     This Weekend I had the chance to audition 2 more brands of polystyrene
capacitors in my test setup: Seacor & RelCap.

I received the Seacor's as samples from the company.
These are from their more expensive line and are yellow tubular style.
Sonically these have a slightly dark & warm coloration, not bad.
These appear to be more resolving then most of the other brands I've tried.
Their colorations are mostly inoffensive...  These would probably sound 
right at home in a 2yr old conrad-johnson preamp.  
I'll give them third place.
(minimum order appears to be 1000 & cost ~$2each for 1%@630V)

The RelCaps were part of someone's update for a Theta A preamp, which my 
friend bought with a used circuit board through AudioMart.
One of these was an axial black cube style, the other tubular yellow style.
These are Excellent capacitors.  They have very good detail and pass through
dynamics very well.  They don't seem to resolve the upper octaves as well as
my favored Siemens.  I can imagine where they could be preferrable though.
I'll give them second place.
Several mail-order places list these in their ads,  I'll have to check on 
what values are available... 

My favorite capacitor for small values is still the SIEMENS B33062 series.
These are little clear tubular capacitors with a red endcap on one side and
a white endcap on the other.  There are no markings denoting them as SIEMENS.
If you see these guys anywhere, send me a note...
