Roma 753AC
50W Integrated Stereo Tube Amplifier
There has never been an introductory integrated amplifier with the fit, finish and sound of the ROMA 753AC. At first glance, this stunning amp simply takes your breath away. This high performance amplifiers brings out the best of other components in the system. Created by those obsessed with great sound and for those who love great music.The result is 50 watts of pure pentode output per channel built around a pair of 12AU7 on input/driver tubes and a pair of EL34/6CA7 power tubes in push-pull configuration for a detailed, delicate and dynamic sound.
FEATURES
- DC Powered tube heater
All tubes, except EL34, have DC stabilised heater circuits to reduce hum noise to a near in-audible minimum. - Output transformer
The Output transformer uses a Hi-Grade lron-Silicon for superb frequency reproduction & width. With this newly designed custom output transformer we are able to achieving a highly delicate & precise sound reproduction faithful to the originai recording. - Mechanical chassis construction
The power supply & output transformers are held by an extremely rigid structure that keeps the unit free from unwanted vibrations which further helps reduce unwanted noise to the tubes. - Remote control
It has a soft button design, perfectly matching the aesthetics for the "ROMA" series. It controls volume,mute and sources selection. - Feet
Four aluminium feet with an insert of strong rubber. These rubber feet has been chosen to minimise vibrations of the amplifier in isolation from its surroundings. - Binding posts
Gold plated professional binding posts for a continued oxidisation free connection further improve sound refinement. - Sockets
Gold plated ceramic sockets for a continued oxidisation free connection further improve sound refinement. - Components
Components for the Roma 753AC have been selected with great care throughout. Only the best available components are considered & all must undergo an exhaustive analysis of their sonic influence prior to final selection. - Selected tubes
All tubes used are selected after 2 stage warm up. A fully computer monitored machine controls the process & at the end of this, selects the perfect tubes which are then matched for a perfect balance.
