Regulator proximity to opamp

Hi I need to create a +-15V regulator for an opamp.
But I don't know what is the best for low noise, to have the regulator close to the opamp (lower impedance) or far away from the opamp to reduce noise ?
What is "industry standard".

What is the best :
BRIDGE > CRC > REGULATOR >>>>>>>>>>>>>>>>>>>>>>>>OPAMP
BRIDGE > CRC >>>>>>>>>>>>>>>>>>>>>>>> REGULATOR >OPAMP

Thank you.
