Chuck,
What modders can do is use high-end parts that are not cost effective for even fairly expensive production units, such as the SCD-1. But I'm pretty sure the engineers at Sony know a lot more about circuit design than whoever is modding your unit. Sony can afford to hire some smart folks. The use of balanced lines is common in commercial applications where long leads are needed. So I'd take the explanation provided by your modder as just more of the mysticism that previals in high-end audio.
