[. . . ] audio analogue soundpleasure A wide set of careful solutions inside the units and the use of selected components and cables make this an extraordinary line. Four years of continuous research based on listening tests performed under Claudio Bertini's supervision (Claudio is one of the Audio Analogue co-founders) make the remarkable excellence of these products now available to the wider public. Audio Analogue has decided to take advantage of the Special Edition Line to introduce the most innovative and experimental audio technology. Technology which, because of its complexity and originality, has never been used in production before. [. . . ] Altre innovazioni riguardano l'uscita Mono/ Pre Out configurabile, la aggiunta di nuove interessanti funzionalità e lo stadio di pre Phono. Class A Integrated Amplifier SE and Class A Power Amplifier SE The Class A Integrated Amplifier SE and the Class A Power Amplifier SE come after a four year period of diligent research that Audio Analogue has been developing on the standard Class A amplifiers. The research, directed towards a perfect tuning of the units, has concerned both the selection of the passive components (with special attention paid to the capacitors) and several inner wiring strategies. The implemented changes in such areas have permitted the units to reach a higher level of audio performance. Maestro Duecento Integrated Amplifier SE and Maestro Duecento Power Amplifier SE La ricerca, finalizzata ad accordare perfettamente le varie parti degli apparecchi, ha riguardato sia la selezione dei componenti passivi (con particolare attenzione ai condensatori) che delle varie configurazioni di cablaggio portando ancora più in alto le performance di riproduzione audio. Il Class A Integrated Amplifier SE e il Class A Power Amplifier SE nascono dalle ricerche che Audio Analogue ha portato avanti negli ultimi 4 anni sugli standard degli amplificatori Class A. La ricerca, finalizzata ad accordare perfettamente le varie parti delgli apparecchi, ha riguardato sia la selezione dei componenti passivi (con particolare attenzione ai condensatori) che delle varie configurazioni di cablaggio portando ancora più in alto le performance di riproduzione audio. The research, directed towards a perfect tuning of the units, has concerned both the selection of the passive components (with special attention paid to the capacitors) and several inner wiring strategies. The implemented changes in such areas have permitted the unit to reach a higher level of audio performance. Maestro Line Preamplifier SE The Maestro Line Preamplifier SE has been developed based on the Maestro Line Preamplifier, completely renewing the power supply stage and improving the preamp section after highly accurate detailed listening tests performed on the passive components. The implemented technologies and the manic attention in choosing each passive component has elevated the sound output to absolute reference quality and has made the sound of the Maestro Line Preamplifier SE a benchmark in the category of preamplifiers of the very highest level. VR Power Supply (voltage reference): The power supply we have designed develops a philosophy different from that generally followed in the audio field. In fact, the power supply is normally obtained from a secondary stage of the transformer whose voltage is rectified and then stabilized and filtered as much as possible in order to reduce the ripple. In the Maestro Line Preamplifier SE a "traditional" power supply, such as the one previously described, has been implemented to have a very clean voltage (as much as 3 different stabilization stages have been used for each supply!) but the voltage is not used to supply the preamplifier section!Instead, the voltage, which is already very clean, just supplies the circuit where the proper voltage for the preamplifier circuits is generated. The voltage to supply the preamplifier section is derived from an extremely clean and stable (both thermically and temporally) voltage reference. Such voltage is hence treated to reach the level required for the preamplifier section. All the chain has been designed using extremely low noise strategies. The board for example is a 4 layer one (to have a generalized bypassing of every signal) as apposed to the standard 2 layer boards commonly used in the audio field. . . Pre section: the preamplifier section has been revisited changing the passive components after a series of highly accurate listening tests. In the course of such tests many different kinds of passive components have been checked in several different positions to obtain the best sound coherence. Moreover, in some parts of the board the lay out has been changed to emphasize some particular characteristics. Il Maestro Line Preamplifier SE è stato sviluppato sulla base del Maestro Line Preamplifier rinnovandone completamente lo stadio di alimentazione e migliorando la parte di preamplificazione mediante accuratissimi test sui componenti passivi. Le tecnologie utilizzate e la attenzione maniacale nella scelta di ciascun componente hanno portato la resa sonora a livelli di assoluto riferimento nella categoria dei preamplificatori di massima qualità. Alimentazione VR (voltage reference): La alimentazione sfrutta una filosofia diversa da quella generalmente seguita nella realizzazione di alimentazioni per applicazioni audio. The separation between the gain in tension and of the gain in current permits to realize class A tension amplifiers made with low power components, so to obtain a frequency response up to about 500kHz. Such frequency extention gives the possibility to mantain the phase errors to a very low level.
