Even if it is a "pseudo-balanced" setup, it very easily could sound better balanced. I really doubt that is has anything to do with the actual connector used. But if it also has RCA connectors in addition to the XLRs, I do not think it will help matters any to muck around with adaptors. Unless, as Albert said, you just happen to have a really good set of XLR cables sitting around, not being used.
