Best small/monitor/bookshelf speakers?


I am wanting to update the speakers in my son's bedroom system and the ones at my office (older inexpensive Kef's). Have considered the newer Kef Q15.2, but haven't had the time or distribution in my area to check out all the possibilities..both new and used. What are you favorite speakers in this size range? Thanks for the help!

Hi Whatjd: What are the electronics in both systems and what is your price range again per system. The reason I ask is that the Tukans are great little speakers but require good electronics and cables to sound that way. They are also a 4 ohm load and do not work well with some amps. I have listened to tons of bookshelves in the past four months from $250.00 up to $1800.00 and may have some recommendations.
Thanks two you both for the responses. My post my be a little missleading. These are both secondary systems to may main one...and are not the highest-end by any means.. so perhaps the work Monitor should have been left out of the headline...anyway, my son's system is using a Denon CD player with an older Nak. Stasis receiver and older Monster M1000 interconnects..and some mid-level Monster speaker cable from the same vintage. The office is using a Classe intergrated and Straightwire Rapsody II for all wires... and both systems have rather inexpensive Kef's ...and I should look...I think they may be 102 of something....but had the chance to hear the little Q15.2 and thought they, or something in that range, would be a step up for both systems. Both of us listen mainly to Jazz and some Pop...and the office system has an older Sony ES tuner that I use to feed that system public radio most of the day..
I just picked up the Reynaud Twin MK II's and they are excellent, you might put them on your list.
