I know that the newer "slim line" DV-440 is rated for 24 / 192 output use with the internal DAC's and is selectable for use with 48 KHz or 96 KHz as a transport through the digital out's. Other than that, i can't remember any specific model numbers or specs. Sugarbrie may know more about these as i know that Stan Warren likes / uses Pioneer DVD's quite a bit. Sean
