interesting read, explains why some ppl have found that have nude caps sounds better.
When he says "Air is only practical for the lowest capacitances" how low do u think he means by low capacitances?

Probably in the picofarad range.

Personally, I'm waiting for someone to develop a foam teflon capacitor. Dielectric constant, say, of about 1.6-1.7. Anyone feeling so inspired? Think Mupor, Porex, GoreTex ...

Foam is not a good thing unless you want a microphone.

Air variable capacitors -- like the kind used in old a.m. radios -- had a capacitance of 365pF per bank -- of course when I was growing up it was mmF, not pF.
