I used to live in Tokyo where my apartment was much smaller than my dedicated music/ht room at home, I had the same speakers, B&W 685, driven by a tiny Wadia PowerDAC 151. I was really impressed by this combination. They are probably the best bang for the buck speakers that I ever owned. The low end bass was amazing considering the fact that they were driven by a 15watt/chan DAC. I do think that the 685s can be much better if paired with something a little beefier and if I have to do it again, I would go with the same pair of 685 and a Peachtree Nova Decco 65. Hope this helps.
