Like in Dante Alighieri's "La Divina Commedia" I feel me like I'm entering a "selva oscura" - i.e. the darkest forest ever!


After last Nov. 2009 when I put in place the mighty Thomas Mayer's preamp(s), my Gotorama system is still hungry - like myself;-) - of further refinement, as I see them to be almost virtually endless... from subtlety to new subtleties, I feel I reached something... but simply want to go further and further again.



Jorge from Mexico City kindly hinted to me about Current Charged Caps in place in passive crossovers and he's also using horns and high efficiency drivers ... so, I just began browsing the Web for more detailed pros & cons on the matter.



Voltages? PSU? Batteries? What amperage and voltage is involved? Paper in Oil, Current Charged or exotic caps from Northern Europe (Germany and Denmark)? Feel very much like Caronte brought me at the boundaries of Hell... or it's Heaven?

    This reminds me

    I am my own heaven and hell! ~J.C.F. von Schille

    and that.....

    There are two things to aim at in life: first, to get what you want; and after that, to enjoy it. Only the wisest of mankind achieve the second. ~Logan Pearsall Smith, Afterthoughts, 1931

    We are tied to both...but hey it is such fun!

    Hi Peter... still investigating... something exists in Lansing Heritage, but I'm walking in (for me)brand-new territories...
    Will revert soon.
    Cheers,
    S.

    You could read this :

    But aren't all caps charging passive components, with effect that varies when used in AC or DC?

    ho-hum,

    that is the electrickity 101 stuff on caps. I thought the ‘Current Charged Caps’ would be something hot, like biassing caps with batteries.

    thanks,

    ... indeed, Peter...

    I'll contact Jorge from Mexico City who's already using this VERY method in his system.

    Stay tuned...
