Sven,

Your correct in USA we use mF or uF interchangeably.    Besides what Ole 
said one has to make sure of low ESR and some caps react differently 
depending on if a signal is symmetric or asymmetric, one can see this 
with a curve tracer.  I think the attribute is called absorption but I 
forget.

For sound we prefer oil or poly or teflon film over mylar film and 
ceramics or tants.   Also some manufacturers use steel for the leads of 
caps and resistors which has a magnetic property we don't like to hear. 
Foil resistors with copper leads sound best but are prohibitive with cost.

Teflon caps are really nice sounding but although and amazing insulator 
is a poor carrier so it takes some larger sizes in teflon than polyfilm 
materials but they can usually handle a higher voltage.  I don't know if 
any of this is relevant to your work but have a gut feeling sound has 
similar properties to some of the aether magic we chase.
