The ACCUSTIC ARTS® MONO III – our statement

The brand new ACCUSTIC ARTS® MONO III power amplifier is the latest member of the ACCUSTIC ARTS® family of amplifiers and after the very successful MONO II is the second amplifier from our company which is uncompromisingly designed as a mono power amplifier.
The MONO III is technically related to our legendary AMP III which is very much appreciated all around the world. The inside of the MONO III boasts a combination of 24 MOS-FET transistors and two enormous 1,600 VA toroidal transformers to deliver huge power with up to 1,100 W (4 Ω)  in class A/AB operation. Thus the new MONO III represents the flagship of our range of amplifiers.
Just as with the AMP II – MK 3, the MONO III is also equipped with our new technology for damping factor linearization. Please see PDF document on your left.

Our promise: Handmade in Germany

“Handmade in Germany” is part of the ACCUSTIC ARTS company philosophy and so naturally the MONO II is also exclusively made in our manufacturing facility in Lauffen/Germany. The development, component insertion of PCBs and final assembly takes place in Germany and all housing parts and many individual components are sourced from long-term suppliers based in the south of Germany. Our specially trained and experienced technicians build this high-end audiophile amplifier from a large number of individual components.
