Hi Gary
I just got mine two weeks ago. Like you,I was hoping that the Bose would at least equal the Z5500 quality.It did and more. I took mine twice to the weekly dance with 20 band members.The PAS cut through clear as a bell at 1/2 volume,wheras the Z5500 could do it if I cranked on it. As you mentioned,the sound I hear is what the customers hear 100 ft away. Lots of compliments.
I bought mine without the sub as I use the Z5500 sub. Great sound.
