Aurender A10 Has a built in DAC. So i hook a Yaggdrasel DAC Up to A/B it. i could hear no difference at all.
Odd you should have heard some differences as the A10 is Delta Sigma conversion and the Yaggy is R2R Ladder Multibit, which I’ve always preferred to listen too when it comes to 16 or 24 bit PCM (Redbook) source material.
