Modi2u sounded too bright to my ears, in combination with Magni2U often annoyingly sibilant. There was a brilliance and plenty of details, but I couldn't listen for long without fatiguing my ears. Also the soundstage was congested, and sometimes the high strings in orchestral music sounded a little bit too shiny.
Sanskrit6 is more spacious, more relaxed, more laid back, smooth, and has probably the deepest bass you can get in this price range, courtesy of WM8740. It is a little bit veiled in the treble, especially if you compare it with Modi2U, but overall it is much more pleasure to listen to. I can put my headphones and listen for hours, forgetting about the time.
