The ACCUSTIC ARTS® MONO III – our statement

The brand new ACCUSTIC ARTS® MONO III – MK2 power amplifier is the latest member of the ACCUSTIC ARTS® family of amplifiers and has now been further developed and modernized following its successful launch in 2016.

The MONO III – MK2 now has even more power and the ability, drives loudspeaker with an impedance down to 2 Ω.

Sonically, the MONO III – MK2 was further optimized.

It is technically related to our legendary AMP III – MK2 which is very much appreciated all around the world. The inside of the MONO III – MK2 boasts a combination of 20 MOS-FET transistors and one enormous toroidal transformers to deliver huge power with up to 1,350 W (4 Ω) in class A/AB operation. Thus the new MONO III – MK2 represents the flagship of our range of amplifiers. Just as with the AMP II – MK 4, AMP III – MK2, and MONO II – MK2,  the MONO III – MK2 is also equipped with our new technology for damping factor linearization.

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.
