thats nice and rare. Some modern dac have also this feature to please audiophiles. It seems to be an dualopamp. look up your opamp and if you are not happy with it you could replace it with a burr brown opa from texas instruments. I dont have your specific opamp so I cant give a specific recommendation but those audio opamps from burrbrown are fine.
