samschua@yahoo.com.sg,
Thats a step in the wrong direction in my opinion...The Wadia 6 DAC section is quite a bit better than the brick-wall filtered W-12 DAC (which is nice, don't get me wrong).
Still, the W-12 will at best sound different than that 6's internal Dac section...If you are looking for an improvement...better to look at a newer player in my opinion.
