Thanks, but at risk of repeating myself, the ipad I have sports ios 12.5.7, which is insufficient to get hi-res digital streams from apple music. Being so old this ipad is incompatible with later ios upgrades. So to stream tolerable (CD) quality music into a hi-fi system, using an apple tablet and external DAC arrangement, would need a later ipad running - I think - ios 15 or above. ipads aren't cheap, hence thinking about Samsung galaxy tablets but am hesitant in case similar limitations exist in Samsung world.
