SPETTRO Preamplifier "Dual Drive System" in Class “A” + Phono (MM): £13250

The SPETTRO Preamplifier represents the pinnacle of tube pre-amplification, with no integrated circuits used in its design. Every aspect of this preamp has been meticulously engineered for optimal performance. At its core, the SPETTRO features a Dual Drive System comprising two parallel preamplifiers per channel. This unique configuration halves the output impedance, resulting in an audio signal with astonishing speed, dynamics, and transparency.

This technology offers superior signal management, ensuring the connected power amplifiers can fully express their potential. Seven carefully selected double triodes power the signal path, and all components are custom-made to the highest standards.

The power transformer, designed and manufactured in MastersounD's laboratories, is another key element of the SPETTRO’s performance. The latest edition includes significant upgrades to the circuit, featuring a new PCB design and an advanced analogue signal filtering system that enhances signal purity and transparency.

The SPETTRO’s low output impedance makes it compatible with any power amplifier and allows for a variety of system configurations. However, paired with our mono or integrated amplifiers using the "Direct" input, it delivers its full potential, offering a truly unparalleled listening experience. This is a new era in preamplifier technology, setting a revolutionary standard for what is possible.
