Can’t speak on the difference between those two, but I have a Marantz sr5015 that had heos streaming on it. Recently bought a Innuos pulse mini. The difference between the two was enormous, can’t say enough about how much it is. Aware of the price difference, just that it’s worth the wait to save, and get a quality streamer. I was seriously considering the Marantz streamer, then Bryan at Olsens Hifi steered me towards the pulse mini, sure am glad he did. Enjoy the sound.
