on the desktop?

Hi all-

I'm helping a friend think about a system for her office. The room is small (about 12' by 8'), and the speakers will sit on the desktop. She will mostly listen to cds (and also needs a cdp and amp for this system.) Other considerations: she has small children, so speakers that sound nice at low volumes would be ideal. Her music taste is varied, but she listens to lots of jazz and classical. I was thinking about Harbeth P3esr (maybe run with a Wyred4Sound mint or a Rega Brio), or the Kef Ls50 with the Arcam A19. I wonder if anyone has experience with those speakers on the desktop in a small room? Or other ideas for speakers for this situation? (Component advice is welcome too). The budget is 2-5k. with many thanks! Margot
