I'll keep my question short and simple and expand it later if necessary:
When using DFPlayer's built-in amplifier by connecting a speaker to its BTL output pins, does it produce any power-down noise when you switch it off, especially if it has a large capacitor at its power supply pin?
(I'd just try it and see but I don't have the module with me now).
