This listing is for the silver Mhdt dac only with upgraded tube. Beautiful midrange on this one. If you have any issues with digital harshness, sibilance, excessive brightness this dac will solve it. Very fluid and “analog” sounding. Not as sharp as most current dacs. Didn’t quite work for me but I could see it being perfect for some people/ systems.
