Mastersound Spettro
Derived from the “PHL5”, the “Spectro” expresses the maximum in tube preamplification. No type of integrated circuit is used inside, everything has been designed to the state of the art.
Inside the "Spectro" are a pair of parallel preamplifiers per channel (Dual Drive System) designed to halve the output impedance and thus obtain an audio signal of truly astonishing speed and dynamics. The power amplifiers driven by this preamplifier can truly express their full potential. Between the phono stage and the line stage there are 7 double triodes, and all the components are carefully selected and custom-made.
The power transformer was designed and manufactured in our laboratories. The latest edition incorporates all the improvements made to the circuit over the years, with a new PCB and an analog signal filtering system that allows for greater signal clarity and transparency.
