I have a raspberry pi 4 with hifiberry amp 2 running volumio.
When connected to these speakers: https://www.definitivetechnology.com/products/aw6500 when volume is turned past ~50% sound starts to cut out and becomes non responsive.
When connected to these speakers it seems to work fine with higher volumes:
