Audiozen,
Does NASA use a lot of audio parts? To NASA, NASA-grade parts means reliability, not necessarily sound quality, and the best grade of parts is effectively a certification of existing processes and manufacturers, establishing provable reliability and consistency of manufacturing processes and supply. If you read NASA parts procurement guidelines, you will find that they in fact specify use of parts up to and including 'mil-spec' parts of a grade called MIL-STD 975 Grade 1. If you care to read that giant PDF file, you will find capacitor specs starting about 20 pages in.
I think, if you dig through both docs, you will figure out that any audio manufacturer which went through the process of finding good-sounding capacitors and matched them would probably end up with better-sounding and more appropriate capacitors than those taken out of a NASA engineer's parts box. If you read the guidelines and the MIL-STD 975M file and come up with different analysis, I'm happy to be corrected.
