impossible to answer, it really depends on what you want from the speakers.
i chose some tannoy DC4 because i wanted midrange and soundstage with fantastic vocal performance (on some recordings it's bloody freakish, speakers vanish and it's like there is another mouth in the room, "pinpoint" indeed), and for £245 delivered they deliver this in bucket loads, but of course there is a trade-off, and that is they don't do bass as deep as other speakers, even cheaper ones, but what bass there is is clear and articulated well.
From your list i would vote for the diamond 10.1, they are very able speakers and are very competitively priced - and the only ones I've heard on the list :P
