The inside of a Rockford Fosgate T500-1bdCP showing the transformer (the coil of red and green wires) and output transistors (black rectangles glued to the heatsink with white thermal paste). AB amplifiers are inherently distorting (the crossover problem), just like many tube amplifiers (grid voltage to plate current characteristic follows a square law ). However, Class AB Amplifiers are famous for better sound. Asghar, I'm not exactly sure, but I think the Class F element adds a dual transistor push-pull circuit to the Class D amp stage. A Class A amplifier's output transistors run with "constant bias," meaning they always run at full power whether there's an input signal or not. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee. I recommend you to my friends.

Audio Exchange is a retail, brick & mortar Audio/Video store that has been serving the Richmond, VA area since 1978. The buzz results from crossover distortion that produces a dead spot of lower gain at the crossover point. High quality audio for the massed disappeared because the public preferred distorted sound. In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. A class-D amplifier or switching amplifier is an electronic amplifier in which the amplifying devices operate as electronic switches, and not as linear gain devices as in other amplifiers. Please consider writing a book on electronics 101/for dummies. The difference is night and day! I just bought a set of Focal speakers to match against my Alpine 6×9 3-ways, and was SO disappointed in the bass (penetration and dispersion) AND treble (symbols especially) until I switched to an old Crunch A/B amp - same RMS wattage output (never thought much of Crunch before, but "loved" Alpine).
