“Roon is very demanding when it comes to resource consumption. Using one machine as roon core and streamer is not the best approach.”
I beg to differ. If Nucleus and Mac-Mini or similar devices is your reference, then the answer is YES!
IME, it’s the subpar and lazy approach in the design and implementation of most ROON compatible devices that leading us to believe that a single device serving as Roon core and end point is not optimal. To name a few, take a look at Taiko, Pink Faun, Grimm Audio and Merging Technologies. All these are prime example of how both Roon Core and Renderer can co-exist in a single device and yet yield to a sublime streaming audio experience, provided your rest of the system is up to par. I am just amazed by my Merging Technologies +player abilities to render captivating streaming experience, all from a single box.
I hope designers at Lumin and Esoteric take cues from aforementioned brands and eliminate the need for external computer for Roon Core, it is not at all necessary based on my experience with +player.
