I am very pleased with the Roon Nucleus+. It allows you to rip every CD and other digital files to its HD, plus stream high res audio. I operate it from my iPhone. From my experience the investment in nucleus is far superior to running the Roon software on a computer. But it is an investment. Another plus, the Roon Arc software allows user to access their Roon library from anywhere with an internet connection. I literally accessed mine today during a 4 hour drive. It’s awesome.
