I have bypassed mundorf silver / oils with .1 sonicap platinum's and yes it does add a little more clarity, Zip or speed, and more solid bass. If cheap enough its worth a shot, but then again I think just using one single better cap if possible might be the way to go, due to add up the cost of an exotic teflon and then the big body type of a mundorf and it might cost as much or in some cases more than just using a cap that will do it pretty close on its own, if its in a small size that is.. For example a 1 uF cap is not too large in value, and a better one vs. bypassing would prrobably be better, but if you got an application of like 2uF or 5 uF I can see the advantage in trying a nice .1 uF to bypass it especially in the cost differences.
