Yes, as mentioned, I was using the Mac Air with external DAC but wonder if the circuitry inside the Mac / laptop is "dirty" as claimed and switching to cleaner streamer/player will render better SQ. So, are you saying that switching to streamer as the player won’t render better SQ based on your experience? Please confirm.
I was using the old (2013) Mac Air that has the option for higher sampling rates but you need to change it every time. Also you need to switch it to highest rate in order to accommodate all the high-res. PCM files I had. So it means some of the lower sampling-rate audio music will be over-sampled. I heard the Asio plug-in in foobar 2000 could get around the issue but I do not have luck to get it working yet.
While I was done with replying your first msg, your 2nd msg pops up. I will try that. Sound exciting although I am not tech savy.
