I just bought it yesterday , it is amazing ! sound quality is excellence & loud enough for 100- 150 sqf listening area except you're high fever . also i test the mini before i make decision , The sound space and head room big brother is better than little brother , also big brother build with video output ,a very useful function when viewing Utube & video , the new software 2.1 is work with iphone now. I highly recommend to invest .
