@rushfan71 , this is why it is so important to hear stuff for yourself. Although you and a couple of reviewers indicate the Morpheus may have a touch more meat on the bones than the Adagio or Pavane, I have spoken with several others who have indicated they hear very little if any difference between the Morpheus and the Adagio. I have heard from a couple of people, and from Granny's post below, that the Morpheus is thin sounding, and from one industry insider who recommends using a preamp or buffer with either the Morpheus or the two top Metrum DACs.
My personal finding with both the Pavane and Adagio
(both of which I have owned) is that they have good tone and detail but need a preamp or buffer to achieve the level of body I enjoy. I am hoping to find something with a similar level of tone, detail, and naturalness, but with a bit more body and weight. It seems the Bricasti M3, Holo May KTE, and Mojo Mystique may provide this and also possibly the Rockna Wavelight and Terminator.
