reveals the black side of the Power


Undoubtedly a new and fantastic combination of sophisticated technology and artistic avant-garde that has never before been applied in the field of High-End Audio devices. Having at disposal and operating this device, it may be an absolutely thrilling experience: it “comes to life“ opens and his shape that changes completely, foresees the power of its performance. It is not only a technical and functional tool, but a work of art that fascinates and involves in its articulation. We believe that it is not possible a simply description of the object: the fascination of its operation is absolutely indescribable and it can be only experienced.

The external structure is made of aircraft aluminum and the openings or connections are not visible from the outside, and if he or it is switched on, we feel the dark side of the its Power, which you just have to experience personally. When turned off, it is an impressive black 12-sides prism (WHD) 1.25 x 1 x 1.25 m (49.2" x 39.4" x 49.2"), 800 kg (1.764 lb), but its structure changes completely once the device is turned on 1.85 x 1.3 x 1.85 m (72.8" x 51.2" x 72.8"). It is divided into four distinct sections to reveal all the electronics at a glance. Suddenly you have the impression that you are looking into the technology space!

This unquestionably gorgeous state of the Art Amp features: power input 230/400V 50/60 Hz 120 Amp(400V), 3 x 16 kW triple-insulated toroidal transformers, 8 ceramic diodes 1600V/400A, 108 Kendeil aluminium electrolytic capacitors 6800uf 160 Volt, 528 high current bipolar transistors, 12 analog (RCA/XLR) inputs and six digital, 12 output channels, and 96 speakON connections. It's capable of producing an awe-inspiring 24.000 watt rms at 8 ohm class A, distortion: THD+N 0.002%, speaker impedance: down to 0.1 ohm, frequency range: 20 – 20.000 Hz (the specs show output configurations of 6 x 4.000W rms or 12 x 2.000W rms). The sound really must be experienced in person. However, it is quite easy to imagine how the "DarkBlock" sounds before being able to audition it: one look at the amplifier is all it takes "Purity and Power" exactly as you would imagine. The "DarkBlock" is monstrous in all respects: it’s massively sized, heroically engineered, but it flies with powerful yet delicate wings – it conquers any, and I mean any, speaker load, and with transducers of equivalent stature it can convey profound sonic beauty.
