Tweeter Capacitor Upgrade (Coincident PREs)


Hi all, looking to upgrade the Solen 4.7uF 100V caps that filter the low frequencies out of the Accuton tweeters on my Coincident PREs.  Started by looking at Duelund's, but PartsConnection doesn't even list prices for a lot of the models (or is out of stock) at that value... that motivated me to try and collect some impressions from the group.

Apparently Isreal is using Mundorfs in that position at this point.

As always, thanks for the input.

I am partial to the Jupiter Copper Foil.
To me the Audyn True Copper can be just a little tilted in the upper mids.
The Jupiter Copper Foil paper and wax is my Favorite,although not cheap

Geta2ay from plastics like a Mundorf s ownedtheir Best Silver Gold oil supremes several times . TheJupiter Copper foil 
muc more natural and meaty once you give them 300 hours,
and a Duelund. Silver foil ,oil.01 Bypass cap really opens the top up . Solen is junk,  depending on budget .
go to humblehomemadehifi capacitor test.   A solid A recommendation I usethem myself in my speakers .whileyou are 
at it rebuild the whole Xover austral bloom uses Nothing

fantastic wire . He sells a awg 12 and awg 11 forLoudspeaker cables, and use Copper get rid of the junk brass ,on the terminals 
not natural stall I changed every connection throughout to copper
at lesst a 10% improvement . I used the exsctwiring for my amp-preamp, Loudspeakers also. The whole system .time consuming and maybe $1500 in wire but the results are substantial.
i think isreal uses his top of the line statement cabling inside throughout for his PRE i dont think youd need to upgrade the wiring inside. dont know about the caps.
Here is my thinking:

4.7uF :
Clarity CMR : $54
Jupiter CF: $265

0.1uF:
Jupiter CF: $63

Audyn : $20 (Parts Express)

So somewhere in there I think the OP can find a fine solution. :)
