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've had good results with both the Jupiter cooper foil and Miflex copper. My Preamp called for a 2.0uf for signal cap in each channel I had already changed out all the caps in my speaker except for rear firing tweeter which called for a 1.0uf. So just to experiment I bought 4x 1.0 Jupiter and 2x 1.0 Miflex. I installed both the 2 Jupiter 1.0 to make a 2.0 per channel in Preamp and 1.0 Miflex in tweeter then ran them 24/7 for 3 weeks. Then I started flipping them around. I put a combination of Jupiter and Miflex in each channel in the preamp then back to all Jupiter in Preamp. I prefer the Miflex and Jupiter in the preamp. With Jupiter/ Miflex combo the bass is fuller and tighter to my taste. The Jupiter/ Jupiter combo was very nice also just different. Both combinations made cymbal sound right for the first time and both sounded very natural and refined. The preamp uses 6922 type. I did find with Jupiter/ Jupiter combo it liked the amprex orange globes which is a more analytical tube than the amprex bugle boys to me. Miflex Jupiter combo liked the bugle boy and orange globe.  Both combinations liked the Amprex SQ gold pins. Mullards and Valvo's were fun but depending on recording.could get a little boring. I did put Miflex 0.1uf as bypass cap in main tweeter 8.2 cap but with all these caps installed I have no idea if they made a difference.
