I Don't know JAC about DAC.... help please

I would like to get my first DAC but have lots of questions. Is it only for CD, SACD etc or does it also work with DVD's? What is the difference between a CD Player and CD transport? Where is the price point of diminishing returns, meaning I don't need a $10,000 DAC for my $800 CD player. Any recommendatiosn to get into a DAC sub $1000.....

Try an Ack-Dac or Scott Nixon tube dac at your price range. Both have many great reviews.

Here is a useful and recent thread:

DAC's are for CD's only. You might consider getting one that you can add a USB interface to later when you move your music to your laptop or PC. And dont be reluctanct to buy a used one. They dont wear out.
