My replacement SA-10 is *FINALLY* in my system, breaking in. It already sounds way better than the first one I received, but I'll wait a few more weeks before I give it my final assessment...

However, it still had the same problem playing files from a USB flash drive as the original. After a lot of detective work, & a happy coincidence, I came up with a fix.

Here it is, in case any SA-10 owners run in to this problem:

Marantz SA-10: Fix for USB Flash Drives (Mac users only)


There is an SA-10 issue that affects people attempting to play music files saved on USB flash drives by Apple Mac computers.

As the Marantz manual states, “This unit is compatible with USB memory devices in “FAT16” or “FAT32” format.” Those are both Windows-only storage formats – they are not native to Apple Mac computers. But the Mac can easily format a flash drive to the “FAT32” format using the “Disk Utility” app that is pre-installed on all Macs.

The problem arises when the Mac copies music files to a flash drive formatted in the Windows “FAT16” or “FAT32” formats: the Mac creates additional, hidden files, with identical filenames, on the flash drive in order to maintain Mac compatibility. These hidden files are called “AppleDouble” files. When you plug the flash drive in to the SA-10, it “sees” these additional hidden files, which are not music files, and malfunctions.

Unfortunately, even turning on the “see invisible files” setting on the Mac will not reveal these “AppleDouble” files, so there is no direct way to see or remove them.

The solution is to download a free Mac app called “Onyx” https://www.titanium-software.fr/en/onyx.html . Note that there are separate versions of Onyx for each version of the Mac OS – you must download the correct version! There may be other Mac utility apps that provide the same functionality, but I can confirm that this one works.

Each time you copy music files to the flash drive, open the Onyx app, select the “Files” tab at the top of the window, & then select the “AppleDouble” tab from the tab bar below the main one.

Click the “Select” button in the lower right corner, & choose the USB flash drive in the selection window. The “AppleDouble” files will immediately be deleted from the flash drive.

As the very next step, eject the thumb drive from the Mac before leaving the app.

The “AppleDouble” files that cause the SA-10 to have problems will be gone, and the flash drive will now play properly on the SA-10.

(Warning: DO NOT use any of the other functions of the Onyx app unless you know exactly what you are doing: it is not designed for casual users, & you can create serious problems on your computer if you mess around.)
