STEG MASTERSTROKE MSK 130.4
STEG Masterstroke MSK 130.4 High End Amplifier. The Masterstroke amplifiers reveal the synthesis of decades of audiophile research. With passion and care, GTTrading realized that the valuable collaborations with leading representatives of Italian loyalty have taken place and Steg has yet to be signed when the target line amplification is available for mobile use . With the development of the Master Stroke we have set new standards: These electronics display unprecedented qualities of sonic beauty, power and solidity. No compromise! Every design detail corresponds to the thorough review of complex projects, refined to perfection. Master Stroke revolutionizes all knowledge of high-fidelity cars, and the limits that were assumed to be immutable, later go beyond what was considered impossible until now ...
