Post Subject: Something more about the “hot magnet” theory.Posted by Romy the Cat on: 2/27/2010

I would like to expense a bit on my post above. If we presume that a warmed up, hot magnet (electromagnet) radiate a magnetic field of different type and those “hot filed” have some kind of positive effect to sound then there is a possibility of model this behavior. Let take for instance an output transformer of SET amplifiers. We can listen it as is. Then we can mount on the transformer core 20-30W power resistor and to drive current across it to heat up the core to 70C for instance. If the assumption that the magnetic field from hot magnet is different was correct then guess the transformer would change sound. I need to be consulted with transformer people how to conduct this experiment in methodologically kosher way…

Also, I would like to note that if the “hot magnet” theory is correct then no one tell about the absolute improvement as it always an improvement in context of the given design. The softening of hardening of sound relates the design of a given driver not to the absolute improvement. It is possible that “hot magnet” might offer some kind of absolute improvement but so far no one person who ever spoke about electromagnets was able to state it without self-incriminating yourself.  The closer to all come probably Oleg Rullit with some of his commentaries that I read on Russian sites. However, his commentaries were not unproblematic and I do not have opinion yet how serious sound-wise all of his “operation” and his sonic experiences.
