I too use the Bricasti M5 with Roon and am very happy with the sound of my digital side.
I have the Roon Nuclues One > Bricasti M5 > SPL Diamond DAC > ModWright Analog Bridge > Rega Aethos > Triangle Magellan 40th Anniversary Duetto's. I love the sound but am always trweaking with rolling the tubes in the ModWright.
I think the Bricasti M5 is very well made and the sound is amazing.
