If SE CKT, using RCA or XLR IC would make difference. But for balanced CKT, XLR will benefit from more gain, CMRR, .... CMRR is more the power supply related, a better power supply will help also. Lower RF noise will help both SE and BL, but not make SE the same as BL.
Running balanced. Difference between XLR vs. RCA.
Would like to know the difference, if any, in running an amplifier, or preamp, in a balanced mode with XLR connectors or running balanced with RCA connectors. Is there any benefitial difference between the two if the runs are kept at 1 meter. I have an amp and preamp that can run balanced with either.
