I have a Node 2i outputting via coax to Topping D70. I can hear subtle differences between the D70 and the onboard DAC-but they are subtle. Qobuz sound pristine and perfect to me on this set-up, as do my local files.
Pretty sure the engineers on this site would laugh at these comments if they weren't busy designing DACs. The filters have no effect on bass or midrange for certain and only marginally in audible higher frequencies.
