What makes a good audio transformer? With the development of the chip amp, we are hearing some odd reports (ie: bigger and and more robust power supplies not sounding as good as ones less endowed) so... What do we look for in an audio transformer and is what we look for different in a Class A...

The most common core materials for audio transformers are M6 steel (steel with a bit of silicon) and nickel/iron alloys. Cores with high nickel content are more permeable and more expensive, with less hysteresis than steel cores.

Audio transformers should preferably use both high-permeability cores and the largest number of coil turns to create high primary inductance. The most commonly used audio transformer core materials are M6 steel (a steel alloy containing 6% silicon) and 49% nickel or 84% nickel (alloys containing 49% or 84% nickel plus iron and molybdenum).

Fig 11.4.1 Small audio transformer. Audio Frequency (AF) Transformers work at frequencies between about 20Hz to 20kHz and are used in audio amplifier circuits, they were essential in valve (tube) designs for matching the high impedance outputs of theses amplifiers to low impedance loudspeakers, but transistor amplifiers have much less need for output transformers.
Audio Transformer, its Types and Impedance Ratio
https://circuitdigest.com/tutorial/audio-transformer
Audio Transformer creates isolation between the output speakers or audio circuitry with the transformer’s input side amplifier system. The primary and secondary winding turns ratio fixed to 1:1. Due to this, the transformer does not alter the voltage or current level. It does only create isolation between the Input amplifiers with the output speaker system.

Large transformer often sound better. The larger cores do not saturate nearly as easily during the peak current demands. Jocko and I have measured this and noticed a subjective correlation between transformer size and sonics. Even for low current circuits like preamps, large transformers tend to sound better.

Transformers are big, bulky, expensive, and difficult to make in good quality. Audio frequencies cover 20Hz..20kHz, but high-end amplifiers usually have even more bandwidth. This is at least 1000x frequency range. Transformers work well in moderate frequency range, and have issues either at the low or at the high end of the spectrum.

In a class A audio output stage, apart from the impedance match, its helpful to have an output transformer with a combination of factors, such as a high primary inductance to assist the bass response, butt stacking with a thin spacer to avoid core saturation due to the DC current (primary Ampere-turns) and low range winding resistances.
