I plan to purchase an N100H. Do I need to use AMM?
No, you do not need AMM for the content inside an N100H. After you finish copying your music files to the internal 2TB HDD inside the N100H, the Aurender software will automatically process the metadata* (cover art, file names, etc.) and present it on the iPad App after the process finishes. It can take a minute or an hour, depending on how much content you copied, and how much content is already stored on the Aurender.
*Note that the files must be properly tagged with metadata in order to appear correctly on the Conductor App.
