Rega p6 RB330 how to get XLR output

Not sure you should rewire the captive arm cable as it will affect resale value. Why not use a 3 Pin Male XLR To 2 RCA Female Y Cable?

Using RCA to XLR does not help?. Does it ?.

You cannot simply go balanced from the stock Rega arm (unlike almost every other arm out there) to your phono stage because Rega combines the ground with the left channel internally.

Separating the ground from the left channel, or a total arm rewire utilizing a more conventional grounding scheme found in most other tonearms, will be required.

If you modify the existing wiring, you would then need to remove the RCA’s and properly terminate with XLR’s.

Link below is to the necessary modification to disconnect the ground from the left channel.
