@KantoLiving I recently bought this off of amazon.ca sadly without seeing the drop and I was wondering if it is okay to leave on all the time in standby mode. I also have the same question for the YU2's minus the fact that it does not have standby.
The YURI is designed to stay in the "Auto" setting at all times so no worries there. The YU2 is also intended to stay on all the time just like most PC speakers. Enjoy the new sub!
