I'm aware of all of those features, probably should have been more clear, is there any sonic advantage of using RAAT over wiim dsp? I suspect I know the answer, but I don't know if there are any technical differences.Depend on what else your after. For me it’s not locked to a specific device and can be used across many more bits of equipment. I have many different makes and models and I have Roon manage them all. The interface is far superior no different looks to each service one unified layout, source agnostic for your library, better music management (Wiim has none), more DSP options over all and all applied at 64bit, upsampling, ability to use convolution filters for better Eq results, adjustable volume levelling, can build complex layers of DSP using procedural eq. Its multiroom is one of the best in class imo.
If you don’t care for managing your music collection in a specific way or you don’t need or use this stuff then there are other things around.
Personally I don't wish to pay for slick library management, nice UI or even knowing the signal path as thats a use once and forget feature unless as you say are connecting multiple devices and changing settings. I'm planning on adding a Yamaha receiver with built in room correction so will have no further need for upstream DSP
