Synthesis Roma 510AC Signature aluminium titan integrated tube amplifier

The Italian manufacturer Synthesis is adding an enhanced version of its popular and well-loved ROMA 510AC integrated amplifier to its range, which bears the suffix ‘Signature’ in its name.

The latest version of the amplifier features several enhancements that increase the unit’s versatility and improve its sound quality. Among the former are: XLR inputs and a high-quality phono preamplifier compatible with MM/MC cartridges, whilst the precisely shielded toroidal transformer used in the power supply undoubtedly has a significant impact on the clarity of the sound. The input stage of the MM and MC phono preamplifier utilises a low-noise operational amplifier with a separate, adjustable power supply, equipped with a sophisticated filtering circuit that ensures the reduction of interference and noise. The toroidal power transformer, with its triple-layer shielding, delivers an unexpected boost in the unit’s performance. The overall sound is dynamic, and the amplifier is compatible with any speaker. The high output power of 2 x 80W is achieved using: a dual 12AX7 triode at the input, a 12BH7 tube acting as a phase splitter, and a pair of KT88 power tubes in a push-pull configuration operating in pentode mode at the output. As a result, those that best match the reference parameters are selected and then matched in pairs to achieve perfect stereo balance.

FEATURES

DC Powered tube heater
All tubes, except KT88, 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 original recording.

Power transformer
Over size shielded power transformer for reduce the interference.

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 510AC Signature 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.
