    I currently own a denon AVC-A1SR amp. I am thinking of buying the denon A11 dvd player.
    Which of these two machines has the best DAC in regards of "ordinary" cd playback?

    DSD 1790 (DVD-A11) - No information, however what I can gather, it is suitable for SACD (DSD) conversion. As to which is better, I would decode stereo in the A11 and use a bypass to the amplification stage of the 1SR.

    Hope that helps!
