Sorry to say I don't have any experience with the equipment you list, but it sounds like you're giving up on the Node 2i before you've heard it. I'm not sure if you have a trial period with that piece, but maybe give it a fair shot before moving up in price point? Since the Topping is a fairly budget piece, the Node should be an improvement.
That said, the Marantz unit offers a lot of features and flexibility for the price so long as you don't rely on wireless features long into the future. Wireless = eventually obsolete. For the roughly $500 additional dollars, ask yourself if you're buying features or sound quality. If features, ask if any are those you can live without when the next tech wave hits.
Best of luck with your journey. The Dali speakers looks like a great start.
