Streamer/Server to replace Innuos Zenith

I am looking to replace my Innuos Zenith mkIII. After the long anticipated wait of a few years for their own software and it is still a mess for iOS users I have decided its time to move on. What do you all suggest for something like the Zenith but hopefully a step up in sound quality? I still have a Roon license so I am OK with using a Roon based product.
Thank you
