Audio Analogue Bellini Anniversary Zero Feedback Line Preamplifier

Audio Analogue Bellini Anniversary Line Preamplifier Delivers Unmatched Sonic Precision and Elegance

The Audio Analogue Bellini Anniversary Line Preamplifier represents a meticulous redesign of the classic Bellini, retaining only the iconic name while introducing advanced circuitry and state-of-the-art features to elevate performance. Developed in the Airtech laboratories, the Bellini Anniversary utilises cutting-edge inductive-capacitive power filtering to minimise AC network noise, providing a pristine power stage that ensures low distortion and superior fidelity. With its sleek, Italian-crafted casing available in silver or black, this preamplifier embodies both timeless aesthetics and sophisticated engineering.

Advanced SeGeSTA Circuit Design for Pure, Balanced Sound

At the heart of the Bellini Anniversary preamplifier lies the SeGeSTA (Single Gain Stage Transconductance Amplifier) stage, offering a completely balanced and zero global feedback architecture. This design reduces signal interference and enhances clarity by eliminating the need for feedback circuits, ensuring that the signal remains pure from input to output. The fully differential circuitry, with dual-mono construction, isolates each channel for exceptional stereo separation and an immersive listening experience. This rigorous design makes the Bellini Anniversary one of the quietest preamplifiers available, ideal for those who demand a deep, uncoloured soundstage.

Noise Reduction Technology for Distortion-Free Playback

The Bellini Anniversary preamplifier includes an inductive power supply specifically engineered to filter noise from the AC network, preserving the integrity of the line stage. The preamp employs oversized military-grade resistors to reduce thermal distortion while relay-based input switching minimises non-linearities, allowing a faithful and accurate signal path. High-grade audiophile capacitors, crafted to Airtech specifications, provide stable and distortion-free playback, resulting in a warm and dynamic sound.

Precision Volume Control and Component Layout for Enhanced Signal Quality

For versatility in speaker matching, the Bellini Anniversary incorporates a digital volume control with four selectable scales, allowing users to tailor the output to their audio environment without the use of operational amplifiers. The carefully organised four-layer circuit prevents cross-talk by physically separating input, output, digital control, and analogue signals, preserving the delicate nuances of the audio signal. This layout and design ensure that the signal remains undisturbed and clean from start to finish, offering audiophiles a rich, detailed playback.

Premium Connectivity and High-Quality Componentry

Equipped with 3 RCA and 2 XLR inputs, and offering both RCA and XLR outputs for flexible connectivity, the Bellini Anniversary easily integrates into any high-end audio system. Gold-plated input and output connectors reduce connection resistance and ensure signal integrity over time. The 7N OCC pure copper internal wiring and included Airtech power cord provide uncompromised signal flow, further enhancing the sonic accuracy and transparency that the Bellini Anniversary is known for.
