So im going to order my dodd buffer this week and since its going to replace my receiver im going to loose a way to listen to my cans at night. Since the buffer and my dac are off the grid id like to keep my amps off too but im having a hard time finding something that runs on 12v. DIY is ok. I have a pair of HD555's and a pair of brainwaves M3 iems and ill be geting a pair of high end high ohm cans in the spring.
