Just got mine in the mail. I can't believe how good it sounds. Even just putting all the knobs at 12 o'clock sounds good. Very satisfied with my purchase.
Got a THR10X delivered last week from Sweetwater and had to send it back. It must have been defective. If you had the volume above 11 o'clock when playing it would turn itself off. It would do the same thing with the AUX/USB volume when playing an IPOD through the unit. Didn't matter if it was running on batteries or plugged in. It did sound pretty good though.
