jedinerdInteresting question. MD is not, technically speaking, a reseller but a group buy organization so from warranty point of view, MD is the first owner. I'm guessing it's a question of transferring warranty to the second owner.
AnzialAs far as I understand, MD isn't an owner, just a middle man. You're technically buying the speakers from Audioengine through Massdrop. MD customer service seems tight, but I bet a warranty would fall to the manufacturer. I'll let someone more official chime in.
