To be fair and frank, the SGM is not just a "server" at that price. Its a powerhouse ultra-low noise computer that can handle the Bloatware hog of Roon while upsampling on the fly with HQP...both of which are resource hogs. People are buying it for that with the caveat that it gives the SQ they want. Whether the EVO with the 432hz tech is another way to skin the cat, I cant say...but it seems like they are aimed at different customer sets. I for one am glad to have MORE choice on the marketplace.
Well, if you want to be fair, as you write, you should not cherry pick in comparing one feature with another. Now, the fact you seemingly do not have a commercial interest, I am assuming this is a pure coincidence.
The EVO does have an option to change the ground frequency to 439, 438, 437 all the way down to 432. I personally don't use it though but quite a few customers seem to have this plugin activated.
EVO is as much Roon-capable. check the page with Roon partners:

HQ Player is a terrific upsampler costing 117 USD and integrated in the SGM. The EVO-engineer developed the upsampling logic (can be activated as well or not) which is not as feature-rich as the HQP but very straightforward with possibility to upsample till 24/768 for those that are in need of upsampling. Is it better or as good as HQP? No idea, I only reported before that the server (with all its implementation) was playing as good as the SGM (with all its implementation) connected to my Aries Cerat Kassandra Signature DAC. To which element exactly that quality has to be assigned at each brand is less important... they both were given the opportunity for a best shot.
On the 'powerhouse ultra-low noise computer': well, a server that plays that well evidently has its power house-keeping well executed, there is nothing special about that.
So, you DO have more choice in the marketplace effectively, happy you
