WoutoudXduoo XA10 is a good sounding product with dual AKM chips and class A amplification. Soundnews has a review of this in youtube. Measurements are not everything. Many acclaimed dacs/amps were poorly rated according to the sinad measuremnts in ASR. Schiit bifrost 2, asgard3, modi multibit, fiio kj5 pro, ifi idsd blacklabel, earmen tr amp etc are few examples. There is also a good video on sinad by Andrew from 'The Headphone Show'
