Only you can answer that question, with a home demo - however, a Marantz amp shouldn't do room shaking, and neither should the Dali, I mean it's not like they have 12 inch woofers. Marantz + Dali make for a very balanced partnership, imo, with nothing sticking out like a sore thumb. But again, only you can decide if it fits.I do like those Oberon 5s. Seem very classy. My only gripe with them is they’re floorstanders and if I was to put them upstairs wouldn’t they shake the house a little too much? I cannot express enough how much I’m looking forward to trying all this kit out. Hopefully soon I can.
