Not sure if you are aware of this but if you're Rega 700 has the stock wiring in it, you will need to do some minor surgery (or have it rewired) to configure it for balanced.
Rega is one of the very few arm manufacturers whose arms are not very simply converted to balanced signal transfer with the addition of a balanced tonearm lead.
