Try Genelec 8040, 8050 or Focal Twin 6 Be - all are designed to sit on a studio meter bridge and should sound great on a book shelf.
I have the Genelec 8020b as office desktop speakers and they are without parallel for their size (if you like precise sound) - for a bookshelf you will need a bigger model Genelec.
