The Master Stroke amplifiers reveal the synthesis of decades of research applied all'audiofilia, with passion and rigor GTTrading the group has realized the precious occurred collaborations with leading exponents of Italian loyalty and Steg has yet to be signed once the finish line amplification for mobile use. With the development of the Master Stroke we defined new standards: these electronic demonstrate unprecedented qualities in terms of beauty of sound, power and solidity. No compromise! Every construction detail corresponds to the thorough verification of complex projects, honed to perfection. Master Stroke revolutionizes any knowledge gained on high fidelity car and the limits that were believed immutable move beyond measure later, moving over to what, until now, it was believed impossible ...

Six extraordinary electronic, designed to meet the most demanding audiophiles and drive systems SPL competition. innovative amplifiers, capable of very high currents, insensitive to the lower load impedances, up to 2ohm bridged mono. elegant and sophisticated design, all aluminum chassis with integrated tunnels that the active cooling system. Built with quality materials, selected to enhance the most sophisticated installations and ensure the highest level of reliability. Extremely versatile, incorporating a wide range of functions associated with each other and able to configure complex audio systems, without the aid of external devices. Stabilized from 11 Volt, Watt many well-sounding, always. Support SERIALPOWER configuration: the stereo models are connected with each other to add the power of two units as it were a single amplifier. Incorporate a microprocessor that manages the complex system of protection and that, through the STEGLINK door, can communicate with the PC. Kcompetition is the new way to amplify STEG, destined once again to move forward any reference.

August 2016 the GTTrading is proud to introduce the new ST line amplifiers. Audiophile Transistor output stage, dual differential input to eliminate any noise generated by the car radio, make that the new ST line can satisfy the most demanding audiophiles. innovative amplifiers, capable of very high currents. elegant and sophisticated design, all aluminum chassis. Built with quality materials, selected to enhance the most sophisticated installations and ensure the highest level of reliability. Extremely versatile, incorporating a wide range of functions associated with each other and able to configure complex audio systems, without the aid of external devices. Possibility of ignition with autosense, (arrival of the audio signal is switched on and goes out as soon goes away the audio signal), the input possibilities in High Level. ST series is the new way to amplify STEG, destined once again to move forward any reference, in these three models is enclosed 30 years of experience in the design and production of car amplifiers.

August 2016 the GTTrading proudly presents the new DST amplifier line. Three extraordinary electronic, designed to meet the most demanding installations. innovative amplifiers, double differential input to completely stop the ground loop, so that in any condition of use are eliminated all the disturbances generated by the control units of cars. elegant and sophisticated design, all aluminum chassis. Built with quality materials, selected to enhance the most sophisticated installations and ensure the highest level of reliability. Extremely versatile, incorporating a wide range of functions associated with each other and able to configure complex audio systems, without the aid of external devices. DST series is the new way to amplify STEG, destined once again to move forward any reference, in these three models is enclosed 30 years of experience in the design and manufacture of amplifiers for cars. The DST line is born to the needs of our distributors / installers to have smaller size for "invisible systems". Small size, superior returns to 80%, possibility of ignition with autosense, (arrival of the audio signal is switched on and off as soon as the audio signal goes away) Input possibilities in High Level, make that the new line DST can have applications on all new cars including electric. To date it was unthinkable to realize the class D amplifiers with timbral performance superior to the AB class, but with this new line we succeeded in full.

March 2019 GTTrading is proud to present the new line of DSTII amplifiers. Three extraordinary electronics, designed to satisfy the most demanding installations. Innovative amplifiers, double differential input to completely interrupt the ground loop, so that in any condition of use all the disturbances generated by the car's control units are eliminated. Elegant and sophisticated design, completely aluminum chassis of very small dimensions. Built with fine materials, selected to enhance the most refined installations and guarantee the highest level of reliability. Extremely versatile, they incorporate a wide range of functions that can be associated with each other and can configure complex audio systems without the use of external devices. DSTII series is the new way to amplify STEG, once again designed to move forward every reference, in these three models contains 30 years of experience in the design and manufacture of amplifiers for cars. The DSTII line was created for the needs of our distributors / installers to have reduced dimensions for "invisible" systems. Small size, efficiency over 80%, possibility of turning on with autosense, (when the audio signal arrives turns on and off as soon as the audio signal goes away) High level input possibilities, make the new line DSTII may have applications on all new cars including electric cars. To date it was unthinkable to be able to create class D amplifiers with higher tonal performance than the AB class, but with this new line we succeeded in full.

March 2018 GTTrading is proud to present the new line of QM amplifiers. Two extraordinary electronics, designed to satisfy the most demanding installations. Innovative amplifiers, dual input differential to completely stop the ground loop, so that in any condition of use are eliminated all the noise generated by the control units of the car. Elegant and sophisticated design, all-aluminum chassis. Built with quality materials, selected to enhance the most refined installations and ensure the highest level of reliability. Extremely versatile, they incorporate a wide range of functions that can be linked together and can configure complex audio systems without the need for external devices. QM series is the new way of amplifying STEG, destined once again to move forward every reference, in these three models it contains 30 years of experience in the design and realization of amplifiers for Cars. The QM line was created for the needs of our distributors / installers to have reduced dimensions for "invisible" systems. Reduced dimensions, yields over 80%, possibility of ignition with autosense, (when the audio signal arrives it turns on and off as soon as the audio signal goes off) possibility of entry in High Level, make that the new line QM may have applications on all new cars.
