Think of the MC200 set to variable output as acting as its own preamp. So you only need a power amp (or an active speaker which of course contains a power amp). Getting an integrated would mean duplicating the preamp and volume control part.

On the other hand, if you have multiple sources in that zone and need switching, then get an integrated plus passive speakers, or a pre plus actives, or a pre-power plus passives. In that scenario you would switch the MC200 to fixed output, and would lose iPad control of volume in that zone.
