Guys if you haven't read the two reviews of the DAC-10 and most if not all of your questions will be answered. The TAS review deals more with the sound of the unit, but the other review delves more into the technical issues. Plus remember this is a $1500 DAC/Preamp and not a $15,000 to $30,000 Lampi GG or Berkley Reference DAC. It is not the be all end all, but it is a great unit for the price and much higher.
