Which components will match B&W DM 309s?

[Arno007]

I want to expand my stereo setup to a 5.1 setup. I have a set of B&W DM 309s which work very well in my tv room. I would like to get the matching B&W 300 series componets (see my wanted add) but failing that, what else will work well? I have the Yamaha DSP-A590 AV amp which gives 70W per channel. I am on a smallish budget, so don't suggest over-the-top equipment please.
