Is this a question or a bait @grannyring
From Innuos website:

ROON LIMITATIONS WITHIN INNUOS SERVERS
innuOS Servers currently use Intel Quad-Core CPUs which are powerful enough for music server duties whilst maintaining the system fanless and limiting the amount of power-noise polluting the audio system. The main task requiring very heavy computational requirements is the DSP processing within Roon. With the current hardware, upsampling CD-Quality files to DSD128 and DSD256 will not work properly. Upsampling CD-Quality files to DSD64 works when this DSP setting is being used stand-alone, as well as upsampling to PCM 384KHz. Combination of DSP settings which require more computational power than currently present will result in stuttering music.
If you plan to use DSP on Roon heavily, we suggest to install Roon as scenario 3, using the innuOS server as a Roon player only and using a powerful PC (Windows/Mac) as the Roon Core server.

Innuos is being 100% honest about it. Draw your own conclusions.
I do use my ZENith MK3 as a Roon Core, works perfect, but I only do simple DSP to PCM up to 192.
