Audio Analogue Maestro Integrated Amplifier
The Maestro Anniversary was born out of the development of the special Puccini Anniversary. The basic scheme is very similar, but with one important difference: the amplification chain is fully balanced from the input to the power stage which becomes unbalanced to connect to the speakers. This took to a doubling of amplifier stages and attenuation. Also in the Maestro Anniversary all stages are without global feedback. The feedback is not even used on preamp stage (as in Puccini). The output power was increased to 150W at 8Ω with the consequent adjustment of all the driver and power stages that now use four pairs of transistors per channel. The basic configuration remains inverted cascode that is comparable to a single gain stage followed by the output buffer. The stability of the working point is maintained through a DC Servo that begins to work only at frequencies below a few tenths of Hertz (then totally out of the audio band). Thanks to this ingenious circuitry, along with the selection of components of the highest level (military standard resistors, polypropylene audiograde capacitors custom made for Audio Analogue, internal wiring with 7N OCC copper and pure copper output connectors) creates an integrated amplifier which pushes the boundaries of high power solid state to unparalleled heights.
The new Maestro Anniversary's remarkable power doubles with decreasing impedance and its extraordinary drive is accompanied by a unique musicality and refinement unheard of for so “muscular” amps. It's of course not easy to express in words this special balance of ease and naturalness and the incredibly dynamic control on offer, and therefore we invite you to listen to it as proof that the Maestro is something very special.
