T,

I would like to ask you a question. Understanding that amorphous core material comes in many types still, if to generalize it them might I propose an observation that beside all amorphous sonic and technical advantage (presumably they exist) the amorphous core transformers have some sonic idiosyncrasies.

It hard to explain was it is and practically for me who is not familiar with relationship between the core materials and sound of the materials. Still, I know how it should sound and my observations that the amorphous core in some way very-very-very-very-very-very slightly depersonalize the HF. I would put in this way: if I build a 10-channel amp then I would defiantly use the amorphous core for MF channel and for mid FH channel. However, for the higher HF channel I would go for a super low inductance none-amorphous. What I feel that amorphous core make sound “strong” and “muscular” that is not what I want at the highest frequencies. Do not confuse it with the crappy silver sound or anything else: amorphous is problem free tonally. I ‘m talking about rather the “overconfident virility” at the highest frequencies then about some kind of “audio” problems.

Perhaps the amorphous core magnetic that works at the very HF should be load differently? For instance the transformer that work at the very HF should loaded much harder than it typically would? Perhaps it would bring out some “overly-richer harmonic content” and might slightly “soften up” the amorphous transformers?

T, would you elaborate on it if you feel that it has any merit?
