Help with shop set up

I am presently setting up a woodshop. The dimensions are 32x50. The wall height is 10' with a vaulted ceiling peaking at 17'. The floor is concrete, the walls are drywall. There is a loft at 8' high in the back that is 32'x 30, also insulated and sheetrocked. There will be a pair of garage doors on the east end. I would like to assemble a nice mid-fi system to listen to as I work. The amp I will use is a Bryston. The major reason is I like the sound as well as the advantage of the warranty. I would like opinions on a decent pre amp and speakers. The CD player is a Rotel 991. Should I use monitors or floorstanders? Two or four speakers? I listen to music at a moderate level. Not real loud. Mostly rock and roll and jazz. I've listened to the Thiel CS 1.5 and tne B&W N 805. I would just like some input as I am not a real serious audiophile but exhibit signs of the virus. Advice and opinion will be appreciated. Thanks in advance.
