I listen to SACD with my Oppo 105 outputting the DSD layer over HDMI into the HDMI input of my Bryston DAC. The Oppo program menu makes you decide which layer of the disc that you wish to output.
Magnets Universal Players are made by the same engineers that created the Oppos and the menus are identical to the Oppos.
Given what the OP has said about his budget-it seems to be in the 5-7 K range if I understand correctly- he should be able to afford a Magnetar and a good DAC with HDMI input. He could just try the Magnetar first with the internal DAC and if he’s happy stop there
