Really you answered your own question already "2 TB’s is plenty". I will make it easy and say that GET the N100H its 2 TB internal storage and has no DAC so you just run a USB audio cable to your MAC, and control the thing with the AWESOME Conductor app for tablets. As far as sound goes ALL the Aurenders sound completely gorgeous! You will be happy :-) But you have to plug the Aurender in using the Ethernet cable to router if you want to stream effectively and use NAS or a PC for extra storage. For $2700 nothing can touch it when you factor in the Conductor app its a #1 pick!
