I went right to the source and asked w4s about the diffence in sonic quality with async USB. They acknowledge that the DAC-1 will not sound as good as the DAC-2 without the upgrading the CAPS ($50) and upgrading to async USB ($250). Since that is only $200 less than buying the DAC-2, not sure it is worth it. Guess they prefer to sell DAC-2.
I am back to thinking about the Ayre QB-9. For my uses, they did the right thing keeping the interfaces simple and putting the design into the quality.
