The new Master Stroke amplifiers in D class, reveal the synthesis of ten-year research applied to audiophilia, with passion and rigor the GTTrading 
group has concretized the precious collaborations that took place with the major exponents of Italian high fidelity and Steg has once again signed the 
milestone of amplification for mobile use. With the development of the Master Strokes we have defined the new terms of comparison: these electronic 
show unprecedented qualities in terms of beauty of Sound, Power and Solidity. No compromise! Every constructive detail corresponds to the scrupulous 
verification of complex projects, refined to perfection. Master Stroke revolutionizes every notion acquired on high fidelity in cars and the limits that were 
believed to be immutable move disproportionately forward, moving beyond what, until today, was believed impossible ...
