ATC SCM11 vs Monitor Audio Gold Reference 60

I was at Rocky Mountain Audio Fest last year and heard a pair of atc SCM40 speakers that I was very impressed with. They reminded me alot of some expensive pmc's I heard and loved in the bryston room the previouse year at a fraction of the cost. I currently am running Monitor Audio Gold Reference 60 towers which I love. I found out last month I am having a baby in sept and will be moving in with my girlfriend and her 3 year old son so I have decided to sell my amp pre amp and expensive mit xlr interconnects and will be going to an onkyo 805 reciever, with a rega apollo source.

My question is this... I am debating whether I should sell my M.A. towers and get monitor size speakers specifically the atc scm11. My theory is monitors will give me better imaging and soundstaging off a receiver then the towers will, as well as being better matched on power, I am also running a custom built 15" sub with 1000w going to it with full bass eq.

I have no way to demo the atc's before buying and I was hoping maybe any one had heard both these speakers, Do you think I would be happy with the atc's coming from the M.A. Golds? would it be a transition I would be happy living with for the next few years. Or would I be better off to keep running the Golds off my onkyo, possibly indefinately? I'm hoping that in a few years I may get a pre/pro and 5 ch amp but not sure if I will be going back to a dedicated two ch system anytime soon.

I mainly listen to classic rock, 80's rock and modern rock. my future listening habbits will be movies, xbox, and jamming out while doing house work and yard work prob not to much sitting in sweet spot and "melting" into the sound like I used to.

Thanks for your advice
