@Craig_Palmer , you now opened another rabbit hole for me
I will look at the NUC w/ Rock + Allo Digione option and do room correction with a mic and save the money for a better stereo amp. Now the debate on the Digione vs. Digione Signature with battery / LPS setup.
@philr, I could use multieq xt32, but generally leave the Marantz in Pure Direct Mode which turns off multieq xt32.
@R_Neal, This type of setup I also debated at length. My only pause was having a computer in the same closet as the Marantz, but maybe I am being paranoid. I was exploring the Topping DACs, but I would need to question if it would sound better than the DAC built inside the Marantz. I guess only one way to find out
