Those look a bit hit and miss. They seem to use really old controller chips, which is a Very Good Thing(tm) because that means they very likely implement the old PIO protocols correctly -- needed by the empeg.

But they also seem to be limited to no more than 64GB size in SD cards, and probably don't work with SDXC or perhaps even some SDHC cards. Note that there's a cheaper branded copy of the exact same card on Amazon: https://www.amazon.com/Optimal-Shop-Digital-Adapter-Converter/dp/B00DGNYXQ0/

If I could get one here cheaply/quickly enough, I would get one and try it out. But Amazon Canada doesn't have any "local" options -- they all come on the slow boat from Asia.
