Glacier: less powerful, sparkle treble, lush and musical mid, lack of sub bass. The DAC section can be used with PC and certain Android phones.
I, personally, prefer the Glacier as it much more musical compare to the MK3. Yes, the MK3 can drive many hard-to-drive fullsize cans with authority but the sound sign is just not for me.
