Victor my friend, I see you've caught the upgrade bug -- there is no stopping now.
If you generally like the sound of your current setup - B&K (I forget the model numbers) with B&W cdm1 monitors, you could look into a pair of B&W 802 Matrix 3. The specs for the current model of 802 look very decent (8-ohms, 91-db, Freq Range: -6dB at 27Hz and 30kHz). There are several pairs on sale at this sight. A couple of them are offered with sound-anchor stands for around $2K.
It might help if you specify the model numbers (or specs) of your amp/preamp.
