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

Greetings,
Your advice and comments would be most helpful and appreciated.
I will need to change my current capacitors in my tube power amp as one of my current Jensen 0.1uF 630V Copper Foil, PIO, Aluminium is now a problem - caused a EL34 tube heater to glow red. I will need four new capacitors.

I am considering two possible replacements:

1. 0.1uF 600Vdc Jupiter Copper Foil, Paper & Wax Capacitor   
2. Jensen Capacitor 0.1uF 630Vdc Copper Foil Ceramic Case 

Any comments on how these compare in their sound characteristics?
I would like a cap that offers balance across all frequencies, control, richness, enticing tone, and transparency. Also ease of flow of the music.    
Thanks so much, Bob

I put Jupiter VT 8uF to LPF crossover.
The break-in period of large capacitors takers a lot of time.
I burned it in cable burner for 3 days fist. But after that it sounded very dull.
Then, I burned it other 6 days. Now it sounds much better.
But I steel anticipate much more transparent and vivid sound.
@grannyring , can you enplane, how is the sound of Jupiter capacitors changing during burn-in?
People without patience (like me) can do wrong decisions...

I never tried Teflon capacitors.
But I tried a lot of different polypropylene from different producers meta-lased, film and foil.
All of them sound bad for my test. Synthetic, flat tonality, not natural, not musica,l not smooth not organic,...
I wold prefer any paper in oil type capacitor to any polypropylene capacitor.

Alex.
