Tweeter Capacitor Upgrade (Coincident PREs)

Just an update. I did install the clarity cap cmr with a silver duelund bypass. A really nice improvement from the stock solens (Israel actually claims that stock is mundorf)... Much smoother and cleaner. 

I also found some Jupiters and will try them out in a week or two as well.  Apparently there is very little stock at the large values. I had to have them shipped from England, and they only had 4 in stock. Soniccraft said they may never get that value back in stock.

How much a quality of the second order LP filter capacitor does influence on sound quality?

@alexberger

Based on my reading, this can be more important than the coil, even though it is in parallel. Especially if the original is an electrolytic, replacing them with even a modest film cap like a cheap Axon or Solen or Mundorf bipolar is going to be a bigger improvement than changing the coil.

Also, changing these caps is a little dicey, especially if replacing 1980's or earlier speakers, the ESR was pretty high and changes need to be compensated for. If you have relatively recent speakers (2000+) you should be fine.

Hey @cal3713
What value Duelund did you bypass with?
