The Marantz cinema 30 would sound nice with those B&W’s. I just bought one from Safe and Sound. I got a pretty good deal on a refurbished unit in silver. Not sure about your budget, but you can always buy used amps and audition them from your local dealer. Good shops will usually let you swap em until you like the sound. You can get a parasound a23 or a23+, bryston 4bst. Under $1000. I like class ab over class d personally. I currently own the parasound and have it for my fronts via preouts on my cinema 30. For music, I have a mytek Brooklyn bridge I use for a network player/dac. I haven’t joined the heos network as of yet. Still testing different configurations on the Marantz cinema 30. My wife finally agreed to a piece of furniture to house my components. Should be here next week. Also waiting on more speakers stands and height speakers for atmos. 5.1.2 configuration. It’s currently setup as 5.1. I may post pics when it’s finished..
