SYNTHESIS ROMA 753 AC

Pre owned. In excellent condition. No visible signs of wear. Comes with remote control, original packaging, and manual.

The Synthesis Roma 753AC is a tube integrated amplifier that redefines high-fidelity standards, combining aesthetic elegance, meticulous craftsmanship, and high-level sonic performance. At first glance, it impresses with refined design and attention to detail, while in listening it reveals a musical character capable of enhancing every component in the system. Designed for those who seek the true pleasure of listening, it is born from the experience and passion of those who consider sound a form of art.

Its architecture is based on a push-pull class AB configuration, delivering 50 watts RMS per channel in pentode mode. It uses EL34/6CA7 tubes for the power stage and 12AU7/ECC82 tubes for the input and driver stages, providing an ideal combination of detail, dynamics, and natural sound. The tube heaters are DC-stabilized for all tubes except the EL34s, reducing background noise to virtually inaudible levels and ensuring a clean, stable signal.

The custom output transformer, made from high-purity silicon steel, ensures wide and linear frequency response, delivering faithful and transparent sound reproduction. The entire mechanical structure is designed to eliminate unwanted vibrations: the power and output transformers are anchored to a rigid, massive chassis that isolates the tubes from mechanical interference. Aluminum feet with high-density rubber inserts further reduce vibration transmission, improving overall stability.

Every construction detail reflects meticulous attention to perfection: gold-plated output connectors and gold-plated ceramic sockets provide oxidation-free connections and impeccable signal transfer. All electronic components are carefully selected and undergo thorough analysis of their sonic contribution before final assembly. The tubes, central to the Synthesis philosophy, are chosen through a two-stage computer-monitored warm-up and testing process to ensure perfect matching and consistent performance.

The Roma 753AC also offers the convenience of an elegant, intuitive remote control with soft-touch buttons that perfectly match the series’ design. It allows smooth and precise control of volume, mute, and source selection. The amplifier represents the perfect synthesis of technology, aesthetics, and musical passion. It is designed for those who wish to enter the world of tube sound without compromise, capable of turning every listening session into an intimate and immersive experience, where music comes alive with warmth, transparency, and authenticity.
