@dc655321 @andreasmaaan the reason I suggested ASR run an iPhone/Lightning adapter test is because it could then appear in other ASR reviews as a perspective/comparison point. That little Lightning-to-Analog adapter might be the 'best selling' and 'most owned worldwide' DAC* right now (notice my quotes). I don't doubt the measurements made by Ken Rockwell or Archimago, but those measurements won't appear in Amir's awesome ASR review charts as comparison data if ASR doesn't have that data in-house with consistent measurement gear and technique etc.
