Thoughts on Michi P5 & S5 combination to drive Bowers & Wilkins 802D3, or 804D3 with subs

I'm contemplating adding a system to my great room, (34' W x 19'6"L open gable ceiling) and would like your thoughts on the Michi product line by Rotel ?  Systems use is to provide sound to the living portion of the home, Living Room/Family Room/Great Room that is open to the dining & kitchen space that goes beyond just noise, quality noise if you will, my wife, kid, and I, all would be users of said system across a wide range of music likes and dislikes.    I am very open to suggestions but need something that fills the room but its presence isn't over bearing.  The amp and pre-amp will reside within cabinetry already in place which may need to be vented for heat dissipation.   I've focused on these brands as I've had a great experience with them while building a home theatre with Rotel and B&W.   I'd like to hear what you'd constructively do instead or to enhance our experience - Thanks.   Budget is approximately $40K, all wiring is in place, and my time and labor are the installation crew.
