Synthesis Roma 510 AC Valve Amplifier [2nd hand]

Synthesis Roma 510 AC Valve Amplifier

There has never been an entry-level integrated amplifier with the build quality, finish, and sound of the ROMA 510AC. At first glance, this stunning amplifier simply takes your breath away. This high-performance amplifier brings out the very best in the other components of the system. Created by those obsessed with great sound and for those who love great music. The result is 80 watts per channel of pure pentode power, built around a 12AX7 dual triode at the input stage and a 12BH7 tube as the phase splitter, along with a pair of KT88/6550 power tubes in push-pull configuration, delivering a detailed, delicate, and dynamic sound.

FEATURES

• DC-powered tube heaters

All tubes, except the KT88, feature DC-stabilized heater circuits to reduce hum noise to an almost inaudible minimum.

• Output transformer

The output transformer uses high-grade iron-silicon material for superb frequency reproduction and bandwidth. With this newly designed custom output transformer, we are able to achieve highly delicate and precise sound reproduction, faithful to the original recording.

• Mechanical chassis construction

The power supply and output transformers are supported by an extremely rigid structure that keeps the unit free from unwanted vibrations, further helping to reduce noise affecting the tubes.

• Remote control

It features a soft-touch button design, perfectly matching the aesthetics of the “ROMA” series. It controls volume, mute, and source selection.

• Feet

Four aluminum feet with high-strength rubber inserts. The rubber has been chosen to minimize amplifier vibrations by isolating it from its surroundings.

• Binding posts

Gold-plated professional binding posts ensure a continuous oxidation-free connection and further enhance sound refinement.

• Sockets

Gold-plated ceramic sockets provide a continuous oxidation-free connection, contributing to greater sonic refinement.

• Components

Components for the Roma 510AC have been selected with great care throughout. Only the best available components are considered, and each must undergo an exhaustive analysis of its sonic influence prior to final selection.

• Selected tubes

All tubes are selected after a two-stage warm-up process. A fully computer-monitored system controls the procedure and, at the end, selects the perfect tubes, which are then matched to ensure ideal balance.
