I have one and I love it, it is by far my favourite amp I've ever played through. However, as with most Oranges, it has the distinctive warm Orange sound. I'd definitely suggest trying one first because I there isn't a whole lot of control of the sound available, just a 3-band EQ and gain.
That's not to say you can't have it sounding clean- with the gain low and the master volume high it is clean, but a very warm, valvy clean.
You might want to try an Orange Bass Terror if you haven't already- same preamp as the AD200 but with a class D power amp and capable of going louder, cleaner (there are some reliability issues with them though, and they don't sound quite as beautiful as the AD200 in my opinion.)
