Warn Sound Capacitor

ok then try mundorf the white caps, silvergold, a  bit  pricey, but worth it. 
not sure if they are warm/bright, but they are musical/clean

thank you
so for a very open tweeter which cap do you suggest to tame it ?

I don't know if caps will make enough of a difference.  My understand of Clarity caps is they are a bit more higher resolution and uncolored.  The Mundorf caps may be a little colored/veiled in comparison, but that's a hard call.

Probably the best way to tame a tweeter is to start using a lot of pure copper interconnect / speaker cable and ensuring that the terminations are all gold-plated.  Get rid of any silver or silver-plated elements in your transmission line.  This can also include digital cables, such as S/PDIF COAX or HDMI.

to me are mundorf to be enphatized in the highs

If you have a resistor in series, then replace it with Path Audio. Resistors play a big role in tone also.
