Love Massdrop. Since you asked, I can think of one. Centrance M8. Probably sets the bar currently in portable DAC/AMP and incredible flexibility. I know that the Centrance Dacport LX drop did not go well but I am confident if you did the M8 drop, you will meet your quota. That said, this does sound like a fine unit too.
