I do recall that at one stage, before someone here (Simon) showed me the light, I was ripping CDs directly to the Synology, and then copying from there to my back up locations (such as the QNAP). I don't know if that might be the cause. I also don't know if I should work my way through my QNAP library deleting all of these @ea directories and their contents. Some of them are several megabytes in size

Does anyone have any thoughts?

I believe these are thumbnail images that are created automatically by something in Synology DSM. You don't see these folders on the Synology because Synology DSM treats them as hidden folders. MinimServer doesn't use these images and there is no problem with deleting them.
