jman,
I just bought the monitor 7's v3, as they have just came out with the v4 and were clearing out the v3's. Yes, the 11's are easier to drive than the 7's and 5's. With a mid 90's db sensitivity the HK can EASILY drive these speakers. I have a $200 kenwood receiver that is bottom of the line, and it does the job, not what i want, and will be replaced once i get more money. In terms of money, I got the 7's for 800 canadian after tax. So, if you can make it up here to canada, not sure where you are from, then it is quite a bit cheaper. I love the speakers by the way and highly recommend them.
