Speakers for Jolida 302B?

I have a Jolida 302BRC and I would like to know what used speakers people would suggest upgrading to. I've looked at Quad 11L2's and 12L2's in the $300-$500 range used (and shipped). What else pairs well with Jolida? I'd prefer to spend less than $400.

Also, any suggestions on cables to connect with? I see Morrow has a sale right now.
