@jfrmusic, I suggest you ask Vince from MSB what word clock cable you should use between the Aurender N20 and the MSB DAC (highly recommended). Change the Conductor App word clock setting for the N20 to use the word clock option.
I also suggest you ask your Retailer what hard drives (including sizing for your albums) they recommend for your Aurender N20 to include explaining the Aurender N20 Conductor App hard drive format instructions. Your Aurender Conductor App includes a Remote Internet Technical Support if you have any issues. This allows Aurender to connect to your unit, if needed.
Please discuss with your retailer and read the on line Aurender instructions for transferring music files to your Aurender Music Server to include how to handle the album cover art. Aurender Music servers scan locally stored files for embedded artwork. If there is no embedded cover art for the file, then the scanner checks the folder the files are located in for a "folder.jpg","cover.jpg", or "front.jpg" (".png" files work too) image associated with the files to indicate a front album cover. When neither of these criteria are met, the software will display a generic image as album cover art. Unfortunately, some media software programs such as iTunes handle cover art much differently. Instead of using embedded album artwork tags, iTunes uses "sidecar" files containing album cover art and other metadata. Unfortunately, this data is not relevant or viewable outside of iTunes. This process is a little complicated so please confirm everything before you start the actual transfer. I suggest a test of loading 10 albums before you transfer everything.

I suggest you connect to QoBuz first to ensure everything works and sounds great. After this, you can deal with setting up your hard drives and loading them with content. Please scan the Conductor App settings to ensure your settings are correct for your application. I hope this helps.
