Wyred 4 Sound Dac 2 OR Wadia 121?

For several reasons, the Wyred 4 Sound Dac 2 and Wadia 121 have feature sets that are important to me.  So I am wondering if anyone has done a side-by-side comparison on their sonic features?  Which sounded best in your setup and why?

FWIW, listen mostly to big band, classic rock, and female vocals.

Thanks for the input,
Chip
