Fyi, Audient noticed this and continues working with issue. New fix coming, currently in test and validation phase. I hope that you gurus remeasure this again after next firmware released.
Could you @JohnYang1997 measure this device again? Just got information from Audient that phase issue is fixed on latest firmware. Would be great to see is it true by measuring this again..
(I also informed l7audiolab.com and asked if they can retest..)
