At least try the SPDIF Coax connection before moving on to outboard DACs, which are a bottomless pit of options.
D/A converter built into amp.
One simple [well maybe not] question. I am streaming Qobuz into the DAC inside my Hegel H360 amp and it does not seem to have the performance of my Hegel Mohican CD player as far as depth and resolution. Would a stand alone DAC fix this? FYI I am using and Audioquest toslink cable.
