what speakeers are a good match with unico se

I recently bought a Unico se hybrid integrated amplifier. I do like it alot. But now I need better speakers. I'm using my old Vanderteeen model 1's and the Unico really made them better than I've heard from them before but it is a bit overpowering for the Vandersteens. I like a broad variety of music from classical and jazz to driving rock and even some country. I do not live close enough to easily audition other systems so I'm gathering suggestions to make a decision. I hear that Triangle's are good but bass shy, Opeera's might be a good match as well as Proac or Monitor Audio. Any comments or suggestions?
