Ive been going back and forth btw the UL310 and UL410 w the UL501. I want the UL310, i like the small form factor and small weight, Ive had the Ul410 before and though its not big or heavy, its much bigger than the 310. Would the 310 be able to handle the power of the UL501? Ive read that the UL310 compresses and kinda dies a bit at high volumes.....Im playing medium sized rooms right now, and I usually have PA support, but sometimes i dont. I need a rig that i know can handle everything. Is the UL310 it?
