The 3x is almost a perfect instrument in my eyes. It's a shame I play so many venues where i really NEED the speakers. I'm at an Atlantic City casino this weekend, and the load-in is horrendous .... I have to travel ultra light, and the 3x would not cut it there. PA900 on a stand, Bose at my side ... quiet, compact and quick in and out.

The 900 does have the MP3 volume ... I have it at max. I'm working backwards with this keyboard - turning everything else DOWN to get the voice and files to come up where they belong.
