@mattsca I agree that doing the DSP BEFORE the DAC is ideal. The MEN unit likely allows your vinyl to also be used with DSP.
Since you are a ROON user you should talk to Mitch Barnett at
Digital Room Calibration Services, Convolver, Headphone Filtersets
He creates Convolution filters that run inside ROON. The filter is a customized DSP for your speakers | room | listening position.
I no longer use my filters since I have different speakers and different rooms.
