Wondering if I can get a little smoother of a sound without sacrificing detail and separation.
Of course you can, and I don’t think going to a pro DAC is necessarily a good idea given what you’re looking for. . You went from a very neutral DS DAC to a tubed R2R, which is like going from one extreme to the other. I’d suggest a SS R2R DAC that’d more split the difference and give you slightly smoother yet still very detailed and transparent sound. I think the Musician Pegasus or Soekris 2541 would be excellent options to try if you can, just to name a couple. Hope this helps, and best of luck in your search.
