Description
As in the Maestro Anniversary, all stages of the new Maestro 2.0 are without global feedback. The output power has been increased to 200W over 8Ω with the consequent scaling of all driver and end stages, which now use four pairs of transistors per channel. The basic configuration remains that of the reverse-case code which is comparable to a single gain stage followed by the output buffer.
Compact and elegant shapes, remarkable power that doubles as impedance decreases, extraordinary driving skills combined with a unique musicality and refinement: all of these features make the Maestro 2.0 a practically perfect integrated amplifier.
TECHNICAL DESCRIPTION
The Maestro 2.0 is an integrated amplifier with fully balanced circuitry and zero global feedback. The configuration is completely dual-mono starting from two 670W toroidal transformers. Each stage of the amplifier has a dedicated board for a total of six different boards connected with 7N OCC copper conductors, the same used to produce the high-quality Airtech cables. Special attention has been given to the RR volume control, as this solution allows the user to achieve the reliability and balance of a digital control and to manage four different selectable volume scales. At the same time, signal processing is completely analog thanks to the use of high precision relays and resistors. All the components are meticulously selected and of the highest quality: resistors to military standards, audiograde capacitors and further oversized components specifically chosen to guarantee maximum level performances and reliability.
The Maestro 2.0 is available in silver and satin black finishes and is equipped with a remote control made from solid aluminium.
