Strumento n° 4
STRUMENTO N°4 stereo power amplifier
The STRUMENTO N°4 is an unrivalled power amplifier where speed, power, driving capability and control ability are elements close to perfection.
A fully balanced circuitry, highly selected components, 48 power devices, a power supply built with extra low impedance, computer grade capacitors (320.000µF only on the main power suppliers), 12 power suppliers, special print boards with an extra high surface copper, copper bars, 3000VA special audio transformers with double shield, ultra fast rectifiers, 200Wrms on 8ohm output power are only few of main elements to give you the best and emotional experience in term of reproduction.
The STRUMENTO N°4 is the perfect device for amplifying musical signal with the best precision, energy and speed (bandwidth more than 1,3MHz) and driving best any loudspeaker system.
It’s the best, the first in the world!
