A week ago I started to consider buying an Aurender to replace my NUC/Roon setup. It turned out to b an easy decision. The sound quality of the Aurender blows away the Roon setup. More detail and a richer overall sound.
I actually think Roon's sound quality has worsened over the last few years. I have also had an increasing number of connectivity issues. It may be the result of so many processes going on within the software itself. I look forward to the simplicity of the Conductor app.
