I find that the Arylic gear is quite suitable for my needs as a constructor, they have a good range of DIY products which are adequate for my application.
It appears that Wiim only have a couple of product options currently, I think you will find that the most, if not all the extra items that the Wiim Pro offers will be available in the Arylic 2023 new product lineup.
I’m led to believe that Arylic R&D are also working on some new and innovative projects.
So for me, while the product suits my needs, I’ll stay here.
If I was going to start afresh I would go for something that is Roon compatible, there are plenty available from a lot of well known and high end brands.
In my case with DIY, I think that I would go Pi based with some kind of hat, of which there are plenty available online, but for me that’s not on the horizon at present.
