I would opt for a beomaster 5500/6500/7000. These are more than powerful enough to push all of those speakers. (I used BM5500, now a BM 7000)
These are really superb units with plenty of power and easily available 2nd hand and worth the small investment. They have the optional advantage that it's easier to connect other (both B&O and non B&O) items to, like cd players etc.

I tried a BC9500 which I found limited to pull a full MCL system. 

Their should be a small-ish white box in each room, though I know some people have them actually built into the wall .... 
The dial could just be a manual dimmer for the sound mounted between the mcl2 box and the speakers (I used to have one like that in my bedroom) Makes the room controllable manually and I guess avoiding investment in an extra remote for that room. 

The black box (MCL2p amps should not be necessary imo).  Fun is that you can use a BL1000 remote to control the system in every room.

And yes, at this point I am pretty set on getting a B&O system.  It seems to be much easier.

I can full suggest the systems I mentionned.

The amount of speakers is irrelevant ... the total wattage pulled by them is.

Also in a system like that, it's unusual to switch on all the speakers full blast all the time.

Yes, I cant imagine we will have all speakers blasting at once.  After thinking about it I believe there are 14 speakers total.  Do you think a beocenter 9500 would easily handle most of these speakers playing at medium volume or 5-6 playing loudly?

rhansen, where are you located?

I am located in northeast Nebraska.  And I am sorry but I dont recall if the box looked similar to the picture you sent me.  I only really remember what was behind the volume dial.

Argh, too far!

I understand. Spend some time this weekend and find out just what you do have. Maybe snap a few photos and we can all piece this together for you. 🤒

Beocenter 9500 is rated at 2x85 watts at 8ohms
Beomaster 7000 is rated at 2x110 watts at 8 ohms. ( Is what I remember but you can look it up on this site)
My beomaster can perfectly handle 4 pairs of speakers without breaking a sweat ....(I don't have room for more speakers..) so I think 6 sets would be feasible.  

Like I wrote before, it depends on the power used by the build-in speakers.  For example : 2 pairs of 60 watt speakers vs 1 pair of 120 watt speakers ...
One of the other reasons I go for the beomasters , beside being more powerfull, is that it does not run as hot as a BC9500 in a MCL system.

Also maintenance (and possible repair) costs  are a factor in this setup imo. 

I think I am finally coming to understand the system thanks to all of your helpful info.  So, knowing that I have 14 speakers in my house, with 3 transcievers.  I understand that a beocenter 9500 or a beosystem 7000 will work.  Which do you recommend? Thanks again

Beosystem's hart is a beomaster. 

I love the beocenter 9500/9300 for it's design, but beware buying second hand as ofter the cd player is need of some work, the tape deck will need new belts and the glass panels often come loose. Not to speak of the 2 doors coming off tracks during shipping.

The beosystem 5500,6500 or the later 7000 all have the beomaster as main amplifier. Build like a tank (weighs as much too....) they go for little money 2nd hand and to me are the best value for money..... though a more 'conventional' kind of system and less design.
