Which of the following types of ring, EI, R, and C power transformers is the best?

 They all have their own advantages and disadvantages, and no one has the best, so strictly speaking, which kind of transformer can do well. Structurally speaking, the ring type can achieve the least magnetic leakage, but the EI type can make the medium frequency density better. In terms of magnetic saturation alone, the EI type is stronger than the ring type, but in terms of efficiency, the ring type is superior to the E type.  Nevertheless, the key to the problem is whether you can make the best of their strengths by taking advantage of their strengths and avoiding weaknesses. This is the most fundamental thing to do with transformers.
 In the current imported amplifiers, the application of toroidal transformers is still the mainstream, which basically illustrates a problem. Enthusiasts should be objective and fair in evaluating the transformer. You can't take a bad reference and say it is not good. Some people say that a toroidal transformer is easy to magnetically saturated, so why not try to make it difficult to magnetically saturate it? This can be done by technical means. If you don't have to work hard or simply save money, then it is easy to magnetically saturated. In the same way, as long as you carefully make, the efficiency of the EI-type transformer can also be very high. The quality of the transformer has a great influence on the sound, because the transmission energy of the transformer is closely related to the iron core and the coil, and the transmission rate plays a decisive role in the influence of the sound. Like the EI type transformer, people usually think that its intermediate frequency is thicker and the high frequency is more slender. Why? Because its transmission speed is relatively slow. And what about the ring? The low frequency is fierce, and the middle and high frequency are slightly weaker. Why? Because it transmits faster, but if you change the structure through an effective structure, you can do both the ring and the EI, so the key is to see how you do it.
 But at least for sure, the R-type transformer is not too easy to do. It can also be used to make a small current preamplifier and CD player power supply. If it is used as a power supply for the post amplifier, there are serious defects. Because the structure of the R-type transformer itself is not easy to change, the ring type and the EI type are relatively easy to change the structure to achieve the humming purpose. Power amplifier power supply made with R-type transformer, usually sounds very tight and lacks aura, low Frequencies often appear to be harder without bounce.
