Let me through a big curve ball. I suggest that you try the MSB discrete with the renderer module. Add a gigafoilv4 with the ifi elite power supply. This should run about $15,000 usd. This would allow you to get rid of all the Innuos gear and run roon on a Mac mini or nuc with more processing power and better interface and library management too. The renderer is also a roon endpoint.
My friend and I compared both an MSB discrete and Reference with this setup vs the same dacs fed by the Innuos statement with Phoenix net. We both were shocked that the gigafoil setup sounded better and more real with less digital glare. This was on a system with Estelon X Diamonds, MSB s500 and a stromtank. I found the same results at home with my system with Rockport Atria II and Dan D’Agostino momentum M400s and Momentum HD pre.
I am not sure if this is in you budget but if you are looking at esoteric it may be.
