Best Capacitors for Crossovers

I am now in the tweaking stage of trying different caps in my crossovers for my DIY homemade 2 way. I presently have and will soon try a 5.6uf 800 vdc +/- 2% Jantzen Audio Silver Z-cap.

I see that Mundorf, V Cap get a lot of accolades, and the Dueland are quite pricey.

Does anyone have a favorite?

I am trying to cross over at about 4500HZ at 6db.

Munforf supreme is a good standard ,med vost nice imdging warm natural presentation for a xover for Tweeter 
Without question I have used many times the Munforf Silver oil.slightly warm and natural.Very good image depth and air . Best value hands down rated very high 
Is the Audyn True Copper caps.  Very large using a lot of Copper foil 
Big and bold nice and rich, open and excellent image depth 
Go to Humble homemade hifi capacitor tests .very accurate Tony has helped me several times while living in Europe.  How much room also is important. 
Inductors always loved the Jantzen  inductors from Denmark.
With resistors Mills are warmer, but for resolution the ohmite gold are very good 
As are thd Munforf white reference . The best and warm may be the Path audio 
Made in Poland .the same company that make the Khozmo volume attenuator. 
Solder very important . WBT,CARDAS,, Mundorf, Johnsons 4% silver very good 
And a best buy. Wire I use Neotech 0- Crystal Copper Teflon wire .

Concerning the new ClarityCap CMR and CSA ranges, it would be a conflict of interest to comment on their performance relative to other brands. However, it seems fair to mention that these models are qualitatively different from other metalized film capacitors with respect to their copper litz end caps. This contrasts with other metalized film caps(e.g. Mundorf, Solen) that use traditional tin-zinc end spray to bridge the metal film layers at the capacitor ends. End sprays atomize and oxidize upon deposition, forming grain boundaries of variable impedance and phase anomalies that worsen with diameter. The performance advantage of a copper end relative to tin-zinc increases with diameter. This particularly favors use in applications involving higher capacitance and larger dimensions as found in crossovers.

I just finished replacing 6uf and 17uf MR with CMR in my much-modified Merlin VSMs. This was a big step up.

Thank you all for your opinions and suggestions for web site reviews. They have been very helpful. I will try to obtain some of the caps suggested for comparison.

Question:

For a tighter connection, I soldered with silver solder silver spades to the cap leads. After everything is connected, one of the caps does not work!

Now, I don’t know if the cap was dead from the get-go.

But, can the heat from the use of the soldering iron ruin the cap?

While I admire technology, I believe in results. I can take pretty much any DAC chip, put it on a circuit board and make it sound like garbage. Same for most technology. Beryllium tweeters, AMT, etc. can be implemented well and poorly.

I think knowing about the capacitor tech is good, but results are results.

And as always, let your own ears be the judge, not me nor a website.

Best,

Erik
