Hegel - P30A Stereo Preamplifier The P30A is The Conductor. With poise and control it conveys all the details, the grandeur, the feeling, and the complexity of any piece of music. With precise timing and expert understanding of both the score and the musicians, The Conductor brings forth the music just as it was intended to sound. It handles low key jazz, stadium rock and everything in between. Nothing added, and nothing subtracted, the P30A is the best conductor you will ever meet. First, we use single pair FET transistors that have no higher order harmonic distortion. Within any batch of transistors, there will always be slight measurement variations. This might be within the bounds of what is considered normal deviations, but for sensitive electronics like this, that simply isn't good enough. Therefore, Hegel's founder and chief engineer Bent measures and carefully matches those transistors that have the exact same values. Having perfectly matched transistors is of paramount importance to the performance of the preamplifier, and it makes the P30A sound very smooth and natural, without compromising on the details. Furthermore, the internal layout is designed in a way that makes the signal paths within the preamplifier as short as possible. This reduces the possibility of distortion coming from electrical interference. To further reduce distortion, we also minimize the number of electrical components the signal passes through. In the P30A the music signal only passes through two transistors and an ultra-low noise volume attenuator. The P30A also uses Hegel's patented SoundEngine technology. This actively monitors the music signal for corruptions and corrects for intermodulation distortion using a feed forward design. SoundEngine effectively removes distortion in real time as the signal is amplified.
