Based upon your other MQA thread I decided to go to a dealer and get a listen for myself. During the demo I too noticed the blue light, but it wasn't steady, it was flashing. I ignored it at first, but after awhile I couldn't help but notice the the flashing blue light wasn't a steady flashing, but instead was irregular, yet some how not random. Half way through DSOTM I realized the flashing blue light was Morse Code! The message was "Help me". At this point I started to freak. Clearly The Music was being held hostage by MQA and needed help. I made my way back home and quickly unplugged by DAC -- it's non-MQA, but I'm not taking any chances.
