I think you will be happy with the "vintage" Mac gear. It is warm enough and has autoformers so I think it will work with your speakers.
The set up is the usual "Cardas" triangle, which is simple . You should place the listening sweetspot at the apex of a triangle as follows. The distance between the speakers is the distance to the listener. As an example place the speakers 8 feet apart and your chair 8 feet away from the speakers at the midpoint between them. Toe them in as needed for best soundstage, in a trial and error fashion.
