I have a teac in my bedroom system, and I'm interested in mods. Two options, one, get whatever mods possible with out going battery, and leaving the amp close to the speakers. Two, getting the battery mod and moving the system by the bed, ie 15 foot speaker runs. I know it's lame, but I know I won't get out of bed to shut things off. Now I leave the teac on 24/7, pre and DAC don't need to be powered down, and the source has auto shutoff .
