Thus, I sensed an imbalance of 0.2db lower output on the right. As a result, I thought E30 highs are better with a particular song with lots of echo trial on the right. Then over the weeks, I adjusted my sitting position more to the right to get more balanced sound, and thus I got the impression that x16 highs improved over time.
It is highly unlikely 0,2dB overall channel imbalance will be audible, let alone change echo trails or treble quality perception.
I mean, just listen to the DAC using music and then process the same recording where you change the amplitude 0.2dB of one channel and listen again. Use the L30.
Then if you experience the same sensation and in an ABX test you can reliably detect differences and have posted a link to the used recordings (or mail them to individuals willing to analyze/listen) then the above becomes plausible.
