First, smart to only amplify only the front three channels. But to give you a meaningful answer, far more information is required. Such as what room is available for additional components, your budget and finally what kind of speakers you have. Do you really need 200 wpc?
Based on what you have provided, here are my comments. Three mono blocks reduces crosstalk and gives each speaker a dedicated power supply. These obviously are pros. But they take up more room and could be the most expensive option. A three channel amp obviously takes up the least room, a plus. The downside is it probably shares the same power supply. Is this a problem? Maybe or maybe not as now you have to consider budget. I would take a Parasound HALO A31 3 channel amp over three value priced (Outlaw, Emotiva, et al) mono blocks any day of the week.
Without knowing any of these factors, room, budget, and speakers I would now suggest something even a little more radical. You said you want the system to do double duty for HT & Music. I am assuming that you are talking about 2 channel stereo music. So I would scale down your power requirement (the 200 wpc) and get a 3 channel power amp around 100-150 wpc and a separate 2 channel PREAMP With HOME THEATER BYPASS. This will really improve your stereo music listening. experience more than the extra watts per channel ever could. Hope some of this helps.
