Synthesis Soprano amplifier

Soprano - 12W A-Class Integrated stereo tube amplifier

Following the success of the much-celebrated NIMIS, Synthesis took on the challenge of recreating a 12W A-Class integrated stereo tube amplifier. Using a new technologies a new business development and Luigi Lorenzon’s constant pursuit of perfection, he succeded in creating an entry level amplifier that is able to satisfy even the most dedicated audiophile.

New model of stereo tube amplifiers with DAC's on board, guaranteeing exceptional sonic performance from any digital source.

Made with the finest materials & advanced technology, this series is a sophisticated blend of research & experience.

Designed without compromise far a rich sound & faithful music reproduction.

The SOPRANO provides a minimum of 12 Watts per channel, power output from a pair of EL84's in Ultra-Linear (UL) - push/pull operation.

The SOPRANO features a newly designed custom output transformer resulting in a rich sound stage but with an authority that belies its 12Wpc

FEATURES

- USB -

DAC on board 24bit for a extraordinary listening experience from computer’s file.

- Phono Stage -

Hi quality Phono stage for MM cartridges.

-SPDIF inputs (Coax and Optical) Built around a AKM chip. 24 Bit 192KHz Hi Quality DAC for an extraordinary sound result.

- Output Transformer -

The Output transformer uses a Hi-Grade iron-Silicon for superb frequency reproduction & width. With this newly designed custom output transformer unique to the Soprano we are able to achieving a highly delicate & precise sound reproduction faithful to the original 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.

- Binding Posts -

Gold plated professional binding posts for a continued oxidization free connection further improve sound refinement.

- Sockets -

Ceramic sockets for a continued oxidization free connection further improve sound refinement.

- Components -

Components for the amplifier 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.
