system number 2

Honestly you could pick any speaker that appeals to you. I can't think of a speaker that you couldn't drive. Even sensitive speakers may do well with more than enough juice as long as you don't mind not having a lot of play on your volume knob.
What this does allow you to do is try out a speaker you may have been interested in if your budget permits it. BTW what is your budget?

Focal Electra's first series has come down significantly, I set a friend of mine up with a pair of 905's and they sang quite well.

Personally for a budget system Id like to look for the product that put a company on the map, or a companies first effort into something new. Its when they have to work hardest to actually impress the public and give them a reason to actually pay attention to them instead of the guys with giant advertising campaigns.

Have you considered at all building or having a set of speakers from scanspeak or focal drivers? I really like the scanspeak drivers and have always loved focal's drivers.
