Received mine yesterday from my APO forwarding service. Very cool looking loaded up some Flac albums and listened with the Massdrop AKG K7XX, mellow sounds able to drive the AKG's to some decent levels. Simple controls, great if you just start and listen to a whole album at a time. Great midrange for the vocals and on the treble it's not so bright but I can hear the guitars being strummed. I got the silver one and I like it. Will try it hooked to the Fostex HPV1 tube amp, but right now by itself it's sounds really good. Happy with this drop.
