Quote: If you go to the Jupiter web site, select the copper and beeswax product, there is a link to a Lampizator page that has a graph detailing the sonic characteristics of 4 copper foil capacitor brands, V-Cap, Jupiter, Duelund and Jensen.
Of course this chart/graph relates to the caps in Lampzator gear, but it should give some idea of their characteristic sonic signatures. 
I know this post is a bit old, but I figured I would share the link that shows a pictorial comparison of the various caps.  It was very informative.  
http://www.lampizator.eu/Fikus/CAPACITORS.htmlI have been reading all of the SE84UFO25 posts in trying to decide between the copper foil beeswax and the V-Cap when I order my  amp later this year.  The cost to upgrade to the VCap is not a concern.  
With running my Err speakers, and using my new generation Schiit True Multibit DAC, I am trying to discern whether or not a ladder type DAC in general may benefit from a less clinical capacitor like the Jupiter.  
I like tighter bass and love the highs that the VCap offers in comparison to the Jupiter.  But...I am afraid I will miss the representation of the liquid midrange vocals that would favor the Jupiter caps.  Any feedback on my dilemma would be appreciated.  I know I am going
