I have read that there are advantages to use several parallel (smaller) capacitors to replace a single bigger one in the HV filtering circuit, such as achieving lower total internal resistance etc. Would this argument also be applicable to the signal path or stage decoupling capacitors? For instance, should one use 1x0.2 uF or 10x0.02 uF? Which will be better for sound quality?

Neither. It's best to stagger values if you're going to parallel. In your example, it would be better to use 0.2uF, then parallel it with something like one or two percent of its value, like 0.002uF.
This trick is much more useful for power supply/decoupling than for coupling caps. If you think about what the coupling cap is doing (forming a voltage divider with a largish value load), you can see that there's no real advantage to trying to wring out the last couple of milliohms of impedance.
Sonic advantages? Very, very questionable.
