The Reliable capacitors are of good quality as I've used some in the past.Better quality caps do indeed help. I can vouch for the ppfx from Reliable also.
The higher voltage caps have a thicker dielectric. Why that sounds better I don't know. From my understanding of "break in" the thicker dielectric should need more time.
