    SOPRANO

     

    The SOPRANO monoblock amplifiers comprise our complete technical expertise, for the highest level of sound performances.

     

    Moreover, they preserve APURNA™’s characteristic compact and sleek design.

    A vast choice of colours available, either in lacquer finish or in full grain leather, allow an effortless coordination with your interior decoration.

     

    Beautifully curved and surrounded by an anodized aluminium bezel, the amplifier’s optics, showing APURNA™’s symbolic « ice crystal » screen printed onto the acrylic glass, are exquisite.

    FINISHES

    The lacquer colours of the SOPRANO amplifiers can be selected from the innumerable RAL colour chart references, available in matte, gloss or satin finish. 

    The “Full Grain Leather” finishes also have various colour possibilities.

      CONTROL MODULES

      The irresistible aesthetics of the SOPRANO collection’s « OCTOGON » Control Modules* perfectly match the iconic shape of the APURNA™ amplifier collections.

       

      They function via “RF” (radio frequency) connection, controlling the APURNA™ amplifiers remotely, regardless of their orientation.

       

      The Control Modules include volume display by means of the “sources” LEDs and allow to vary or even turn off the optics when the amplifiers are switched on.

       

      These ever-elegant technological masterpieces are delivered inside their dedicated case.
