I would certainly benefit from a case, or even a dedicated bag like that. I am a student that moves every 6 months. It is kinda hard to carry my K701, K242 and Schiit Amp/Dac soon to be :P. Not to mention the cables im also going to buy.
One of the few things delaying my planned purchase (Schiit Valhalla, Bifrost, Cardas MicroTwin, Cardas USB) is (not portability) transportability. Should take as much space as a large suitcase, and weigh a LOT! Sometimes this hobby gets on my nerves.
