For a sweeter midrange your should look at the Playback Designs MPD-8, Aries Cerat Kassandra, EMM Labs DA2 V2 or soon to be released V3. I would also think MSB Premier or Reference. All of these are going to be sweeter sounding than the dCS.
I have explicitly had people move from dCS DACs to move to PBD for this very reason and can say confidently that Aries Cerat and EMM are sweeter sounding than dCS as well. MSB I have not had in on trade and have not had in my system so I suggest that based on reputation.
I would hope it is obvious that I am a PBD, AC and EMM dealer and have no affiliation with MSB.
