Aha I missed your previous commnet that the noise added is the dither shape . That's better ? So MQA adds a dither shape ? So the signal is properly resampled with dither to 16 bit in MQA . If you decode MQA data wold the dither shape curve continue >20 kHz . The studio in most cases did use some dither in the 24 bit realm to ? But that is probably not preserved in the MQA process . Meridian , do think that there is a "proper" dither shape some of thier older processors had several to choose from , but nowadays they use some unspecified shape as a part of thier secret sauce in thier audio gear . It's probably what I listen to everyday when using my digital volume control . -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
