Hi and welcome to the Shack :T
Ref to your questions about changing the Anthem kit to either Classe or McIntosh, I see it as more of a sideways step rather than an upgrade as the Anthem kit is very good indeed, I would look more at the speakers being the best upgrade as the 804's are good but you could do a lot better, maybe up them to the new B&W 800 Diamond range?
Edit: just realised you have the new 804D's :doh: so maybe you could get a bit more from going with Classe or McIntosh but I do not think it will be a much better solution than you already have?, I would also throw the Arcam AV888 into the mix, try and get some demo's!
