@ivanj you haven’t understood what was written above. Try reading it again.
ALL cartridges are balanced. The cable type (RCA or XLR) doesn’t make a difference.
If you have RCA outputs from your tonearm cable but your phono preamp only accepts XLR, just get RCA to XLR adapters, being mindful to keep the ground wire of the tonearm cable connected to the phono preamp.
