One of the 'problems' you may encounter with bookshelf speakers is that even if the mids and highs were perfect the reduced bass would serve to emphasize the mids and highs making them seem bright or at least thin thru the mids. Many folks wanting fully fleshed out response incorporate a sub woofer OR find a small speaker with a 'bump' in the mid/upper bass frequencies. (Rogers LS3/5A did this quite nicely - at medium volumes, in a small room, it was hard to beat!).
I can't comment on the speakers you list. I've not heard them.
