AVM Ovation MA 8.3 (pora)
Power and precision without compromises
The Ovation MA 8.3 mono power amplifiers deliver an impressive 1,100 W per channel, effortlessly driving even the most demanding speakers. Featuring Ovation 83 T tube technology and 24 MOS-FETs per channel, they guarantee a sound reproduction that is both powerful and delicately nuanced. Two 1,000-VA toroidal transformers and capacitor banks with 80,000 µF capacity ensure virtually unlimited power reserves. Ultra-short signal paths and symmetrical input stages maximize precision and sonic fidelity.
Elegance meets high-end technology
The MA 8.3 impress with their elegant design and robust construction. The aluminum housing, available in silver or black, is optionally offered with a chrome front. A transparent glass top provides a view of the flawless internal technology. With a weight of 85 kg per pair, these amplifiers embody stability and durability.
Handcrafted at the AVM facility in Malsch, the MA 8.3 undergo rigorous quality checks and an extensive multi-day burn-in process to ensure maximum reliability and exceptional sound quality. An indispensable element for any audiophile setup.
