Sketched out by an Italian designer named Andrea Pivetta, the “Opera Only” amplifier is the largest and most expensive in the world, flaunting a height of 8.2 feet as well as a price tag of $2.2 million. This massive technological masterpiece looks absolutely amazing, which is why some might be inclined to see it as a functional work of art instead of a “simple” sound amplifier.
Needless to say, there’s nothing simple about this thing since it includes 2,112 high current bipolar transistors cooled off by six fans, as well as six-30 kW triple-insulated toroidal transformers. All in all, the “Opera Only” is able to ensure 160,000 watts of power that are channeled via two 80kW channels or in six-channel mode.
Weighing in at 3,307 lb, the amplifier measures 4.1 x 6.2 x 4.1 feet in idle mode and 6 x 8.2 x 6 feet when it opens. The “Opera Only” amplifier is made using steel and aircraft-grade aluminum, while the building process itself requires 6 months to complete.
