I am also interested in reading a more detailed review of what you are hearing from the Morpheus after you have burned it in. I am particularly interested in any comparisons you can make to the Metrum Pavane you previously owned. Having owned the Pavane, Pavane L3, and Adagio, I am very interested in a DAC that delivers the resolution, natural tone, and dynamics of those upper level Metrum DACs while bringing just a touch more 'weight, body, tonal richness, and a more natural sense of the space of the recording" as stated on the Sonnet website and seconded by Srajan in his 6moons review of the Morpheus.
While I have had no soundstage issues whatsoever with those upper level Metrum DACs listed above, I also own the Jade (Onyx with volume control) and I can understand how @donquichotte might be used to a "bigger" sound. The Jade is a good-sounding DAC for the price but the additional DAC modules and larger power supply in the upper-level Metrum DACs do seem to provide more of everything.
