There has never been an entry-level integrated amplifier with the build quality, finish, and sound of the ROMA 753AC. At first glance, this extraordinary amplifier is simply breathtaking. This high-performance amplifier brings out the best in the other components in your system. Created by those obsessed with high-quality sound and for those who love good music, the result is 50 watts of pure pentode power per channel, achieved thanks to a pair of 12AU7 input/driver tubes and a pair of EL34/6CA7 power tubes in a push-pull configuration, for detailed, delicate, and dynamic sound.
FEATURES
DC-powered tube heater. - All tubes except the EL34 are equipped with DC-stabilized heater circuits to reduce hum to a nearly inaudible level.
Output Transformer - The output transformer uses a high-quality ferrosilicon for superb frequency reproduction and amplitude. With this newly developed custom output transformer, we are able to achieve extremely delicate and precise sound reproduction, faithful to the original recording.
Mechanical Chassis Structure:
The power supply and output transformers are housed in an extremely rigid structure that prevents the unit from experiencing unwanted vibration, further helping to reduce tube noise.
Remote Control - With soft-touch buttons, perfectly in harmony with the aesthetics of the "ROMA" series. Allows you to control volume, mute, and source selection.
Feet - Four aluminum feet with durable rubber inserts. These rubber feet were chosen to minimize amplifier vibrations, isolating it from its surroundings.
Professional gold-plated binding posts for a seamless, oxidation-free connection, further enhancing sound refinement.
Gold-plated ceramic sockets for a seamless, oxidation-free connection, further enhancing sound refinement.
Components - The Roma 753AC's components have been selected with the utmost care. Only the best available components were considered, and all underwent an exhaustive analysis of their sonic impact before final selection.
Selected Tubes - All tubes used are selected after a two-stage warm-up. A fully computerized machine controls the process and, at the end, selects the perfect tubes which are then matched to achieve perfect balance.
