Θεωρείται από τις "δυνατές" (ηχητικά) Class-D υλοποιήσεις ενώ είναι εξαιρετικά δημοφιλής στο US and A. Κι από γκάζι δεν πάει πίσω βέβαια - το αντίθετο.
Μην ψάξετε να βρείτε από που αγοράζουν τα modules...
Έχουν τα δικά τους (αποκλειστικά) κόλπα. :cool_4:
"What makes Spectron DNA different from other digital pulse width modulation switching amplifiers? First, its Class-D modules are unique. They are Spectron’s own design. The Spectron amplifier uses digital logic that corrects for output errors ten times faster than conventional linear circuits. The fast feedback loop preserves accurate time alignment. The Spectron includes the modulator, power section and output filter all in the feedback loop to correct for errors caused by the varying speaker load. This allegedly results in an amplifier that sounds the same with different speakers. The Spectron is stable down to 0.1 ohms and virtually dares you pair it with difficult or complex impedance speakers including ribbon (my Apogees) and electrostatic.
...
In contrast to many lightweight Class-D offerings, the Spectron feels (52 pounds) and looks more like a conventional solid state amplifier with a robust power supply. The Spectron uses a 1.3kVA transformer and one hundred 330uf capacitors to provide massive headroom. It is capable of delivering 120 volts peak and 55 amps peak current for a longer time than most amps. This provides powerful yet musical symphonic crescendos. Want to get Tim "The Toolman" Taylor scary crazy? The Spectron can be operated as a fully balanced monoblock with triple the power and double the headroom.
Listening to the Spectron made me do some serious consideration of how many audio systems are under-powered with the usual fare of 150-250 watts per channel. Despite the power, the amplifier runs very cool and draws only 40 watts at idle.

Conclusion:
While toying with esoteric audio extremes can be a fun fantasy, eventually reality smacks one in the face. Many companies indulge their own egos by designing offerings that require a forklift to move, an auditorium to house, industrial-sized cooling, and a Swiss bank account. Spectron mocks that silliness with a truly amazing package that provides well above average power in an affordable, cool-running, user-friendly amplifier while simultaneously maintaining the highest build quality and establishing a new standard in audio performance. Evolution truly is a wonderful thing. Maybe Class-D will inherit the earth but with Spectron leading the way, there won’t be anything meek about it."
