Help w/Stageline to Nac282 lower auxilliary

I want to use my two hi-caps to power my nac282 and have my stageline connect to the 282 through the lower auxiliary 2 socket. It doesn't work for me. I can do this with a friends nac252/supercap; no problem but I have only been able to run my stageline if I dedicate a hi-cap to it robbing the 282 of one. If there is someone who could advise me, I'd much appreciate it.
