*Bsic balanced is slightly more expensive for obvious reasons (complementary circuits)
*Balanced is useful because you just have to match circuits -- not components (so easier to implement linearity) + you get common mode rejection.
*Of course, in balanced you get twice the circuit noise
*Single-ended, in "ultimate" implementation, would be extremely expensive -- it would require component matching for each channel and extremely careful ground to ahcieve ultimate linearity. Forget it -- but that would be the best.
Finally, the rca connections are horrible; the xlrs are much better & reliable. No wonder pros use balanced as standard.
