RE: Thank you Lew

Balanced cabling was developed to combat issues related to transmissions over very long runs of cable (hundreds of feet to hundreds of miles).

The short runs of cable in your system may not show any measurable noise reduction from using a balanced run of cable.

The effort to utilize balanced lines may require vastly more components than otherwise necessary (even transformers in some cases), it may cause other impedance issues, as well as inducing more self noise in the actual circuit itself.

For example, if you take the signal off your phono cartridge and send it into the grid of a half of a 12AX7 with a CCS loading the plate, you will get more gain and less tube noise than running a differential long tailed pair. In my experience, this additional noise is more audible than noise picked up by the 3 feet of cable coming from your tonearm (unless you run it right on top of a power transformer).

There's no free lunch in circuit design.
