I did another test today. I carefully listened to the Mac/USB/SPL Director DAC combo for a while before changing to the Lumin. What I "think" I am hearing is more depth in the sound stage, more details on decay of symbols, more ambient feeling like hearing the room of the instruments echo a bit indicating they are not in a treated studio but a live club. I did confirm that the differences require close listening to be heard. This again today was not night and day differences, in fact the differences in my DAC's, amps, even speaker cables reveal more of a sonic difference than the streamer experiment which remains boggling. I have watched/read reviewers say they hear sonic traits/differences in streamers but I may need more training to hear significant differences. That said I am going to continue playing around and borrowing any streamer I can to continue this experiment. Welcome all thoughts and comments.
Thanks JH
