And the very same is with electromagnets. With those so widely used 12V power supplies (Fertin, Feastrex for instance) the sound is always softer than it should be in reality with severally restricted dynamics and transient response. But the people seems to like it...

I agree that each and single electromagnets driver that I head was dull and with restricted transients, something that the unfortunate filedcoil devotee mistakably call “harmonically rich”.

So, you feel that high voltage filedcoil do excite the electromagnets driver somehow? If some then I think if would be worth to try to experiment with high voltage electromagnet.

I will make a few inquires with my cold people and will see if they would propose any rational for it. In any case it might be a good idea to wind a high impedance coil around my S2 driver and to see what it will be able to show off. What voltage you feel is appropriate? Was your selection of 120 was some kind of arbitrarily?  If 120V is better then 12V then why not the 380V for instance? You went to the troubles to use DC battery to drive your 120V coils, why DC battery? How in your view the advantage of DC battery supply relates to the advantage of the high voltage supply? If we accept my above association with a wet Cat as accurate then can your extend that association to the use of DC battery power?
