I'lll just add one point which is often skipped over. You've already pointed out that "...the ultrapath capacitor provides a bypass to the power supply capacitor...". The bypass action works because the bypass capacitor impedance is smaller than the power supply impedance, so the signal current goes preferentially through the bypass instead. For this to work, the power supply impedance can't be too low. Look at the circuit below, and note the 100 ohm resistor between the power supply and the amplifier circuit. The 40uF ultrapath capacitor has an impedance of less than 100 ohms at frequencies above 40Hz.
