Classification of amplifiers and distinction between tubes and transistors

Although a power amplifier can not determine the sound quality from the outside, if you can observe the size of the power transformer and filter capacitor, you have already know the performance or quality of the machine first. Class A work certainly requires a huge power supply, even if the class AB machine is as large as possible. Many high-quality power amplifiers today use toroidal transformers, which are more efficient than square transformers and have less magnetic leakage. The filter capacitor is equal to the pond. The more water storage, the better the water supply, and the power supply of the power amplifier is sufficient and stable to ensure that the output of the output transistor is still inexhaustible.

Many UK-made combined amplifiers, although not very powerful, have a very rich power supply that can achieve excellent sound with a simple signal path. In addition to the volume, balance, source selection and power port, the control of some products is completely canceled, so that the signal channel is shortened as much as possible. In pursuit of pure sound, do not hesitate to sacrifice control functions.

Tube amps are commonly known as amps, which are known for their sinful sounds; transistor amps, commonly known as stone machines, are known for their masculine.

The advantages of the transistor machine are high current, wide frequency band, low frequency control force, analytical power, layering and brightness when dealing with large scenes are superior to tube amps, but the high pitch of the tube machine is smoother and has a sufficient air feel. A lot of people like the sound dyeing, although the sound details and levels are less, but the soft and slightly fuzzy sound is beautiful.
