opus amplifiers 



Opus is wrought CNC from a single block of aluminium



Attention to detail means appearence matters too. Like a sculpture,  Opus  is created from a single block of matter, carved for hours through an extremely complex and expensive process. This isn't however a merely an eye-catching solution; chassis has been indeed in-house engineered and designed to provide the very best heat dissipation rate related to the size, allowing to push the final stage to performances which are unthinkable with other solutions.
As music lovers, what really matter is under the hood: endelss weeks have been spent in testing the behaviours and interactions between several sets of components. Opus is, on any point of view, the extremization of our firm convinction that beside electrical values and specs, any capacitor, or transistors, or mosfet, or even power transformer ferrite core, is different one from another from a different brand. Combining the right things testing all the interactions among any component inside the PCB is indeed the most stressing, time-taking, yet rewarding task on our engineer's skilled hands.
The result is a true thoroughbred duo for music lovers par excellence: Opus I for its detail given by a Class A polarization, Opus II for its balance and control on any load. Their sound will move you at a point you will not want to stop to listen to music. Rest assured a shiver along your back will accompany all your listenings.

Design inspirations


Theater entrance stairs / Mounting screwhole design

Perfectly integrated and easily accessible screwholes for mounting the amplifier are inspired to the stairs at the entrance of the theater, as a prelude to a unique and fully immersive musical experience.

Heatsink / Keyboard

The concert is about to begin and the excitement is growing. Lights on, curtains open, the amplifier heatsink is already hot, the piano is waiting on the stage.

Pianist / Logo playing

Here comes the musician, first hand is already on those black and white keys about to give the start, anyone is looking forward for it.



Technology


Made of two, completely separated, mono amplifiers, laid down inside a unique chassis. The concept is very easy: keep everything as simple as possible in order to preserve the sound signal going through the device.

Power supply

The power supply and amplification stages are buffered with multiple and large capacitors. Only carefully selected components, a very precise component location combined with large and short signal tracks are part of the secret of these powerful amplifiers.

Straight and wireless PCB

Straight circuital configuration, sound signal path completely wireless (wires used only for protection LED module), allows to reach timbre performance and spatial reconstruction of the played musical event, suitable to the class of the device.

Gold plated brass connectors

Speakers and power connectors, including the remote, are a result of tooling of brass blocks which go throught a 24K gold plating process to improve the electric conducivity on wires contact point.

3 protections

The Thermal protection prevents the amplifier from exceeding 95°C, in case of over-heating normal operations may continue only after a temperature decrease of 10°C. The Speaker protection is enabled when a mosfet fails and the Overload protection prevents from a wrong impedance load connected on the output.

Character and personality, make out of this amplifier something
special and unique, an esoteric and intriguing mixture.

Testing Procedure

01. Stress test

Every Opus amplifier is wired to pink noise generator on the input
and resistive load on the output for 6 hours continuously.

02. Listening test

On this stage every Opus amplifier is wired to directly to speakers
and play music for another 6 hours.

Desiderio

Desiderio is the italian word for "Desire" and represents our desire to conjugate power and high quality in one amplifier. A mirror to reflect our philosophy, like a sculpture or a painting is the tangible representation of the artist’s dreams and wishes, this device is the fulfilling of our own desire, with no compromise.
