NAD M66
The integrated DAC unit in the NAD M66 is based on ESS Technology's Sabre ES9038PRO chips. In addition, there is also an MM/MC phono corrector. But this is not the end of the list of distinctive features of the NAD M66. The new product implements Dirac Live Room Correction and Dirac Live Bass Control technologies, "which allows the NAD M66 to provide a more accurate indoor response than any dual-channel component ever offered."
