Tube Preamplifier "Dual Drive System" in Class "A"
Derived from the "PHL5", the "Spettro" expresses the maximum in tube preamplification. Inside, no integrated circuit is used, everything has been designed to state-of-the-art standards. Inside the "Spettro" there are a pair of parallel preamplifiers per channel (Dual Drive System) with the intent of halving the output impedance and thus obtaining an audio signal of truly surprising speed and dynamics. The final amplifiers driven by this preamplifier can truly express all their potential. Between the phono stage and the line stage, there are 7 dual triodes and all components are highly selected and custom-made. The power transformer was designed and manufactured in our laboratories. The latest edition encompasses all the improvements made to the circuit over the years, with a new PCB board and an analog signal filtering system that allows for greater signal cleanliness and transparency.
