As a condo dweller myself, I concur with Elizabeth. Get a good sense of your "New" environment first. This includes determining how well your walls are insulated, and the quality of your internal wiring and circuit panel.
You said you were moving into an "apartment" and so I will presume that you are unable to boost your inner-wall soundproofing or install dedicated 20amp wiring.
In terms of speakers, they don't necessarily have to be small if they are front-ported or designed to be "wall huggers." For example, Linn Majik Isobariks (which are not small) when placed on top of marble bases can work very nicely in a condo environment; Magnapan 3.6s, not so much...
Otherwise, plan on budgeting for surge & line conditioners (given typical apartment wiring) and wait until you have a sense of what kind of room(s) you'll be working with.
In my own condo environment, I'm running an Ayre Ax7e integrated with B&W 805Ds in the Media Room; Linn Akurate separates into Harbeth Compact 7es-3s in the Main Room; and a Naim UnitiQute into Linn Majik 109s in the Bedroom. I'm running Transparent Cable conditioners throughout, and it's no accident that all of my speakers are front-ported and 5" to 18" from their respective back walls. YMMV.
