB Master Mode. Enjoy direct access to top-tier streaming services like Tidal, Qobuz, and Deezer, as well as ultra-high-resolution local network playback up to 384/32 HD and native DSD 256.

Support for mobile device streaming through Connect or AirPlay (certification pending) ensures a seamless experience, while aptX HD Bluetooth delivers uncompressed FLAC playback—perfect for those who value both convenience and high-fidelity audio.

What truly sets the ASA G3 apart is its native DSD handling. Instead of converting DSD files through typical digital processing steps, it streams them directly to a True 1-Bit Converter, preserving every nuance of the original bitstream for a remarkably pure listening experience.

The result? A streaming amplifier that brings together the best of both worlds: advanced connectivity and uncompromising sound quality.

Streaming & Converter

The Symphonia Streaming Amplifier sets a new standard in digital audio conversion, featuring separate, dedicated converters for both PCM and DSD formats—each meticulously engineered to preserve the full integrity of your music.

Unlike traditional designs that convert DSD into PCM, the Symphonia handles DSD playback natively via its innovative True 1-Bit Converter. This ensures a direct 1-bit data stream with no unnecessary conversions, delivering audio in its purest, most authentic form. Paired with advanced Path Separation Technology, the result is flawless playback and uncompromised sonic clarity.

For PCM signals, a refined version of the renowned Double Differential Converter is used, offering remarkable tonal accuracy. This circuitry effectively neutralizes distortion and non-linearities, achieving exceptional linearity, dynamic range, and virtually zero harmonic distortion.

To enhance personalization, the Symphonia also provides adjustable algorithms for its PCM converter, allowing listeners to fine-tune their audio experience to match their unique preferences—without compromising fidelity.

Whether you’re listening to native DSD or high-resolution PCM, the Symphonia delivers a deeply engaging and customizable sound experience for even the most discerning ears.

Power Supply

While traditional switch-mode power supplies are known for their efficiency, they often introduce electrical interference that can degrade audio performance. The Symphonia Streaming Amplifier takes a radically different approach with its advanced High-Frequency Sine Power Supply—engineered to deliver clean, consistent energy with zero compromise on sound quality.

Operating at more than twice the frequency of standard power supplies, this innovative design uses a pure sine wave to significantly reduce interference. The result is a quieter power environment that preserves every nuance of your music.

At the heart of this breakthrough are ultra-responsive capacitors capable of recharging 100,000 times per second—over 2,000 times faster than conventional systems. This allows for instantaneous energy delivery during demanding signal peaks, ensuring the amplifier performs at its best even under extreme dynamic loads.

Built for long-term reliability, these robust “hard” power supplies maintain rock-solid voltage stability, enabling the amplifier to deliver consistent performance across all listening scenarios. It’s a cutting-edge solution that redefines how power should support high-fidelity sound.

Power Amplifier

The Symphonia Streaming Amplifier features state-of-the-art Class-D amplification powered by PURIFI Eigentakt™ technology—developed by a leading Danish audio innovator known for pushing the boundaries of performance. This cutting-edge platform is widely regarded as one of the most advanced solutions available today, designed to overcome the traditional drawbacks of digital amplification.

Where older Class-D designs often struggled with load dependency, signal distortion, and phase noise—especially at higher output levels—PURIFI Eigentakt™ technology delivers ultra-clean, stable sound across the full dynamic range. The result is a smooth, transparent audio performance that retains musical detail and impact, even during complex or high-energy passages.

Complementing this powerful engine is the built-in Intelligent Safe Control (ISC) system, which actively monitors amplifier conditions in real-time. Should performance thresholds be exceeded, the ISC intervenes to maintain optimal operation—ensuring long-term stability and consistent listening enjoyment.

With this level of innovation, the Symphonia doesn’t just meet expectations for Class-D amplification—it redefines them.

Connections & T+A DASS

Designed to be the centerpiece of any high-end audio setup, the Symphonia Streaming Amplifier offers exceptional connectivity and integration flexibility. With two digital inputs, two analog inputs, two USB ports, and an HDMI interface, it connects effortlessly to nearly any modern or classic source. An integrated phono stage ensures vinyl enthusiasts can enjoy the warmth of analog with stunning fidelity.

Need to expand your system? A dedicated preamp output and subwoofer connection make it easy to incorporate the Symphonia into larger setups, blending seamlessly with existing components for a richer, fuller soundstage.

Beyond its broad compatibility, the Symphonia is engineered to deliver clean, uncompromised performance. Analog signals are particularly susceptible to digital interference, which is why this amplifier features a specialized Digital-Analog Separation System. Using high-speed Silicon Labs isolators, the system establishes full galvanic separation between digital and analog circuits—safeguarding signal purity at every stage.

To further protect signal integrity, separate power supplies are used for each domain, ensuring that analog audio remains untouched and uncolored—just as the artist intended.

The result? A meticulously crafted command center that unites your entire music ecosystem with clarity, depth, and high-fidelity precision.
