None, actually, though I should have known that if someone did, it would be you...
I was looking for some information on sound processing (Specifically, if anyone made a compressor with an attack and release time in the minute range), when I ran into the FAQ sheet for this $2,000 or so doodad.
I swear, if it weren't for self-delusional audiophiles, there wouldn't be any tube production left.
Anyway, I hadn't heard the phrase before, and it sounded both cute and interestingly ambiguous.
