I have a Hegel H90 in my office system, and using Airplay from my iPad with Qobuz, it does switch the amp out of standby. One thing to note, it will switch to the Network input, and the volume may be quite high (34 in my case), No idea about Spotify as I don't use it.
Best to check with a dealer for the H190, but should have similar functionality to the H90, just more power and a balanced input.
Note the amp must be in Eco mode (Standby), available on the remote control, and not powered off by the hidden power button on the base.
