OK, that's seriously wierd. Let's take this to the PM, so I can try to help you from there, alright?
thank you very much thats really appreciated. just to clarify literally same thing on both units straight out of a sealed box from your Amazon store and the line in and amp and bluetooth works but none of the rear switches or bass/3d button works on the sound. and like I said I've a/B both units to the one I'm sending back to be repaired so I'm pretty sure I'm not going crazy because all switches and buttons work perfect on that one im sending back repairs and you can clearly hear the change your amp makes to the sound especially on the sundaras. and in comparison on the 2 recent units literally not even a tiny db change as I say literally nothing no change in the sound...... but I still hear the amazing and clean sound your amp still makes on a defective unit which makes it hurt even worse because I love this thing when it's working thank you again and appreciate your time
