Denafrips Ares 2 for AVR center channel application ??

Im not interested in 2 channel audio Just yet , im interested in adding a dac just to play music over center channel music mode , I just dont know what the receiver does with this analog finished signal once it processes it , would it be better in any way or is a Dac like the Denafrips ares2 reserved just for 2 channel. I called crutchfeild they said yes it would help but he didn't sound to sure of himself . Im asking this because in the Ares the ladder dac has a ladder for each channel so the left and right RCA gets amplified as is , but if Im asking an AVR to process this signal thru 1 channel in music mode , Im looking for an improvement or is it a total waste of time? 

No , its is not for netflix this is for music only , I have a Node 2I as a streamer and want to use an external dac going into my AVR on an Input (cd) Via left and right RCA , What Im asking is if I want to take my digital stream from my Node and plug it into an external DAC I have a left and a right RCA , will playing music from the dac give me better center channel audio or is this only for 2 channel music ?    I like music mode where the music plays from the center and the subs .  Will playing Tidal HIFI over a Node2I streamer feeding a high end dac feeding a AVR on anyone its RCA inputs sound any better. I cant get a straight answer on this .

Denafrip DAC has problem with netflix and other streamer. The sound is lagging scene. You better just use a 5.1 7.1 AV receiver for video.
