Here is how to calculate the frequency of the tank circuit.A 0.335 Henry choke and a 5uF cap gives a resonant frequency of 120hz, which is the frequency of a rectified 60hz line. You could trick it in to addressing the rectified line hum. Two 5uf caps in parallel will create a low pass filter as well, if the resistance to ground is greater than 2000 ohms this is OK, less than 30hz, but if the path to ground is less than 2000 ohms it will let frequencies around 60hz and above into the circuit unimpeded. There is also the noise leakage through the cap as well.
Yes, people use noise to make things sound more exciting.

I have encountered people confusing high levels of upper ordered harmonic distortion as "speed" or "good transient response".

I was guessing that, thanks for explaining.
