Two approaches to Amorphous cores
1) The technical approach. For that you need to know and understand what the hysteresis of a transformer material is doing to the signal transfer. This is the higher permeability, lower coercive force, low core loss and low exciting power. Also the shape of the hysteresis curve is more linear, more square shaped. This gives a complex mix of new electrical parameters to amorphous cores, compared to normal steel cores.
2) The listener's approach. Decide for yourself what sound you prefer. With today's modern core materials, amorphous cores are appreciated by "connaisseurs" of tube sound. Before that, there was already the use of this material for some high end moving coils transformers. Theoretically Amorphous material has a fraction higher distortion, but practically the sound is preferred by many. Most comments are like this:
Whatever approach may be right, for sure is, that despite the higher price, there is a fast, very fast growing interest in these products!
