The premium PRÉLUDE stereo amplifier line has been designed to meet your every musical requirement.
Having the same compact and elegant design as our SOPRANO monoblock line and available with or without integrated DAC,
the Prelude amplifiers will smoothly harmonize with your interior decoration thanks to their endless, bespoke colour options.
Beautifully curved and surrounded by an anodized aluminium bezel, the PRÉLUDE stereo amplifier’s optics, showing APURNA™’s symbolic « ice crystal » screen printed onto the acrylic glass, are exquisite.
The attractive design of the PRÉLUDE 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 technological masterpieces of an incomparable appeal are delivered inside their dedicated case.
* Only for integrated amplifiers
Model shown with integrated preamp in "PREAMP OUT" version
The connectors on all our amplifiers have been selected for their technical excellence, and are gold-plated.
