If your budget will stretch to a Unitiqute, go for it. Just one word of warning though, give it a wired Ethernet connection as its WiFi performance can be poor.
Marantz MCR611 should do the trick. My girls use slightly older versions for internet radio, spotify and streaming from a NAS. The Marantz App is quite good, which is very important.
The new models have good WiFi modules which seem to be robust, insofar as any WiFi is robust given the environmental and network variables that can always affect it. The old models including the Unitiqute the OP is considering are unfortunately not good with WiFi for many people. Personally I would always use a cable anyway, but all the more so with these old models.I agree with the poor wifi performance of Naim streamers and I would avoid if you are going down this route.
Does anyone know if the MCR611 is 5GHz wifi compatible? I've repeatedly tried to get it to connect to the 5GHz bands of both my VM Superhub2 and AirPort Extreme but it fails to connect to either, yet it connects to the 2.4GHz bandwidth just fine. An AppleTV sitting next to the MCR611 connects to 5GHz without problem.Marantz MCR611 should do the trick. My girls use slightly older versions for internet radio, spotify and streaming from a NAS.
