R2R NOS PCM vrs analog playback

I have had several DACs in my setup.  The only DAC that has come close to the analog I remember is the Red Wine Isabellina.  The tone, texture and sound staging are quite remarkable when compared to other DACs I have used, some costing 2 to 3 times more then the Isabellina.  The essential element that I find missing is the ambient decay that resonates in a totally black background.  I would appreciate anyone's impressions of the newer NOS designs from Schitt or Metrum. Specifically, do they voice the intimate kind of bloom that surrounds instruments and vocals in a way that approaches analog.  As a point of reference, I am also familiar with designs by Berkeley and Lampizator. Any comparison to the three DACs would be appreciated.
