Hi Dgarretson,
A few pages back I wrote about a sort of bypass-experiment in the tweeter section of the magnetostatic Apogee Scintilla with its two, highly revealing 1,5 m tall and 0,5 inch wide, pure aluminium foil tweeters.

My experiment differs a bit from the more common "single, small-value bypass cap"-experiment (that most of the time uses different caps for the bypass and main cap), as I experimented with multi-parallel caps of the same type/manufacturer. I experienced that this configuration made a very (!) significant improvement over the single value cap (same type/manufacturer as the ones used in the multi-parallel cap). Further I noticed that multi-parallel caps using different kind of caps lead to bad results.
It is a pity that I haven't read so far on this forum of someone else doing this same experiment, as the improvement is not small and the costs are very low. In my earlier post I mentioned that I would not be surprised (based on my experiences and Tony Gee's captest) when the Obbligato cap performs in about the same level as the best Mundorfs when used in multi-parallel configuration.
