I still think a great pair of 500 quid standmounts plus stands will be better than any floorstanders of similar money. More musical, tighter bass and easier to position. Usually, but not always. I've never ever been a fan of cheaper FS, they always seem less enjoyable and far more difficult to position.
A nice little pair of Linn 109s might be a good shout, especially second hand. You could also dig out an older pair of dynaudios for that money too. I'd probably look in the classified section of avf / lejonklou forums etc
