Maybe we're saying the same thing as each other.
Perhaps, the post I was answering specifically questioned the as yet undeveloped feature found on the product road map, very clearly that is transcoding on-the-fly
by the endpoint, and the WiiM devices can't currently do that. I wasn't saying the WiiM devices aren't ultimately capable, though I do suspect the Mini model is probably lacking the necessary available system resources.
As for classification of WiiM as an Endpoint or a Server, LinkPlay has deployed quite the blend of Features usually considered the purview of either/both device classifications.
Not in the context of what were are talking about here though, so far only the WiiM Amp can act as a server, the Mini, Pro/Plus are only endpoints from the perspective of what the post I was responding to was questioning, that being the product road map feature of endpoint transcoding on-the-fly. As I stated above, I hadn't made any mention at all of the WiiM Amp, or the WiiM Amp as server and whether that could be made to do the transcode, you did. The question I was answering did not involve that kind of setup, he wanted to know if the forthcoming Ultra model (this is a thread about the Ultra) could play native DSD due to having a compatible DAC chip, or transcode DSD on-the-fly via USB output.
There could be it wasn’t used much by many users and waste of their time working on something that only handful use them.
Well no, it was never used by any users at all because it was never actually supported, only placed on the product road map at some point nearly 2 years ago. WiiM wouldn't have bothered (wasted their time) adding it to the road map had there been only some tiny handful of requests for this feature, however I do agree that DSD anything is a niche use case and since this is easily handled server-side by LMS, Roon, and DLNA/UPnP servers, it is effectively a non-issue for most (including me as I use LMS). That said, I was simply answering a question posed by another member here, not making some big important use case, or demanding this feature be added.
Since this is a thread about the WiiM Ultra, let's just let this discussion go now. I've adequately explained myself in terms of the answer I provided to the original question posed, there's no need for any more needling about it. That original question was confusing because it conflated the use of a DSD-capable DAC chipset with actual WiiM firmware compatibility, not to mention it referenced use of the USB output, which would of course bypass that DAC chip altogether.
