I recently went through the same process due to my relocation. My apartment is exactly the same size like yours and I ended up with the following:
Speakers: B&W 685. $500shipped used. Bought it right here.
Speakers cables: Transparent Musicwave Super Bicable. $400 shipped. Bought from Ebay
DAC/Amp: Wadia powerdac 151. $800 from Amazon.
Source: Sony PS3 with my USB drive connected. $300
I'm still amazed by the sound quality of the 685 given the puny 15w/ch from the Wadia.
Hope this helps
