+2, Conductor App from Aurender
To Roon or not, it squarely depends on your choice of hardware. Majority of the hardware providers has taken an easy way out of not developing their own app interface and chose to adapt Roon.
For that matter, I admire Aurender for not giving into Roon and developed their on very robust and straightforward app that’s easy to follow. Yes, Roon has an advanced but complexed interface but when I am listening to music, I don’t care for none of that! I just wanna queue up music and listen. For simplicity and layout, I prefer the Aurender Conductor app over Roon by a mile. I don’t use any of the DSP features in Roon either. IME, Aurender’s Conductor app is very faithful to original source and doesn’t manipulate digital bits like Roon.
When Innuos users reported that Innuos Sense app sounds better than Roon, I wasn’t surprised at all. So my suggestion would be to choose wisely as app software is just as important as choosing the right hardware (streamer or server).
