Great post Audioengr. I would also add that "smoothness" in many DAC's is achieved at the expense of high frequency articulation i.e. controlled roll-off in the treble region. Not only is tonal balance part of what equates to "smoothness", so does transient response. I think that this is what Audioengr was getting at in terms of "dynamics". A component that lacks transient response will demonstrate a "softer" presentation. While the combination of soft treble response and reduced amplitude of peaks may present a "smoother" presentation, it isn't very accurate or nearly as good sounding as what a well designed digital system is capable of.
