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

Just out of interest: what‘s the problem on IOS? I have been using mine without any issues.
I’d recommend a Aurender N10. They upgraded their power supply circuitry about a year ago. Great sound and a control application that everyone likes. I have two Aurenders, N100 and WE20se. If you have the means I would, of course recommend the WE20se. When I bought it I was concerned it was worth it, after receiving it I realized it is a good deal for the money and what it has done for my system.
Take a look at the Grimm Audio Mu1, especially if your DAC is good with / optimized for AES.

A limitation of the MU1 is it’s USB output (at this time).
I use the PS Audio DAC With Bridge 2 for streaming and it is as clear as a bell. Quobuz streams through it and I couldn't be happier. Oh it's also a very fine DAC.
