Okay, I am back.
But, it seems a lot has happened since I last chimed in.😮
So,
I wanted to have both my office and living room systems playing simultaneously the same music.
I thought Aurrender would be the cure, but, alas, no.
So, I got the Innuos Zen Mini for the office, and the Innuos Zenith for the living room (main system). Setting everything up, I had a choice to use Roon. Being a frugal (cheap) person I was hesitant, but, then thought, What the heck give it a try.
Mind you, I had Bluesound before.
It worked very nicely, and even though I had to work out some issues (which Bluesound helped to rectify), it was a very nice situation.
Moving to Roon was quite a pleasant change. A sleek piece of software that is very easy to work with and offers a lot of sound 'improvements' (DSP, for example).
So, to answer the question- Do I need a Roon Core?
From my experience, no.
You buy the Roon software licence and then set up your system.
Works like a charm for me.
(BTW- I was using an Ayre QB-9 Twenty with the Innuos Zenith before moving to the Brinkmann. I never had any issue with Roon during that change up).
