I've seen some tests that show that PIO caps have the most linear response of the common types. The polypropylene came next. The curve for the cermic caps showed a lot of hysteresis (i.e., it was curved). That might be a contributing factor.

The other thing is precision. The + or - value on caps varies a lot. The ceramics are usually + or - 20%. So if you've got a 0.02 uF cap, that 20% range means it could be 0.016 to 0.024. The 0.016 cap would be quite bright. I've read of some ceramics having tolerances as high as 80%!!!!

I don't know if either or both of these things is part of what makes PIOs sound nicer.
