I'm new here. I'm from Belgium.
I'v just received my QA660. I use it with a QA100 amplifier.
I have a 128 GB SDXC Sandisk SD card. It's properly formatted (FAT32). When I start up the qa660, it see all the music I've copied on the SD card, but it seems to be blocked. At that point, the qa660 does not respond to any command.
I've tried to upgrade the firmware : v1.5, v1.6 and v1.0 Pure version but the problem persists.
I've also tried an other SD card, same problem.
Many thanks in advance for your assistance.
