Preamp Output Capacitor: Mundorf Supreme vs. Supreme Silver Oil

Anyone compared the bass response of these two caps?  I bought the Supremes for trial purposes and really loved what they did to my system's imaging (front to back layering) and immediately bought the Silver Gold Oil Supremes.  Unfortunately while they were smoother, more beautiful, and even better at imaging, they had no bass (actually, they lost bass as they broke in).  Anyone know how the Silver Oil's fit into the line?  

I'm using them in a Don Sach's DS2 Preamp ( https://systems.audiogon.com/systems/7983).  

Thanks.

@wig Interesting. Looking forward to the report...

& @atmasphere I also have absolutely no doubt that the vcap's sound amazing in your pre's. Would absolutely love to hear one.

In my pre, with a pretty large cap (2uf) right on the output, going to the vcaps was like turning on a fluoresce light.
Did you give them adequate time to break in? We've got plenty of feedback that says that takes a while.


On paper, Teflon has the best characteristics of any dielectric (although at come frequencies polystyrene can be a little better, but polystyrene is all but extinct). So it should be no surprise that the Teflon also sounds better- lower dielectric constant, equivalent series resistance an so on.

Teflon is a kind of plastic.
Any plastic adds plastic coloration to sound.
Even for wires isolation cotton sounds more organic and natural that Teflon.

Does anybody try to bypass Duelunc Custom Cu capacitors 
with Duelund Bypass Sliver or Duelund bypass Cu-Sn?
How does it work?
Which kind of  Duelund bypass do you prefer?

@atmasphere Yeah, I had them in the pre for a couple months of daily listening... would still love to try the cutf and odams.
