i have been using Roon for three years.
The longer you use it and learn how to manipulate and discover your own and the wider music catalogues, the more pleasure it gives.
there are lots of layers and a month might not be enough to really understand what it can do.
Music library’s are getting bigger and harder to manage and organise. Roon sorts this out for you and makes musical discovery and rediscovery an effortless pleasure.
My advice is to forget the trial, rent for a year and then decide if you want to buy.
i suspect any perceived differences in SQ that may exist between Roon and Audiovana are down to the particular hardware implementations in those specific systems with all their variables.
