Confused! We speak about Hi-Fi but are happy with adding distortion, pleasant sounding or not?

Magnetization follows the “hysteresis” curve which creates a non linear response in the transformer.

This creates second order harmonic distortion which sounds “warmer.”

Voltage stabilizer is a one of the most crucial part to regulate the electric fluctuation across to protect all electrical equipment but not every voltage stabilizer comes with isolation transformer. An isolation transformer isolates the circuit from main ac supply and serves the product with longer life.

the downside of the transformer is that it changes the sound more or less depending on transformer design and many other details. Change of sound can sometimes used as intended effect.

why not? Is there a downside to adding Transformers?

maybe, some manufacturers give you the option to bypass the transformer because it can change the sound so…. it may or may not be a good idea could depend on the transformer itself. It’s one of those things you won’t know until you try it. There was a Joe Meek preamp that had a switchable transnsformer and to be honest I preferred the transformer switched out.
