Jupiter Copper Foil, Paper & Wax Cap Versus Jensen Cap 0.10uF 630Vdc Copper Foil Ceramic

@johnss @atmasphere @grannyring
Thank you All for your comments and suggestions. I really appreciate it.
I am also considering the Mundorf Supreme Silver Gold Oil capacitor 0.10uF 1000V ,
Has anyone experienced the Mundorf’s? The Dielectric is Polypropylene.
There own Mundorf description says, "These unique characteristics offer a capacitor type of equally unique musicality: finely nuanced and lively shining acoustic colours, which combine into a breathtaking, beautiful, live-like music experience with the utmost precision, presence and three-dimensional plasticity."

Does the higher voltage rating improve/change the sound compared to the 630Vdc of the Jensen that I am replacing?

Thc so much, Bob

The Jupiter Oil Caps are way more open with much better detail in my opinion and are a better build quality again my opinion.

Thank you @bigkidz for your comments. Sorry if I am a little confused about your statement. Which Jupiter Oil caps do you mean? Are they still in production or do you mean ’bees wax’? e.g. Jupiter copper foil wax & paper.

"The Jupiter copper foil had too much emphasis on the mid-range so it gave the impression of a thicker sound more musical sound at first"
Are you meaning the The Jupiter copper foil wax & paper are thicker sound in the mid-range?
Thx , Bob

Thank you both for your comments and the detailing your experiences. Its most helpful to me.

Thank you @audioman58 
I have settled on the Jensen Copper PIO ceramic body. I have have them installed and I agree that they are quite neutral. The midrange and bass are pronounced. I would like more of the high frequencies - as the caps get played in, should I expect to get more high frequencies?
My tech also changed another cap in the signal from a British cap (don't know the make) to a blackgate. I am wondering if the blackgate has somehow reduced the high frequencies. My tech said he thought that the blackgate would provide a more overall even/balanced sound. I can always change it back to the British cap.
@audioman58 Do you think blackgates 'open up' more in the high frequencies as they play in? Or is their characteristic one of less 'highs' and more 'lows'?

Thanks so much any comment you may offer.

I decided the OIP was a better choice especially due to my analogue ’all tube system’.

@grannyring
Thank you.
Do you have any experience or thoughts on whether the Jensen PIO Copper Foil Copper Body would deliver more high frequencies - extended highs -than the ceramic body?
Thx, Bob

Thank you both for your comments and advice. That's a very interesting comment re: bypassing with a Duelund -01 bypass cap.
Thank you, Bob

Yes, I definately would like tom add the chararcteristics of the Duelunds a the Jensen are 'dark' and I am missing the higher and extended frequencies that i enjoy. 
The bypass caps are still $100 each and I am wondering whether to just go the whole hog and purchase the Duelund Capacitor 0.1uF 630Vdc CAST-PIO-Cu (Sn).

How close would the Jensen plus Duelund combination come to sounding as good as the Duelund Capacitor 0.1uF 630Vdc CAST-PIO-Cu (Sn)? I think this is where my final decision lies.

Thx, Bob

Thank you!
I will read up.
