most computer battery backups apparently sound atrocious...putting lots of noise out.
I've used the Red Wine Audio battery supplies (they are not for back up, they replace the AC). My Nagra PLL and VPS (pre and phono) have off board AC supplies and the main units take 12volt dc in..so the Red Wine Black Lightning was fantastic improvement. You have to spend a lot in AC conditioning to maybe equal the red wine battery's...
Does your DAC have a DC input? If so, I bet this route makes it sound better...
