Heyt thanks @Steve1 (Nice to see a fellow Aussie around these parts)
Its exactly what I needed to know. Im not intending on syncing more than one unit - I actually need a preamp thats controllable by Home Assistant and this seems to be one of the very few options available for us that run integrated amplifier setups.
Me personally I run a Turntable thru a RIAA preamp and a TV w optical out.
ALSO - can I control the volume level and source selection of an A50+ through Home Assistant? I couldnt find any reference on the A50+ product page that suggests it supports linkplay.
Yes this works e.g. with media player card. You need to manually add section to configuration.yaml as specified in the documentation to have the source selection list right. I added linkplay integration using HACS.
