The ROMA 510AC is a stereo amplifier that immediately stands out for its commanding presence and extraordinary sound quality. Delivering 80 W per channel in pure pentode mode, it combines elegance, design, and performance in a single unit engineered to bring out the best in all other components of the system. At its core, the amplifier features a Push-Pull configuration with KT88/6550 power tubes, supported by a 12AX7 dual triode at the input stage and a 12BH7 as a phase splitter, working together to produce a detailed, dynamic, and refined sound, capable of reproducing music with remarkable naturalness and depth.

Attention to sound quality is evident in the tube management: all tubes, except the KT88/6550, use DC-stabilized heater circuits to minimize hum and any interference, ensuring clean and quiet listening. The output transformer is custom-designed with high-quality silicon-steel, delivering precise, delicate sound reproduction faithful to the original recording and providing an excellent frequency range. The mechanical structure is extremely rigid, with power and output transformers securely mounted to isolate the unit from unwanted vibrations, further enhancing sound clarity.

The ROMA 510AC comes with a stylish remote control with soft-touch buttons, allowing convenient adjustment of volume, mute, and source selection. The amplifier rests on four aluminum feet with robust rubber inserts, chosen to isolate the unit from its surroundings and minimize vibrations. Connections are made through gold-plated binding posts and ceramic sockets, ensuring continuous contact, resistance to oxidation, and an even more refined sound performance.

Every component in the ROMA 510AC is meticulously selected: only the best available parts are considered, each undergoing a thorough analysis of its sonic impact before final selection. The tubes are carefully matched through a computer-controlled two-stage process, ensuring perfect pairing for optimal balance and consistent, harmonious musical reproduction. The result is an amplifier designed by enthusiasts for enthusiasts, capable of transforming every listening session into an engaging, professional-level audio experience.
