If equipment supports the AES47 standard, the the cable will make less difference-compared to RCA.
I suggest you PM Ralph Karsten (Atmasphere) for a complete reasoning- though I think it is on his website.
As far as personal experience goes, I bought some cables from Ralph when I bought his amps and preamp. I think it is Mogami.
I though I was done with it, but I tried some AQ cables (Mackensie?).
To be honest, I couldn't hear a significant difference between the two.
