Avalon or ProAc?

I've narrowed my choices down to either the ProAc 3.8 or the Avalon Eclipse Classic. Maybe a used pair of Opus or Response 5's if I can find them. Any of the above choices would be run on solid state gear. Love a wide, deep soundstage but I'm very partial to a speaker that really images well. Anyone with experiences with any or all of the above choices I would appreciate hearing from.

Thanks
