Symphonia Streaming Integrated Amplifier

The Symphonia
With this streaming amplifier, T+A is paying homage to nearly 50 years of "Engineering Emotion". Breathing life into the claim “The Future of Retro” this device is both a bold look to the future of audio as well as a nod to the generations of T+A engineers, designers and craftspeople past and present whose ideas and hands have helped shape some of their most iconic devices, be it in terms of technology, looks or aesthetics. Merging the very latest in streaming technology, digital to analogue conversion and amplification with an industrial design that celebrates T+A's  most beloved past products, from phased front panels to hand assembled VU-metres, the Symphonia is retro in the very best sense of the term: grounded in the past without just rehashing it yet also embracing the future without forgetting its roots. Symphonia combines the past and modernity on the quest to be a sonic companion for eternity.

Concept
Like every T+A product, the Symphonia was crafted with a bold vision: to deliver a universally capable "one-box system" which redefines what's possible. With an extensive array of sources, Symphonia offers near-limitless playback options. Advanced DSD and PCM converters transform digital signals into rich, analogue soundscapes of breathtaking quality, while the built-in amplifiers (boasting 250WPC!) bring your music to life with remarkable clarity and depth. At the heart of Symphonia lies the third generation of T+A's Audiophile Streaming Architecture (ASA G3). This cutting-edge combination of hardware and software ensures effortless access to streaming services, USB sources, and a seamless, intuitive experience with Connect Services, allowing you to play music directly from some of your favourite mobile apps.

Design
Measuring just under 4" tall and an almost square 15" Wide by 13.5"deep, Symphonia is designed to be at home virtually anywhere. In celebration of nearly fifty years of T+A design tradition, Symphonia's proportions pay homage to T+A's first preamplifiers from the mid-1980s. Beveled edges on the front panel are a nod to the timeless elegance of T+A's iconic R-Series; a line of producets continuously refined since the 1990s. The control elements and VU meters evoke the innovative spirit of the modern Series 200. With only a few thoughtfully placed buttons on its graceful front panel the aesthetic is simple and elegant. Rotary push controls offer swift, intuitive access to every function and setting.

From the first stroke of the pen on a blank sheet of paper to its cutting-edge hardware design, all the way to the hundreds of thousands of lines in the software code, Symphonia was designed to keep pace with the digital age and to elevate the opportunities it brings.

In the Symphonia, T+A relies on in-house customizations of the Class-D amplifiers powered by the groundbreaking PURIFI Eigentakt™ technology. Developed by the pioneering Danish technology company, this platform stands as nothing less than the world's leading concept for Class-D amplification, overcoming the limitations that have long held back other digital amplifiers through a meticulous and innovative approach.

In the past, digital amplifiers were often constrained by high load dependency, signal distortion, phase noise, and increased harmonic distortion at high power levels. The amplifier technology integrated into the Symphonia not only eliminates these challenges but redefines performance.

Keeping an eye on potentially untamed power is T+A's Intelligent Safe Control (ISC) which regulates the system in case any of a set of pre-defined parameters exceed their operating limits.

A T+A streaming integrated amplifier is designed to be the central hub of your musical home. That’s why T+A equipped the Symphonia with the range of connections needed for truly universal use. With two digital, two analog, and two USB inputs, as well as an HDMI interface, the Symphonia seamlessly connects to virtually any source. Meanwhile, an integrated phono module ensures that even the most classic of sources benefits from the Symphonia’s remarkable sound performance. A preamp output and subwoofer connection allow the Symphonia to integrate harmoniously into existing systems, making it a versatile and indispensable part of any audio setup. The Symphonia isn’t just another device - it’s a carefully crafted command centre for all your musical needs, offering connection, clarity, and uncompromising quality.

All analog signal paths are inherently sensitive to digital interference. In a receiver designed to meet the highest expectations, a deliberate and meticulous separation of these two domains is the cornerstone of sonic perfection. Only in this way can the analog music signal remain as pure and unaltered as the artist captured it in the studio.

This is why T+A developed the Digital-Analog Separation System - using ultra-fast Silicon Labs isolators, we establish a galvanic separation between the digital and analog sections of the device, effectively shielding the analog signal from disruptive interference. To ensure that this separation is upheld throughout the entire signal path, T+A has even gone as far as to isolate the power supplies for the digital and analog domains.
