Discreet Power Amplifier Great Sound and low cost

Before proceeding further define discreet: Discreet is not continuous in mathematics relates to the natural numbers and whole and electronics is the central concept of a circuit implemented by the minimum component: transistors, resistors, capacitors, etc., without the use of integrated circuits that meet them within several of these components.

There are several series, the TDA, LM, STK, ... Its sound quality does not meet the required quality in the topic at hand. Because they are designed to get good numbers, do not focus on correcting distortions before they occur and are based on principle and expired in engineering in this field.

You need to do more instead of relying on the good performance feedback. The feedback correcting the distortion, but adds its own and this is the whiting that bites its tail, a club which adds distortion correction. The distortions produced by this technique are difficult to measure and almost never done, aside from the low correlation between the figures (THD, IMD ,...) and hearing as they are raised. Why do they sound good valves with THD between 0.3 and 3%?.
