In all probability if your goal is to recreate the magic you heard at the dealer you will fail by a significant margin. The room and its interaction with the loudspeaker is the single most important aspect of getting great sound. Most dealers have spent more than $100k exclusive of equipment just to get the room right. As a non-professional user you don't have to go to that extreme, but a basic understanding of room acoustics and the use of products and techniques to address common problems is very important.
The magic of hearing well reproduced music is not primarily a function of equipment. Instead it is more about correctly setting up and matching equipment. For less than half the cost of the system you heard at the dealer there are knowledgeable audiophiles who could assemble and set up an equally magical system. B&W and McIntosh are both very good companies, but there are other brands that offer better value. This plus the knowledge of how to properly setup equipment, particularly loudspeakers, can save a consumer money.
I have no opinion about the B&W loudspeakers you mention. Tboooe has extensive experience with that brand and I believe he has given you some good advice.
