Herman....that is incorrect. There are DACs that support ASIO - but they must have USB input. It gets the signal via USB from the player (which as you state, must support ASIO output) and it must be able to utilize that data before sending it to the D/A process.
Many USB interfaces are like this: they have USB input and a built-in DAC, although many people simply use those to get USB out using ASIO, have a digital signal generated, and have that digital signal sent to an external DAC (such as one which does not have USB input). A good example of this is the EMU 0404 USB or Edirol UA-1EX. I used the latter prior to getting the external DAC - fed it USB, it supports ASIO, and I used its DAC capabilities too thus outputing an analog signal to my amp.
