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.

@erik_squires I’m completely rebuilding my XOs. I have CSAs on the coax board and am comparing with and without Multicap RTX bypasses (~1%). I might also try a CMR bypass. Please characterize for me the SQ of Jupiter as a bypass. Thanks.
I feel 0.01uF is way to little
I have Multicap RTX bypasses (~1%) on my Clarity CSAs. On well-recorded music this sounds fantastic. Excellent transients with resolution and transparency for days. But poorly recorded music can sound "cool", even thin, most notably on vocals. I’m wondering if a double bypass or different bypass cap might add a bit more flesh or hint of warmth. The Jupiter copper foil at 0.01 uF caught my interest but your post has me second guessing. Two questions:
a) do you think a different bypass or double bypass would result in the sound I seek?
b) if yes, more likely to get a good result with Jupiter double bypass at 0.01 uF or Audyn TC Max at ~1%.
clarity cap was neutral and "ruler flat". I thought that was pretty descriptive. It was clean, but I lost some warmth and color compared to the original solens. The Jupiters brought that back in spades while also adding better imaging.
Nice! Now I'm back to wondering about replacing my RTX bypasses with Jupiter - lol.
