AUDIO ANALOGUE Maestro Anniversary: Integrated Amplifier, 2 x 150 W at 8 Ω
Maestro Anniversary: The Evolution of a Sonic Legacy
The Maestro Anniversary amplifier was born in AIRTECH laboratories, building on the experience gained from developing the Puccini Anniversary. While both share a basic design framework, the Maestro introduces significant enhancements, particularly in its fully balanced amplification design from input to power stage, where it unbalances at the speaker connection. This architecture required duplicating the amplification and attenuation stages, along with the absence of global feedback in all stages, including the preamplification stage, setting it apart from the Puccini.
Increased Power and Technical Refinement
The Maestro Anniversary increases output power to 150 W at 8 Ω, with specific adjustments in the power and driver stages, utilizing four pairs of transistors per channel. It maintains an inverted cascode configuration, equivalent to a single gain stage followed by an output buffer. The stability of the operating point is ensured by a DC servo that operates only at extremely low frequencies, below the audible range.
High-Quality Component Selection
The advanced circuitry of the Maestro Anniversary is paired with top-quality components, including military-grade resistors, polypropylene capacitors custom-designed for AIRTECH, internal wiring made of 7N OCC copper, and pure copper output connectors. These elements contribute to exceptional sonic performance, positioning the Maestro Anniversary as a worthy successor to the iconic Maestro amplifier.
Balanced Musicality and Power
The Maestro Anniversary combines impressive power, doubling as impedance decreases, with refined and unique musicality. Its design excels not only in technical capability but also in delivering a sonic experience rarely found in amplifiers of this power range.
A Tribute to Tradition
Celebrating 20 years of Audio Analogue and 15 years since the introduction of the original Maestro, the Maestro Anniversary honors its legacy with a design that unites power, musicality, and refinement in a single device. Beyond words, this amplifier is designed to be heard, confirming its excellence with every reproduced note.
Music, Maestro!
