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.
