Tube phono stages

Tube

— phono correctors, the working circuits of which are made on the basis of lamps.

One of the main advantages of such audio devices is the notorious "warm tube sound", which many music lovers consider the most pleasant and natural. At the same time, this point is rather ambiguous. The fact is that the level of harmonic distortion in tube circuits is several times higher than in transistor circuits, but these distortions are quite specific — they are quite pleasant for human hearing and give the sound a characteristic "atmospheric". But the unequivocal advantage of lamp technology is a good margin for overload. On the other hand, such devices are much more expensive and more complicated than transistor ones, they require warming up after switching on, and the lamps themselves need to be changed periodically (on average, once every few years). As a result, there are relatively few such phono stages nowadays, and they are designed mainly for principled lovers of tube technology.
