Finale di potenza

The gold-plated loudspeaker output plugs have been selected for their ability to transmit without alteration all the energy and the micro-details of the electrical signal. The polypropylene film structure link capacitors have been selected for listening in the high-end series of the largest manufacturers. In bridged mono mode, the energy gain is colossal: this operation is suitable for all systems where high power is required. The differential structure diagram makes it possible to carry out this transformation without altering the nuances of the musicality, the gain in ?sound material? makes listening even more realistic.
