I don't use arc often, I don't see the point of it against better offerings.
I am becoming aggrieved at just how shit roon radio is, its giving me nothing, nothing new, I can literally tell you what I am going to hear next and in what order.
However, the multi room stuff from a variety of hardware keeps me hanging on. I wont lie I keep an eye out for alternatives that can do all of this, but have not found anything yet. The circa 30% increase in price has helped my desire to keep looking.
I am struggling to see any real development in roon, which is a real shame, the requirement for 100% on time with internet is a concern.
Stability rock solid in terms of the server running in docker. Not so much as an endpoint on windows where if you minimise it for more than a few minutes it will crash. Search can be a tadge slow at times, no doubt connected to the always internet connection requirement.
I still like roon. lol.
