Balanced 4.4mm to single 6.35mm adapter/converter?

[L. Kenter]

Hi all, 

 

I just got a balanced cable for my iBasso SR2's only to realize after receiving my order, that this cable has a 4.4mm plug. 

I'm using an EVGA Nu Audio (non pro) which has Line Out over RCA and a single 6.35mm Headphone jack.

As far as I could find the EVGA Nu Audio should have a balanced output but after learning some more about balanced sound I'm starting to doubt it.

 

So my questions are; does my sound card actually have balanced output or not?

And if it does, what would be the best way to hook up a 4.4mm cable to this card? Would something like this DD HiFi DJ65B work, would the output still be balanced?

And if it doesn't, is it worth to get an external DAC with a balanced output and hook it up to the sound card?
