I bought the iFi xDSD to go with my iPhone 11 Pro and Shure SE846 earphones to stream hi-res on Qobuz and I’m struggling to tell the difference between the xDSD DAC and the RMCE-LTG lightning cable. My guess is the DAC in the lightning cable is as great to my ear (even though now discontinued) but that is confusing because of obvious reasons that comes with the xDSD e.g., size, cost, features, specs, etc. Anyway, anyone have recommendations on what to hear out for to find noticeable differences in a DAC?
