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

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

I have had all Jensen caps the ceramic body is  very open and detailed themost 
neutral of the Jensen Copper foil caps. The Copper body in my opinion sounds the Most natural  with a very extended but richer upper end.great for Solid state equipment  the ceramic you may or may not likebetter 
In a tube circuit.

My experience is the Jensen’s, in tube gear and dacs, are just darker than the Jupiter or Duelund copper foil caps. I also modify and upgrade gear for a living and do all manner of upgrades with caps. Jensen are good caps, but not as good in the micro details, resolving , and air as the Jupiter copper foil or Duelund. These areas seem to reflect the sonic need of the OP so I am specifically talking about this “presence” area of the spectrum. . Vcaps copper are also more extended and resolving.

A good option, keeping what you now have, is to bypass your Jensen with the Duelund pure silver .01uf bypass cap from Parts Connextion. I have had great results with this combo in electronics. You will definitely get more air, sparkle and resolution. More realism!

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

Granny ring I agree ,I use the Duelunds as my main best seller in my Loudspeaker Clarifiers a bit pricy $100 each but ,give them a solid 200 hours and they truly do open up the soundstage and micro-details
