110 ohm Digital cable with 75 ohm input and output

My transport has a 75 ohm digital out (RCA only). My DAC has a 75 ohm digital in (RCA and BNC). Someone told me to try a cable that's a 110 ohm digital cable but is only wired with RCA's.

So it sounds ok- what are the pitfalls of running a cable with the incorrect characteristic impedance? Or is the cable truly a 110 ohm cable only when it's wired in a true balanced mode, which this is not?

I'm confused

Al- thanks for the considered response. Yeah, running a 110 ohm cable between two 75 ohm terminations sounds goofy to me too. But I'm listening to it now, and it sounds quite good.

I don't understand why anyone would purposely design a cable that uses three conductors, is intended for a balanced 110 ohm characteristic, and wire it unbalanced using RCAs.

I never said better SQ-

The other digital cables I have in house are Belden 1694A and Black Cat

The Belden and Black Cat do not sound identical. Black Cat is the smoothest, the Belden the most dynamic and this 110 ohm cable? Somewhere between the two
