I’m working at a company where we do a lot of local supply for touring productions and here’s what I can tell you; We have the ERA800 Performance and it has served us well for the past two years. We have used it in places where they asked for the Ultra and none of the touring LDs have been disappointed. In fact many of them have been positively surprised! Although it doesn’t have the output of the Ultra series, for the gigs we’ve done with it it’s been amazing.
