 Amplifiers can make a huge difference in sound imaging, more expensive or bigger does not always equal better sound.Some people claim that it is better to focus on the speakers since they produce far more distortion than an amplifier. This an excellent example how one can delude himself with facts or numbers. Amplifiers are just as important as the speaker and do need modification. They consist of many components all with unique characteristics and influence on the overall character. Trying to modify an amplifier can become overwhelming if you don't know what you are looking for. First you must set a goal to achieve, for example: 'investigate the source of harsh sounds'. An investigation always starts with schematics, if you don't have them, you must find them or draw them yourself. Never attempt to modify an amplifier if you don't have the schematics. Now you must study the schematics well and decide which components could be a problem. My personal experiences with amplifiers has been that the big differences in sound are always linked to the circuit design. Therefore you'll need to have basic knowledge on amplifiers and their workings. You can find that here. |
