A Beomaster 4500 would match the looks nicely (as Beocenter 9300/9500, if you want a complete all-in-one setup) but they are usually a bit pricey.
Beomaster 6500/7000 would suit fine as well, if you're more into the brick form factor. All of these have the Powerlink speaker outputs which are the optimum connection for these speakers.
But be warned, there's no end to it once you begin It's a virus...
