I did some testing for 3 players, Ibasso's DX50/90 and the Ipod 4g and they show different problems, some of them has marginal jitter performance(low frequency jitter) and the DX50 has marginal IMD performance. Choice of DACs like the 9018 can determine the signature of the DAP, even if the distortion discreetly measure below the threshold of audibility, I do believe the sum of distortion is audible to users.
