Multi-Room Installation

Hi everyone

I am new here so I will give a little info on my situation.

I am a Canadian who moved to Germany (Freiburg, area) about a year ago with my wife of 10 years, who is from here. it looks like we are staying, so we are going to build a house, my German is not great and my wife knows little about AV and since she has been in Canada for about 9 years knows little about the companies that are around.

In Canada I had used A Paradigm Studio 100(mains), Studio 20(rears), ADP-470(effects), CC-470(center), Seismic 10(Sub) all v.3 with a **Yamaha RX-V1800 Reciever**A weak point I intended to replace** for the main system,

I had another 7 channel but smaller Paradigm(Cinema Series)-Marantz for the basement and a Peavy/Yamaha PA system for the Garage/deck we have a couple acres in the bush so no problems with neighbors


Currently I use a pair of M-Audio BX-8 connected to a PC I built here specifically for TV and BluRay/movie watching

Here is what I could use some help with.

I am looking for a company that could do a supply and install job like this. I would prefer to get it all from the same place.

I would like to wire the house for multi-room audio and some Home Automation and possibly do a medium sized home theater
I would like at least the Paradigm level of quality equipment.
Over the years I have owned many different brands as I like to try new stuff so I am not against trying a new European company if it is of decent quality.

This time around I would like to go in-wall/in-Ceiling at least for the the rears, and effects and of course the multi-room audio **I know cabinets are generally better but I would like a bit cleaner look**
As for the deck maybe something like a pair of Bose 251 or something similar.
I intend to have a sound room with a nice tube amp and a good pair of stand speakers.

I am trying to find a good company to do this with some home automation as well.
I have designed a room specifically for equipment in the house plans and we are currently looking for a builder and I figured it is time to pin down the AV guys so things can be planned accordingly

I would appreciate any advice I could get on this

Thanks Justin
