Spettro

In the circuitry of SPETTRO was not used any type of integrated circuit. Everything has been designed to the State of Art. Spettro has inside a pair of parallel preamplifiers per channel (Dual Drive System), with the main motivation of halving the output impedance. Yes, practically, Spettro has inside four preamplifiers, this gives us greater control of the signal, which will drive the final amplifiers. We are able to come out with an audio signal of a truly astonishing speed and dynamics. The power amplifiers driven by this preamp can really express all their possibilities. Between the phono stage and the  pre stage there are 7 double triodes and all components are highly selected. The power transformer, also is designed and manufactured in our company. Our amplifiers have always had the characteristic of speed and dynamics. The combination of this new pre amp, with the final 300 B Monoblock and Monoblock 845 and the Top Line PF100, only adds to this characteristic of the projects Mastersound. Spettro, of course, can  be combined with any kind of final and always, thanks to its main characteristic, low output impedance, facilitates even more the various possible combinations. It is with pride that we present to the International Show of Munich High End our latest project preamp Made in Italy. Not only a new preamp, but a new concept in preamp technology. A completely new design that revolutionize what has been done so far. Spettro has been designed to get the peak level with the valve power amplifier.
