Since you like vocal, you may not go wrong with audiolab Dac. Audiolab DAc is audiophile grade DAC, their internal Parts & design is far better than cheap dac. Unless you care more  about hifi effect like Drum Hitting, Pure instrument music, then you better get multi bit dac. I got my friend sell his multi bit MSB’s 24/96 Link DAC  & get meridian  bitstream  203 dac, Because he feel it more musical & vocal is better.  So most important, you better plug the audiolab dac in your system & let yourself to decide this new combination is suit your taste or not? But please use good digital cable for testing.
