NOVA NCD 1

The NCD1 player uses Philips CD Pro 2 transport, one of the best CD modules currently available, inserted in a particular semi-rigid system, composed of a steel and wood mass suspended on anti-vibration mounting pads.
The conversion unit is developed around the top-of-the-line Analog Devices converter, the AD1955, and an upsampling circuit that raises the resolution of digital data to 24 bit/192kHz based on an Analog Devices AD1896 integrated circuit. The entire digital signal conversion system is mounted on an independent printed circuit board that can be easily removed and replaced in case of technological updates, without having to change the entire player.
Thanks to the high sampling frequency, it was possible to use a first order analog filter made up of a metal film resistor and an exceptionally high quality silver mica capacitor.
The analog output stage is based on the Nova proprietary circuit that uses JFET as active devices and is characterized by a single gain stage and the total absence of any feedback. The individual active components are selected individually.
For the digital and the control circuits and for the signal handling circuits, the power supply, starting from two toroidal transformers, is completely independent. A particular system has been adopted for filtering the power supply of the conversion and the analog units; a system that significantly reduces reciprocal noise between the various circuits. Consequently, the sound obtained is harmonically richer and the sound fade-out more natural.
The passive components used include high quality parts such as electrolytic capacitors, with extremely low internal impedance, polypropylene capacitors and low-noise metal film resistors. Each individual component has been chosen according to the real sound quality, determined through numerous listening tests.

NOVA NCD 2

The NCD2 player uses Philips CD Pro 2 transport, one of the best CD modules currently available, inserted in a particular, semi-rigid system composed of a steel and wood mass suspended on anti-vibration mounting pads.
The conversion unit develops around the top-of-the-line Analog Devices converter, the AD1955, in dual mono configuration, and an upsampling circuit that raises the resolution of digital data, based on an Analog Devices AD1896 integrated circuit. The entire digital signal conversion system is mounted on an independent printed circuit board that can be easily removed and replaced in case of technological updates, without having to change the entire player.
Thanks to the high sampling frequency, it was possible to use a first order analog filter made up of a metal film resistor and an exceptionally high quality silver mica capacitor.
The analog output stage is a discrete components design. Even for the critical current to voltage conversion it has been used a single stage discrete topology. The individual active components are selected individually.
For the digital and the control circuits and for the signal handling circuits, the power supply, starting from two toroidal transformers, is completely independent.

NOVA NIA 1

The NIA1 integrated amplifier has been developed around an innovative amplification topology used, on an exclusive basis, by Nova in its products. The particularity of this circuit is the total absence of any form of negative feedback. In fact, a unique solution is used that can compensate the intrinsic non-linearity of active devices rather than correct it with the negative feedback. The negative feedback, used in nearly all products on the market, often results in an unnatural or "transistorized" sound; moreover, it also can determine a compression or harmonic impoverishment of in the music being played.

In order to reduce manipulation of the musical signal to the barest minimum, the circuit used consists of just two stages of amplification: the first feedback-free stage serves for voltage amplification; the second, made up of a buffer of six Mosfets, provides current amplification.
To control the volume, an Analog Devices digital potentiometer is used that has 256 steps “compressed” into 100 levels (0-99) so as to obtain a pseudo-logarithmic regulation. This component is made up of an array of precision resistors switched by mosfets. Therefore, as opposed to other similar products, there are no active devices (operational amplifiers) which could cause a decline in musical performance.
Given the absence of any feedback, the single active devices are selected individually.The passive components used include high quality parts such as electrolytic capacitors, with extremely low internal impedance, polypropylene capacitors and low-noise metal film resistors. Each individual component has been chosen according to the real sound quality, determined through numerous listening tests.
