Synthesis Roma 753AC Valve Integrated Amplifier

Roma 753AC Integrated Stereo Tube Amplifier: Unparalleled Craftsmanship and Sonic Excellence

The Roma 753AC is an exquisitely designed 50W integrated stereo tube amplifier, delivering outstanding sonic performance and unparalleled build quality. At its core, this amplifier is meticulously crafted to bring out the best from any connected audio components, ensuring listeners enjoy music with clarity, depth, and emotion. Built for audiophiles and music lovers alike, the Roma 753AC exemplifies precision and elegance in its form and function.

Audiophile-Grade Performance

The Roma 753AC produces 50 watts per channel of pentode output, utilizing 12AU7 input and driver tubes, alongside EL34/6CA7 power tubes in a push-pull configuration. This carefully designed layout allows for remarkable sound detail, delicacy, and dynamic range. Whether playing classical music or hard rock, the amplifier’s detailed reproduction captures the essence of every musical nuance.

The sound stage is expansive, covering a frequency response from 20Hz to 20kHz with minimal distortion (<1% THD). Whether you’re an audiophile seeking transparency in high frequencies or rich low-end warmth, the Roma 753AC promises consistent, distortion-free performance across the spectrum. With a signal-to-noise ratio greater than 90dB, the sound remains pristine, even at high volumes.

Innovative Tube Heating and Transformer Technology

Central to its performance, the Roma 753AC features DC-powered tube heaters, which dramatically reduce hum and noise—enabling an ultra-quiet operation. The output transformer, made from high-grade iron-silicon, ensures superb frequency reproduction and precise sound accuracy. This innovative design results in a clean, true-to-life musical experience, faithful to the original recording.

The mechanical chassis construction is engineered to eliminate unwanted vibrations that can affect tube performance. By isolating the power supply and transformers, the Roma 753AC further reduces noise and distortion, ensuring that listeners are only immersed in pure sound.

Precision Engineering for Seamless Connectivity

Designed for seamless integration with high-fidelity systems, the Roma 753AC includes five line inputs for versatility. The gold-plated professional binding posts and ceramic sockets ensure long-lasting, oxidation-free connections, maintaining the purity of the audio signal. The inclusion of a variable pre-out provides flexibility for those who may want to connect the amplifier to an external power amp or subwoofer, expanding the possibilities for custom sound setups.

Each component, from resistors to capacitors, is carefully selected for its sonic characteristics, tested through a rigorous selection process to ensure optimal performance. Even the tubes undergo a two-stage warm-up and computer-monitored matching process, guaranteeing perfect balance and long-lasting reliability.

Remote Control and Ergonomic Design

A perfect blend of classic tube aesthetics and modern convenience, the Roma 753AC includes an anodized black aluminium remote control. This soft-button remote controls essential functions like volume, input selection, and mute, while maintaining the amplifier's sleek and timeless aesthetic. The infrared transmission uses the reliable RC5 protocol, ensuring responsive control from across the room.

The amplifier is housed in a rigid chassis, supported by four aluminium feet with rubber inserts, designed to isolate the unit from external vibrations. These feet, alongside the durable, high-quality construction of the body, make the Roma 753AC as functional as it is beautiful.

Optimized Tube Configuration for Refined Sound

At the heart of the Roma 753AC is its carefully calibrated tube configuration. The push-pull pentode design delivers high power and efficiency, while the manual bias setting allows users to finely tune each power tube for ultimate control over the sound output. The independent bias adjustment for each tube ensures balanced performance, extending the lifespan of the tubes while keeping the sound consistent and accurate.

This attention to tube management highlights the amplifier’s role as a high-performance piece of audio equipment, designed for those who value tonal accuracy and immersive listening.

Premium Aesthetics and Build

Available in multiple finishes, including wood, black, dark, and aluminium silver or black, the Roma 753AC offers a visual appeal as stunning as its sound. With dimensions of 410x420x210mm and weighing a substantial 25kg, it exudes a robust and premium presence, suitable for any high-end audio setup. The unit is compatible with a range of power inputs (117V, 230V, 245V at 50/60Hz), making it suitable for global use, and features gold-plated connectors that ensure lasting performance.

The Roma 753AC is a masterpiece in the realm of high-end tube amplifiers, offering exceptional sound quality, precision engineering, and an elegant design—an essential for those who appreciate music in its purest form.
