I have a set of Focus 20/20s, and I have been all over the map with power amps. At the high point I was at 1200 watts/channel, and the low was 350 watts/channel. Actually I tried a tube amp rated at 40 watts too without much success.
The Focus are efficient which means they don't need a lot of watts. Case in point, the 350 watt McIntosh sounded WAY better than the 1200 watt Legacy Monoblocs in my system.
What the Focus does thrive on is current. Make sure your power amp/receiver can handle 4 ohm and lower loads. The more current you throw at it the better.
If you decide to get a set of Focus, rest easy in that you will have plenty of room to upgrade elsewhere in your system (electronics, cables, room...) and actually hear a difference.
Good Luck -
