Warn Sound Capacitor

thank you for your answer.
between esa, px and csa which is the warmest?

about mundorf they are overexctited in the highs (IMHO)

Haven't heard ESA.  PX is definitely warmer than CSA.  I use both in different speakers and the CSAs are very neutral.  

HI,
Humblehomemadehifi has a nice shootout of caps. I like Clarity Caps they do not cost a fortune and sound right. I have used MR and ESA in my preamp, both different. Warmer and rounder of the two is ESA but you can try the better CSA which has more air than ESA.

Clarity CS line is very warm.  So is the Mundorf MKP.

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
