Which Is Better？ Power Amplifier Toroidal Transformer Or EI Type Transformer?

Which is better？ power amplifier toroidal transformer or EI type transformer?

The function of the power amplifier is to amplify the weak signal from the pre amplifier or sound source, and promote the sound of the sound box. And as the core electronic components of the power amplifier

Which is better? power amplifier toroidal transformer or EI type transformer?

The first to compare the advantages and disadvantages of toroidal transformer and EI type respectively,
Toroidal transformer short magnetic circuit, high efficiency, copper loss and iron loss are less than EI type transformer, small volume and light weight, convenient installation and use, for the shortcomings of anti DC saturation poor performance;
Advantages of EI processing is easy to make the winding is convenient, anti saturation good performance. The defects are large magnetic flux leakage, large volume weight under the same power, and relatively low conversion efficiency.
In general, two kinds of transformers can be used in power amplifier, each has advantages and disadvantages. Comparatively speaking, many audio enthusiasts and manufacturers prefer to use toroidal transformers as audio transformers.
So the advantage of  toroidal transformer is obvious.
