For my MOX8... I don't need really LOUD, it's a small church gig, often solo keyboard and voice (me), but I would like decent fidelity, especially for acoustic piano. I played both systems connected to a MOX8 at GC today and I preferred the JBL over the Yamaha for acoustic piano. JBL is also lighter and less expensive, but Yamaha has some options missing from JBL, which I could *probably* live without. Your opinions, preferably based on experience?
