I haven't ever played an Orange of any sort, but if that's the feedback you're getting from it that sounds great to me actually. I'm not a big fan of Mesa, so I'm trying not to be too biased, I just prefer that tighter and crisper sound as you mentioned over the low heavy stuff like Mesas. That could just be me though. I think one of the best cabs I've ever played, or maybe it was just the amp, which was the same brand, but it was a VOX, and it had surprisingly great tone for a brand that doesn't usually specialize in high gain/metal style playing. They're affordable too if that's any sort of plus to you. I used to run it a tube screamer with it, but it's not completely necessary. To answer your question though, I'd give the Orange a try. If you don't like it, sell it and try out a mesa.
