I’ve had a very good experience using Roon convolution with filters from homeaudiofidelity.com, sounding much better than MRC as implemented by my C61R. -Now enjoying the HAF benefit from a stereo smiley 5k setup as well.

Maybe MRC filters would work well in Roon for my environments, but I haven’t tried that.
