The Amplifiers for your Opera Sonora
Each Opera Sonora is accompanied by an elegant and performing amplifier, to ensure our precious natural acoustic speakers a high quality sound from the source.
Tube Amplifier
Nobsound stereo
Compromising the performance of an Opera Sonora by associating it with an unsuitable or low quality amplifier would be an unforgivable mistake.
For this reason, to accompany the loudspeakers of the Classic Line series, we have chosen the elegant Nobsound stereo tube amplifier, a hybrid model characterized by digital inputs and controls, and by an exposed tube amplifier, to guarantee a warm and satisfying sound rught from the beginning. The system provides a 100 watt active subwoofer, and features two RCA inputs on the rear panel, a front USB port and Bluetooth connectivity.

Denon Stereo Amplifier
As an alternative to the stereo tube amplifier, the Opere Sonore of the Classic Line series can be accompanied by a more modern Denon class D amplifier, capable in turn of guaranteeing a top level audio source.
We are talking about an instrument particularly suitable for those who love to interface in a smart way with music: with the Denon model it is possible to comfortably enjoy their music from CD, but also directly from a pendrive, or even, surfing the net and downloading any desired musical brand through the appropriate LAN connection.
It should also be emphasized that the Denon amplifier can also be controlled via smartphone, thanks to the dedicated app.

Mono amplifier MDI 64-12
and Cube Bass Subwoofer
The Limited Edition acoustic models stand out not only for their exclusivity, but also for their characteristic monophony.
Instead of having two distinct soundboards, in this case, there is in fact a single wooden table, accompanied by a Cube Bass Subwoofer, designed and built by Ciresa with the same philosophy as the Opere Sonore, to produce low frequencies through vibration. of harmonic wood. To complete the whole there is an amplifier designed specifically for these speakers, namely the MDI 64-12 model in class A. Designed in every detail to enhance the sound of the soundboard, this amplifier receives the audio signal from three RCA inputs, at which is added a PHONO input, with internal preamp stage, dedicated to listening to vinyl records.
